We know, there’s no such thing as a stupid question. But there are some questions you might not want to ask your local shop or riding buddies. AASQ is our weekly series where we get to the bottom of your questions – serious or otherwise. This one deals with suspension performance for lightweight riders.
As a relatively lightweight rider myself (58.5 kg, ~129 lbs), I’m always told that suspension performance is poor for light riders. Generally speaking, while aftermarket shocks may be tuned appropriately for the bike they are fitted to, that tune is aimed at riders of average weight. Does this mean that performance is actually really bad for light riders, and if so, what can we do to improve it?
Never fear. We put this question to the experts from SR Suntour, Cane Creek, FOX, and the guys at their UK tuning center, Silverfish. We find out how rider weight really impacts suspension, and how the big brands tune their suspension products to suit the lighter rider.
I hear that, off-the-shelf, suspension performance is poorer for very light riders as compared riders of average weight or heavier. Is there some truth in this and if so, what sort of tune would you recommend to improve performance? To keep this simple, let’s assume the rider is an experienced rider who handles a bike well, and is able to ride fairly “aggressively” on all terrain.
Jordi Cortes, FOX: It’s absolutely true that lighter riders will have a tougher time setting up suspension. On the hydraulic side (damping) most suspension is designed around an average rider weight, say 170 lbs. While we do our best to offer a range of adjustability, someone on either extreme isn’t going to have the same experience as someone in the target weight range.
For top level riders this isn’t as big a deal as beginner or intermediate riders, since they tend to be fitter, stronger and faster so in turn are able to ride a firmer setup than your weekend rider.

While re-valving suspension can offer some benefits, very light riders will always feel the effects of friction to a greater extent than heavy riders. No matter your weight you have the same amount of seals and bushings as a heavy rider and the force to overcome this will be relatively higher compared to your body weight.

At this point we’ve only discussed suspension but there are other factors as well. Smaller riders tend to run narrower handlebars which basically makes the bar stiffer and increases feedback. Wheels also tend to be built to a certain stiffness which again would increase vibration.
Tim Williams, Silverfish: An optimal rebound damping tune is determined by the air pressure (or coil spring rate) which is in turn determined by the rider weight and bike design. The rebound damping is required to control the speed the shock returns after compression. Energy is stored in the spring under compression – when rebounding, this energy is being released and requires controlling with rebound damping.
