types of rear suspension mtb
Rear mountain bike suspension is a much more complex system than front suspension, as they rely on one or more pivots in the frame and linkages to connect the MTB rear shock and the rear wheel. Enlarge photo. ZWM3OTk0M2ZiNzE0NzA4ODU0NjU5NjA2NGQ2NWE0MmE3ZTVlOTllZjI3NTQx Is it a linkage-driven single pivot? MTY0MDhjNjJlZmJmY2ViOTY4NWY5MzlmNGRlYTU0MGU2OWNkNjc1N2M3N2Iz See our table for an explanation of the amount of travel and the corresponding type of bike. RetroRides K100 Cafe Racer - Return of the Cafe Racers 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. With a host of terms like four bar, faux bar, virtual pivot, multi . When it comes to mountain bike geekery, perhaps no other area of the bike contains such a deep and mystifying vocabulary as the suspension. Because anti-squat depends on chain tension, the anti-squat percentage is different in each gear on the cassette or if you have multiple chainrings. Retest the sag and repeat the process if necessary. At the top end, hardtails are made from carbon fiber and designed for racing. Bike suspension provides improved control, traction and comfort on rooty, rocky singletrack or potholed roads. Freeride is another example. Basic Mountain Bike Suspension Designs, Explained If you dont have enough, bleed some air. So you can better understand how rear mountain bike suspension shocks work, weve labeled this Fox Float DPX2 air shock. The disadvantage of a single pivot design is a linear leverage ratio, meaning that if X amount of pressure results in Y amount of suspension compression, 2X will result in 2Y. For most air suspension, the shaft of the shock or fork will likely have numbers listed in percentages so you can adjust the air pressure to achieve correct sag, by adding or removing air in small increments using a shock pump. Head-tube angle is the angle that the head tube forms with the ground. If you use more travel than you want to, your suspension is probably too soft. Repeat the same pumping or bleeding process as required to reach your targetted sag, and note the air pressure. Anti-rise is the effect of braking forces on the suspension or how much the suspension compresses or extends from braking. Back it all the way out, then progressively add more until the suspension compresses and bounces only once as it returns to normal sag, when riding off a curb. 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). They are used for races that feature a lot of climbing or smoother trails. The diameter of the stanchion tubes affects this lateral stiffness. A mountain bike with both front fork and rear shock suspension is called a full-suspension, or dual suspension. High pivot is another unique design that brands like Cannondale (Jekyll), Norco (Shore), and Devinci (Spartan) are using on select models. Learn how to choose the best carrier for your car. Mountain Bike Suspension Basics: What to Know, Aero vs Endurance vs Lightweight Road Bikes Explained, How to Use Geometry Charts and What They Mean, Factors to Consider When Buying a Bike Rack, Mixed terrain, including more trail features but still lots of pedalling, Gravity based trails, bigger drops, rugged root or rock gardens, Steep, rough technical gravity trails, large rocks, drops and jumps. An air spring is a pressurized air chamber. If yours doesnt have any, you must measure the distance to the ring and calculate it as a percentage of the total travel (usually indicated on the shock or fork). Downcountry bikes sit around 120mm of travel and get specced with components that increase descending capability such as tougher tires and longer dropper posts. Alternatively, you can design Horst-link suspension to have high anti-squat at the beginning of the stroke and less at the end. NWZjNGQ1ODAwMWJmYjEyMTc4NWU3YjMwZGM3MWVlOWIyNTJlYjc1MTkzMjIy High pivot suspension has a more rearward axle path, improving impact absorption and increasing pedaling efficiency. Ideally, you want anti-squat to peak in the early to mid part of the travel and then drop off, which systems like Santa Cruzs VPP achieve. Fire motorcycle - Wikipedia Repeat this single explosive bounce, but focus on the rear shock this time. 1996 - 2023 Bikexchange.com: Cycling Guides & Bicycle Reviews. YzI2Nzk0NjA5OTAyYWYyNjA2YjhmMjFjMjMyYzFiMjRhOGE5MDhlNDM3N2U0 This essentially gives the option to turn the suspension on and off, or provide some level between. The spring provides resistance to the wheels movement when it hits an obstacle (compression) and the energy to move back down after compressing (rebound). Hardware: Refers to the components used to mount the rear shock in the frame (via the eyelet bushing). These bikes are extremely lightweight and efficient. If you dont use enough travel, you could remove a volume spacer or set a slightly higher sag. Suspension quality has a major impact on its price. The seat stays and chain stays in a full suspension bike are part of the rear suspension linkages. 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. From hardtails to full-suspension bikes, this is our guide to the different types of mountain bikes and what they're intended to do. At REI, we believe that a life outdoors is a life well lived. Complete Mountain Bike Suspension Guide: Basic Terms and Setup Ryan eventually gravitated toward enduro and downhill racing but has also been found in the occasional road and cyclo-cross events. Too much pressure and the suspension will not be active to critical hits and will ride harshly while offering poor traction. Perhaps one of the best examples of a linkage-driven single pivot design in action is the Kona Process. YzA4MmVjZmJiZDY3OTAwZjExZTM2YzcyZGQwNDMyNmU2NmNlMWU0NWFiYzhh However, there is more drivetrain drag, extra mechanical complexity and maintenance, and the geometry varies through the travel. We've been sharing our passion for the outdoors since 1938. There arent necessarily freeride-specific bikes, with riders choosing the bike that best fits their needs.

