Five easy xes every rider should
know
We know not everybody is mechanically inclined … but every rider should
master these ve basic skills. We cover the highlights below, but if you
need a little deeper dive, you’ll nd how-to videos on the Trek Bike YouTube
channel: youtube.com/user/trekbikesusa.
1. Check your tires
Properly inated tires make for an enjoy-
able ride. Checking your tires for ination
and wear is your rst step to improve your
bicycle’s performance.
Check your tire pressure
Use a tire gauge, or a pump equipped with
a gauge, to check your tire pressure.
Inate (or deate) your tires
Use a hand pump to inate your tires to
the air pressure recommended on the
sidewall of the tire or to the pressure
recommended for the rim, whichever is
lower. Make sure your pump is suitable for
your valve.
Schrader Presta
With a Presta valve, you must loosen the
top valve before trying to inate the tire.
Do not over-inate your tires. If your tire is
over the recommended range, release air
and recheck the pressure.
NOTE: It is better to use a hand or foot
pump than a service station pump or elec-
tric compressor. The latter is more likely
to allow for over-ination, which can cause
the tire to blow out.
