Types of mountain bikes: all the different mountain bike categories YjE2MmM1MDI1YTY4YThiODM4NGMyYzEyYWE5NmNiYmVjZWY0NzkwYjc4YTMx Outdoor equity, climate action, places we love. Designers can manipulate the path of the instant center to get their desired effects on performance at specific points in the travel. Shock: Rear suspension unit. 5. A bike with just front suspension (a suspension fork) is referred to as a hardtail, a bike with both front and rear suspension is referred to as a dual-suspension, or full-suspension bike and a bike without any suspension at all is known as a rigid mountain bike. MTB Podcast | Sit onto the saddle slowly, and allow your weight to press down with your feet off the ground. You'll find out about the varied MTB styles and disciplines. The front suspension, or fork, takes a large majority of the riders weight, as mountain biking sees the rider often riding with more weight over the front of the bike. Different riding disciplines place different demands on the bike and the rider, so the suspension will vary accordingly, with the amount of travel - which is the amount the suspension is able to compress (more travel = more give = more impact absorption). Mountain bike rear shocks consist of two telescopic tubes that slide into each other. Overall, suspension design balances the absorption of impacts, the effect of braking forces, and pedaling efficiency to create a system that best serves a bikes intended use. Without the damper, the fork would compress and then uncontrollably return. Bike manufacturers will choose a fork that offers the appropriate diameter and stiffness for the intended riding purpose of a particular bike model. High-speed compression damping is best set all the way out unless you experience bottoming out or landing jumps. Trail riding and the corresponding trail bikes refer to what can be thought of as everyday mountain bike riding. When you purchase through links on our site, we may earn an affiliate commission. The o-ring lets you fine-tune the sag setting by allowing you to measure the travel. Our goal is to provide easy to follow, step-by-step cycling related guides, and reviews for bikes & gear. Ryan eventually gravitated toward enduro and downhill racing but has also been found in the occasional road and cyclo-cross events. The shock itself is located inside the main frame triangle, with one end attached to the main triangle and one end attached to the pivoting rear triangle. Rebound Damping: Controls how quickly the suspension returns from being compressed. Another critical measurement in bike suspension fork design is stanchion diameter. This system also uses a solid swingarm connecting the main triangle to the rear axle and pivoting around a single point. However, most shocks and forks offer extra adjustments that can fine-tune your suspension even more. Sag: The correct air pressure or coil spring choice is determined by measuring sag, which is how much the suspension compresses simply under the rider's weight when sat on the bike, this is with no further input from the rider or the trail. Repeat this single explosive bounce, but focus on the rear shock this time. Coil sprung shocks are still very commonly used on heavy duty downhill and enduro mountain bikes, as they tend to handle heat better, but come at the cost of less fine-tuning adjustment options and added weight. They are completely optimized for the most challenging downhill trails, and if you try going uphill on one, youll probably be better off walking. Visit our corporate site. The best way to figure this out for yourself is to get to riding and follow the fun. Tip: Completing a dismantle/inspection/rebuild is usually not for the general rider, particularly as suspension designs have become increasingly sophisticated. REFRESHER COURSE: SUSPENSION TUNING FOR DUMMIES - Mountain Bike Action We check over 250 million products every day for the best prices, Whereas full-suspensions have a rear shock, Cross-country bikes are designed for speed and efficiency, Trail bikes feature 130-150mm of suspension travel, Enduro bikes are biased toward descending but can still climb well enough, Downhill bikes are meant for one thing: going downhill fast. England and Wales company registration number 2008885. If such markings are not available, the use of an o-ring (if fitted) or tied rubber band will allow you to measure the sag with a ruler. My understanding is its basically a dw-link, but one of the pivots is cleverly placed at the rear dropout, which is split. The average recreational mountain biker wont notice much difference between rear mountain bike suspension types. Be aware if you are wanting to change or upgrade your shock that it will fit your frame and you have the right mounting hardware. Rear suspension is only found on full-suspension mountain bikes, and is commonly referred to as the rear shock, or shock for short. Carbon will be the lightest and steel will be the heaviest. Suspension travel describes the amount of movement a suspension fork or rear shock has. Fox recommends the following: The o-ring lets you fine-tune the sag setting by allowing you to