Twin-link suspension is highly tunable, like four-bar suspension, but the curves arent as predictable. Pinkbike Poll: What's Your Favorite MTB Suspension Design? Buyer's Guide To Mountain Bike Suspension, Part 1 - BikeRadar. Hardtails are great for riders who enjoy off-road riding but don't tackle the most technical and rough trails. Sit on the bike and start rolling. Hardtails do not have a rear shock and have either a suspension fork or a rigid fork. NTA2OTgwMWVjZDAyNDE4YWRlNWE5NmVjZDg4NTUwYzA0NzUyZTZhNWMwNTQ2 The closest design to the single pivot configuration is a linkage-driven version. The following instructions include the most important initial adjustments. Fox suspension has the air-pressure valve located on the top of the crown. Best MTB Gear | In the twin-link design, either the rear swingarm or one of the rocker links will drive the shock. Play or knocking between the stanchions and the lower sliders. Enter your email for the top stories in mountain biking, plus product picks and deals delivered to your inbox each week. Interestingly, the first rear suspension MTBs actually used forks in the rear dropout, but this was an ineffective design and was quickly discontinued. Linkages, shown in green, are used to connect to the shock. The shock allows the rear wheel to soak up impacts, helping to keep the tire in contact with the ground, increasing rider control and decreasing rider fatigue. It comes from the tension in the chain that pulls the swingarm back down when the shock compresses and the rear wheel lifts. Single pivot design examples include the Orange Five and even the latest Specialized Epic. Downcountry bikes, like the Specialized Epic Evo or Cannondale Scalpel SE, feature slacker geometry than traditional cross-country race bikes to make them all-rounder trail rippers that blend XC race bikes and trail bikes. Anyone can join and everyone belongs. A fork designed to handle harder and faster hits needs wider, stiffer stanchions to ensure they dont flex too much and cause damage. NTg4ZTQ1MzhjMzdkMjIzMmY1Y2YwYTM1ZDc4YTI3NWM0NzNiZTY3MzI1NDc0 If your coil spring feels too soft or too firm for your weight and riding styleand the available adjustments have not corrected the issueyour bike shop may be able to replace your current springs with a softer or firmer version (if one is available for the model).

MzQ4N2IwNmYzMTFiOTZkMTkyZjFiYjc1NmM4ZjJkNzJlMDljYTNiZWE1MmE4 For more conservative riding or inexperienced riders, aim for more sag. Though if the trail bikes of yesteryear were masters of none, technological advancements have made them masters of a lot. Also, more expensive suspension components are built to higher standards and often with more complex designs, so not only are tolerances tighter and parts smoother, but often the function is more advanced. However, instead of connecting directly, the swingarm uses linkages to connect to the shock. Typical specs: 120-140mm of suspension travel; 67-69 head-tube angle. Both of these four-bar iterations connect a rigid rear triangle to the main frame with a linkage. OGE4NDRiNGI5OWI3OTk4YTZjYjUxNDNlODIyMmU2MmYzNjVlZjM4MWRmZjM5 Some will recommend a. -----END REPORT-----. 0% anti-rise means the suspension stays active and plush. Manufacturers can reduce pedal kickback by using an idler pulley like in the high-pivot system. Mountain bike axle standards: the complete guide - BikeRadar We then go on to provide a more detailed look at how suspension works. Note: Bicycle manufacturers dont make their own suspension products. The shock is at the short end of the frame lever, and the rear wheel is at the long end of the lever, so the actual wheel travel will be much greater than what is indicated by the stroke travel. Several countries around the world use fire vehicles based on a motorcycle, often for rapid intervention to beat traffic congestion, and the equipment carried ranges from simple extinguishers to jet guns with hose rigs. The best way to figure this out for yourself is to get to riding and follow the fun. Turn the rebound lever counter-clockwise one click and repeat this process until the wheel starts leaving the ground upon release. How will you know? Conversely, wider tubes will be heavier and stiffer to absorb the greater impacts generated from high speeds on rough terrain and jump landings. Use the end of a zip-tie and press it in past the seals to release this pressure. Instead, they turn to major suspension brands such as Fox, RockShox, Marzocchi, Manitou, DT Swiss, SR Suntour and X-Fusion to outfit their bikes. The all-mountain term is not as common anymore however it is usually used to describe a bike with between 140mm and 160mm of travel. There is beauty in the variety of mountain bikes. Shock: Rear suspension unit. An air-sprung unit not holding air and losing all travel. 