How do I know if I have set my preload correctly on my mountain bike forks? |
How do I know if I have set my preload correctly on my mountain bike forks? When setting up your suspension, there are a couple of things to look for. 1st, You need to know how much total travel your fork has. When you sit on your bike in your normal riding position, the fork should compress anywhere from 10 to 20 percent of the total travel. This is known as "Sag". If there's too little sag, then decrease the preload. Conversely, if there's too much sag, increase preload. Second thing to check is how the fork works when you are actually riding. When out on your typical trail and riding in your normal manner, try to pay attention to how much fork travel is used up when you hit the hardest or biggest bump (or drop) on the trail. If the fork bottoms out lightly, that's OK and lets you know that you are using all of the available travel. But if the fork bottoms very hard, or on many different bumps, then the preload or spring rate is too light and needs to be stiffened up a bit either by adjusting preload or changing to stiffer springs (if you use an air fork, simply increase the air pressure). If you are not sure how much fork travel is being used while riding, put a zip tie around one of the upper fork legs, and slide it down so it rests against the top of the lower leg. When you ride the bike over bumps, the zip tie will move upwards as the fork compresses. This will indicate very accurately how much of the travel is being used and can be a guide in setting preload. Hope this helps. Source(s): My own experience. check the spoons and knives, then you can deal with the forks |