measure the travel. Interestingly, the first rear suspension MTBs actually used forks in the rear dropout, but this was an ineffective design and was quickly discontinued. Pedaling efficiency refers to the percentage of energy that reaches the rear wheel from each pedal stroke. Before beginning, ensure that the lockout setting is off and that your compression adjustments are in the most open position. As a result, they can make suspension softer at the beginning of the stroke for small bump sensitivity and then firmer toward the end of its travel. You should use between 80 and 90% of your fork travel and roughly 90% of the shock travel during this test, indicated by the rings. | Image source: liv-cycling.com. Progression is set based on the force it takes to bottom out the suspension. As a result, they can reach an entry-level price point that would be out of reach with some of the suspension platforms below. Required fields are marked *. Alternatively, you can design Horst-link suspension to have high anti-squat at the beginning of the stroke and less at the end. In addition, there is no patent on the design, so that any manufacturer can use it. Low-speed compression: Controls fork performance during rider weight shifts, G-outs, and other slow inputs, by holding the suspension higher up in its stroke range. Everything You Need To Know About Rear Shocks - Cane Creek This results in oil degradation, leading to loss of performance and function. Nobody would argue that suspensions most important function is absorbing impacts. Mountain Bike Suspension Basics | REI Co-op In addition to the four configurations described above, popular brands have their own proprietary iterations that attempt to improve performance. This movement absorbs bumps to help keep the tires in contact with the ground for better traction and control and reduces the impact on the rider, increasing comfort. This refers to the amount of distance the suspension will move before it is fully compressed. Alternatively, follow these steps. A beginner's guide to mountain bike suspension design - BikeRoar When it comes to mountain bike geekery, perhaps no other area of the bike contains such a deep and mystifying vocabulary as the suspension. Manufacturers represent anti-squat in percentages. Measure the sag again by repeating step one and keep repeating the process until you hit your desired sag. Earn a $100 REI gift card after your first purchase outside of REI within 60 days from account opening. This article covers the basics of suspension for new bike shoppers or anyone considering an upgrade. The trade-off of higher efficiency is a less plush ride. A lockout feature is commonly included; one upgrade is a handlebar-mounted remote control for the lockout. The ultimate guide to mountain bike rear suspension systems Famed suspension designer Dave Weagles dw-link was a precursor to Maestro, and Weagle was locked in a legal battle with Giant for about a year before eventually dropping the lawsuit. Hardtails do not have a rear shock and have either a suspension fork or a rigid fork. Pinkbike Poll: What's Your Favorite MTB Suspension Design? NDNjZDAwZDM5ZjE1YTY4ZGFlNWFmMjFlNTE4MzM4Yjg3M2I2ZjMyNGJhMjRk A fork designed to handle harder and faster hits needs wider, stiffer stanchions to ensure they dont flex too much and cause damage. Trunnion mounts have started to become more popular within the last few years with frame manufacturers. We will cover setting up sag properly in a later article, in the meantime, your suspension will have a set-up manual available online that can help. Because they have fewer components, hardtails are cheaper than full-suspension bikes, but there are top-of-the-line hardtails too. This is sometimes known as a faux bar design because while it utilizes a system of linkages like a traditional four-bar design, there is still just a single pivot point. It is comparatively short: 1.5 to 3. Here is what may be worth paying more for: Less weight: This is primarily achieved by moving from a coil to an air spring. Excessive oil leak onto the stanchions around the top of the sliders. The best way to know what dial to turn or button to push is by looking up your shock on the brand website and reading its instructions manuals, trust us, they are very user-friendly and well laid out with easy to read graphics and instructions. With a host of terms like four bar, faux bar, virtual pivot, multi . Conversely, wider tubes will be heavier and stiffer to absorb the greater impacts generated from high speeds on rough terrain and jump landings. Many bikes today have both front and rear suspension systems. Although most suspension brands offer a similar range of adjustments options, the mechanism to do so will vary. This swingarm rotates around this pivot with a fixed instant center throughout the travel. Anti-rise is the effect of braking forces on the suspension or how much the suspension compresses or extends from braking. Play or knocking between the stanchions and the lower sliders. Find a sidewalk nearby and ride off at around walking pace while sitting on the saddle, noting how the suspension feels when