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. Best Bike Trails | Recommendations for sag depend on the discipline and the manufacturer. You can easily unsubscribe at any time. Mzc2Yzc2NWUyOWFlODQ4NGEyODRlODYxYWY3YjEwNDQ4YTQyNjAxZTczMDgy The shock is contained within a pivot system, which uses linkages to allow the shock to move within the frame. Thanks for this. That means they can ride anything from dirt roads to singletrack, but they will struggle when the trails get more technical. Pedal bob is an oscillating motion that occurs when you push the pedals. The surging trend of downcountry bikes takes the efficiency of an XC race bike but compromises the all-out lightweight by adding a little more capability. Adjusting damping settings are referred to as tuning the fork. Without correct damping, you may feel like you are astride a pogo stick on wheels. Different types of mountain biking For example, manufacturers could select a stroke progression thats softer at the start, providing better small bump sensitivity. How much suspension travel do I need on my mountain bike? In addition, factors like the riders center of gravity and where the shock is in its travel will contribute to the actual anti-squat in a given moment. When cleaning suspension, wipe around the seals and stanchion with a clean microfiber rag. It can be hard to tell. If youre unsure, err on the side of caution and set it so the fork returns slightly faster than the MTB rear shock. Suspension set up is deserving a whole other article, so stay tuned later in the series for our guide to setting up your suspension. A Downhill bike naturally has front and rear suspension (Fully), with the largest suspension travel of all mountain bikes types (170 - 210 mm). 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. No matter which bike you ride, how much you spend on it, or what the manufacturers try to tell you, a suspension platform is a compromise. The wheel path is a set path that the axle follows when there is an impact on the rear wheel. The fork uses a slightly different process (this works for hardtail bikes). Carbon will be the lightest and steel will be the heaviest. Widgets, Explore England and Wales company registration number 2008885. This swingarm rotates around this pivot with a fixed instant center throughout the travel. A basic suspension setup can help you get onto the trails quickly after buying a new bike. You might hear these referred to as full-sus or duallies in mountain bike vernacular. Plus, sites like this one constantly writing about terms like enduro and cross-country can make things confusing. Lighter and more efficient than a full suspension Much more comfortable than a rigid MTB Best all-rounder mountain bike Good climbing capabilities CONS: Cheap hardtail mountain bikes have poor performance On rough terrain, a hardtail mountain bike is not as comfortable as the full suspension Sit onto the saddle slowly, and allow your weight to press down with your feet off the ground. Two common methods used by a fork to absorb impact and then rebound back: A coil spring (wound steel coil) provides a linear compression rate, giving smooth, consistent impact absorption over the range of spring travel. ZDBjNGRmOGRkZWJkOTBiMDVlZWZmNzc2MjU0OGQ1OGI4MTAwNTY3Mzk4YzRi Air pressure: An air-sprung fork does not have a preload knob; instead it has a Schrader valve for adjusting the air pressure, and therefore firmness, of the fork. Mountain bike rear shocks consist of two telescopic tubes that slide into each other. Your Honda NSR resource on the web! The most advanced suspension designs can maximize pedaling efficiency in the early part of the travel, where its most important, and let it digress throughout the travel. Benefits include great gear offers, special pricing on events and an annual Co-op Member Rewardfor life. YzEwMzY0MTMzMzdhODlhZTJiZmRiOWNlZWRhZDA4N2Y1OTA1M2FjZWQ5OTM3 Anybody whos stepped foot in a bike shop or pulled up to a trailhead knows that there is an abundance of different types of mountain bikes out there. Push the ring on the fork stanchion to the bottom. The swingarm is shown in red. 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). Travel This refers to the amount of distance the suspension will move before it is fully compressed. Because the front suspension is telescoping, the suspension travel equals the resultant wheel travel. MTB styles and disciplines: Guide to 16 different types of - AWE365 Rebound controls how fast the shock returns after compressionan appropriate rebound setting balances sensitivity and traction. Lets take a brief look at two of the most popular. 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. -----BEGIN REPORT----- NGI2NzcxNjVjMjMxMmQzODZiYzljZmVkYmI5OWQzYzkyZjM2MzIxN2Q3Y2E1 Forks with less than 100mm travel are typically only for hybrids or kids MTBs. In addition, there is no patent on the design, so that any manufacturer can use it. The Horst-link design was created and patented by Horst Leitner, although other companies have bought the right to use it. Dismount and note the position of the ring. ZjM0YmFhYzY3NGVkNzcwOWZhZWU3ZDAzZWU4YjcyMWY2ZmExZWRjYTE3NmU1 Youll find a range of options and prices. Rides: Santa Cruz Hightower, Specialized Tarmac SL4, Cotic FlareMax5 review short travel steel with 5 star feel, Deviate Cycles continue their high pivot Scottish revolution with the Highlander 2. Add a volume spacer or set a lower sag percentage to address this. Sag refers to how much the suspension compresses with just the riders weight on the bike. This interplay is particularly relevant for full-suspension bikes. Trail bikes are perhaps the broadest category of mountain bikes, but they range from 130 to 150mm of suspension travel.
