Shocks & Tires: let's talk about air

Hey Divas!

Now that the dirt season is here, it's good to take a look at the suspension on your mountain bikes and dial things in for better control and comfort when riding over the rocks and roots we find on the trails.

This description and video from Liv say it pretty well. Notice that it takes playing with the controls on your rear shock and your fork to know what they actually do. Also, note that your shock may have different labels for the controls than those used in the examples. If in doubt, ask your bike mechanic if they can offer tips on doing this yourself.

If we have enough interest, we may add a suspension tuning clinic to the schedule, so keep that in mind.

Another way to improve the quality of your ride is to change your tire pressure. Lots of Divas have heard me say “lower your pressure for the dirt” and asked “how much?” That depends on the trail, and it depends on your tires and wheels. On a hard-packed trail with not many roots, you can ride with a bit more air pressure, but when you're on a bumpier trail, less pressure will help.

Think of your tires like a basketball: When pumped up high, both bounce really well! And firm tires are great on the road, but when riding on roots and rocks, firm tires mean they are bouncing off each protrusion, giving you less control as those tires leave the ground. You'll also feel more beat up from the rough trail. These are signs that you should lower your pressure. But, how much?

The amount of tire pressure you use will depend on the size of your rims and tires, whether you are running tubeless tires, and how much you weigh. The sidewalls of your tires will give you a starting point by listing the recommended inflation range (such as 30 - 60 psi), but that highest number is usually reserved for pavement. The range 20 - 40 psi is a better starting point for our dirt trails with the lower range for lighter riders on tubeless. Remember, if you start on the high side and make adjustments on the trail, you should find the perfect air pressure. Then check the pressure with a gauge when you finish riding so you know what worked for those trail conditions.

You should also remember to check your tire pressure before each ride because your tires will naturally continue to lose air. You don't want to start the ride too low and risk a flat!

Don't be afraid to adjust your suspension or tire pressure to get a better quality ride. And don't forget to carry a tire pump and spare inner tube (and maybe a shock pump) in case you need more air later in the ride. Now get out and ride this weekend!