you drop off. ZDBjNGRmOGRkZWJkOTBiMDVlZWZmNzc2MjU0OGQ1OGI4MTAwNTY3Mzk4YzRi Sag refers to how much the suspension compresses with just the riders weight on the bike. Today, he regularly rides the trails of Durango, Colorado, and is aiming to make a career out of chronicling the sport of cycling. Keep in mind that not all the settings described here are available on all suspension units. MWU3MjgzNWMyY2E5OTg2OGFjZGJjYTQ2NGZjMThmZTI1ZmMxNzBjNDY1NWE3 General guidelines: Sag enables the wheel to follow undulations in the ground more effectively, allowing the suspension to extend so that the wheel can drop into depressions in the trail. For full-suspension bikes, you want to ensure both the fork and the shock return at the same speed. This essentially gives the option to turn the suspension on and off, or provide some level between. What is suspension travel? Thats one reason why you should always test ride a bike before buying to observe its individual characteristics. Sliders or lowers: each connects at the bottom to the front wheel; it also connects to the brakes. This design allows engineers to manipulate anti-squat and anti-rise characteristics at different stages of the travel. Rebound damping is the most important damping setting. NSR250 Forums - View topic - SE/SP Rear shock rebuild Modern mountain bikes are nearly all equipped with suspension. Anti-squat refers to how much the system resists the compression that occurs during pedal bob, creating a more efficient pedaling platform. In other words, the riding you do, where you ride, how you ride and how you want your bike to feel all influence how you set up the rear suspension on your mountain bike and, therefore, which rear shock to choose. YWQxOGMzZTU4MzkxYWU1NTZmZDIyMzk1N2JhNGExNDE3NmIzZTAwZDVhYzk2 Its the low-speed compression thats typically adjusted when using a lockout control. NzU0ZDc0YjYwNDYzNTJjNTRmNDQ2ZmQyYTA4OTBkMjVmMDY0OWI2NjVkNTAx Coil spring suspension is the older of the two designs. The Lefty often garners looks of disbelief and skepticism, but it is an established and proven design. An air spring is a pressurized air chamber. A basic primer on mountain bike suspension designs. Mountain bike axle standards: the complete guide - BikeRadar Then, slowly stand up and assume an attack position without bouncing the fork. 100% would theoretically mean there is no pedal bob, as the squat and anti-squat forces cancel each other out. Spring Preload: Where air pressure is used to adjust an air spring, preload is the equivalent function for a coil suspension. There are so many different types of suspension setups for full-suspension mountain bikes, it's easy to be overwhelmed by all the various technologies, terms and choices. Coil shocks offer a more linear progression and finer tuning, but come at a small weight penalty. Each has its pros and cons on how it affects a bikes ride quality. Our guide below explains the common types of mountain bike thru-axles, as well. Each manufacturer accomplishes this in different ways, but one unique example is Specializeds Brain system. When measuring sag, its important to do so with your riding gear, so if you typically wear a hydration pack, be sure to wear it here. Simply put, its how the suspension reacts when you accelerate. What is the Best MTB Suspension Design? | Shop Talk - YouTube MTB styles and disciplines: Guide to 16 different types of - AWE365 Using the linkages, engineers can control the leverage ratio curve, so you can have a progressive curve instead of being stuck with a linear one. "We've been big fans of the K-series BMW since they were released in the 80's", Gustavo says, "and we've already built many K-series customs". More rebound damping produces a slower returning fork, less rebound dampening produces suspension that returns faster. Push down on the saddle to pump the suspension a few times to balance the air pressure inside. Anyone can join and everyone belongs. The suspension on a cross-country bike should not engage or bob when the rider pedals. Begin by getting dressed in your typical riding gear and carry your backpack or hydration pack if you usually ride with one. This helps counteract pedal bob when climbing. Full-suspension bikes are grouped into categories like cross-country, trail riding, enduro, and downhill, which we have listed here. There arent necessarily freeride-specific bikes, with riders choosing the bike that best fits their needs. Your access to this site was blocked by Wordfence, a security provider, who protects sites from malicious activity. Is it a linkage-driven single pivot? Head-tube angle is the angle that the head tube forms with the ground. The most simple suspension design is the Single-pivot, using a solid swingarm to connect the rear axle, main pivot and shock damper. From hardtails to full-suspension bikes, this is our guide to the different types of mountain bikes and what they're intended to do. Gravity-focused MTB disciplines favor progressive wheel rates to prevent harsh bottom-outs and increase small bump sensitivity. YTliNmFmOTE2ZTUzMmY3YWUyZTZhNzg0YzIxMGVmOWEzZjg1ZjdiODhlMTA3 The front wheel is attached to the fork lowers, while the stanchions are attached to the headtube of a bike frame, via the fork steerer. A trail bike will certainly have a dropper post, and it will have more powerful brakes than a cross-country bike. As one of the simpler and therefore cheaper options for independent suspension, the MacPherson strut has seen widespread use since its invention back in the 1940s. It is one of many factors that contribute to your riding enjoyment. Compared to the torsion bar system, the MacPherson strut is both large and expensive. 