Why is setting sag on mountain bikes so important?
Modern MTB suspension setup is based on the bike sitting at a particular height and posture with the rider mounted, regardless of the weight of the rider. This means that every rider needs to measure the rider sag and adjust the spring preload or shock pressure so the bike handles properly. In some cases it may be necessary to get heavier or softer springs depending on the rider and riding style. It is critical to check sag regularly and adjust for different conditions. Even if you have no experience setting up MTB suspension, this sag tool makes it super fast and easy to make sure your bike is setup properly and keeps you fast, safe and having fun!
How often should I check my mountain bike's sag?
With mountain bikes, the manufacturers recommend checking it every ride and adjust to find the perfect setting for any given condition. Over time air bleeds from the suspension, springs settle in and the rider load changes so does the amount of sag. For faster conditions run a little extra sag for stability and for the tight stuff run a little less for better steering. Checking sag regularly can also reveal service issues early if you know your numbers.
Do I need to service my MTB suspension?
Yes, you should get the suspension serviced at least every 20-30 hours of riding. As the fluids break down and bushings and seals wear, the suspension will start to perform poorly. Also remember to grease any linkage, pivot points and shock mount points whenever you service the suspension.