0% anti-rise means the suspension stays active and plush. ZTY1OTg5YzAyMWNiOTE5ZDkyMGFmZjJlNTNjNTMwYTE4MjVhYjRmOTY1YmY0 A continuous swingarm links the rear axle, the main triangle (on the top tube or downtube), and the shock. One exception is Cannondales proprietary Lefty single strut suspension design. last updated 23 September 2022 Choosing between a hardtail and full-suspension mountain bike depends on terrain and riding style Cannondale FSI hardtail and Scalpel full suspension mountain bikes (Image credit: DNA/Cannondale) With many price points and build options, a hardtail and a full-suspension mountain bike might cost the same. Your Honda NSR resource on the web! ZGVhOTgxZjllM2U1M2UxN2I3ZGM1YTg3Y2U3NmFjNzFkNDk1MDA2ZjhiYjM5 Bespoken Word the price of everything BikePerfect is part of Future plc, an international media group and leading digital publisher. Ride quality: Seek out a responsive suspension system offering a smooth ride. A bar is one element of a rear suspension system. Compression damping is often split into two types: Low-speed and High-speed. How to adjust mountain bike suspension - Bike Perfect A pricier fork is going to offer a superior experience compared to an inexpensive one. There are several possible adjustments you can make to suspension. Dirt jump bikes predominantly hardtails, although there are short travel full-suspension options available, and are meant for jumping or skatepark riding. Choosing the best mountain bike for your type of riding can be tricky, the good thing is that there are some general rules that define what category bikes are placed in to make things easier. As the terrain becomes more challenging, a rear shock will absorb the bigger impacts and keep your wheel tracking on the trail, allowing more control and confidence for the rider. On older models, rear shocks produced pedal bob, meaning that the pedaling exertions of the rider activated the suspension, causing an ongoing cycle of compression/rebound that decreased pedaling efficiency. Twin-link suspension is highly tunable, like four-bar suspension, but the curves arent as predictable. Firefighters may also use fire motorcycles to offer medical first . Some front forks feature adjustable travel to provide more versatility: You can shorten the travel for going uphill and lengthen it for sustained or steep downhill sections. The amount of travel required is specific to the trails ridden and the riding style; more isnt always better. To set the rear sag, move the thin rubber ring on the shock (O-ring) to the end of the shaft flush with the shock body (if your suspension doesnt have an O-ring, use a rubber band or a zip tie). REI and the REI Co-op logo are trademarks of Recreational Equipment, Inc. Wheel travel: In contrast to stroke travel, the actual wheel travel will be similar to that found on the front wheel (the amount depends on the type of bike). Raise your voice in the movement to protect and share life outdoors. Follow BikeExchange: Email | Facebook | Twitter | Instagram | YouTube | STRAVA. YzA4NTRmMjBhOWFjYTUxMWJkOWIzZWQ1NWYwZmQ0Nzg5YzlmYzhmMWJhN2Rj Basic Mountain Bike Suspension Designs, Explained MDI1OWFiOTU3MTQwNzFiZmE2ZjBmNjk3ZGFhYmU5OWJmMTE1MWRmZTQyMmMz The sag percentage is based on the total travel available, something that is often reflected in the total visible fork stanchion or shock shaft length. Start with the rear shock by turning the red rebound adjustment clockwise until its fully open. This section will cover the most important fork-specific terminology and the individual components that make up the fork. The seat stays and chain stays in a full suspension bike are part of the rear suspension linkages. Fox Float X Factory air shock (left) and Fox DHX2 Trunnion coil rear shock (right). However, there are notable variances between suspension systems. This section will mention several important suspension kinematics concepts, which we will explain in more detail in the following section. It is usually a measurement of how far the wheel axle moves in a vertical or near-vertical plane as the . For this article, we wont cover the kinematics of impact absorption in detail. The Commencal Meta TR uses a single pivot with the four linkages. | Image source: cannondale.com. Mountain Bike Suspension Basics: What to Know - BikeExchange When the cassette lifts, it tugs on the chain, causing chain growth and rotating the chainring backward. Continue reading and well give you a rundown of the basics and then discuss how bikes are constantly evolving, and with that, blending the different types of mountain bikes and mountain bike disciplines.
