Tech

It's important to your safety, performance and enjoyment to understand how things work on your bicycle. We
urge you to ask your dealer how to do the things described in this section before you attempt them yourself, and
that you have your dealer check your work before you ride the bike. If you have even the slightest doubt as to
whether you understand something in this section of the Manual, talk to your dealer. See also Appendix A, B, C
and D.
A. Wheels
Bicycle wheels are designed to be removable for easier transportation and for repair of a tire puncture. In
most cases, the wheel axles are inserted into slots, called "dropouts" in the fork and frame, but some suspension
mountain bikes use what is called a "through axle" wheel mounting system.
NOTE: If you have a mountain bike equipped with through axle front or rear wheels, make sure that your
dealer has given you the manufacturer's instructions, and follow those when installing or removing a
through axle wheel. If you don't know what a through axle is, ask your dealer.
Wheels are secured in one of three ways:
• A hollow axle with a shaft ("skewer") running through it which has an adjustable tension nut on one end and an
over-center cam on the other (named cam action system or Quick Release System). (Fig.8 a & b)
• A hollow axle with a shaft ("skewer") running through it which has a nut on one end and a fitting for a hex key,
lock lever or other tightening device on the other (through bolt). (Fig 9)
• Hex nuts or hex key bolts which are threaded on to or into the hub axle (bolt-on wheel). (Fig 10)
Your bicycle may be equipped with a different securing method for the front wheel than for the rear wheel.
Discuss the wheel securing method for your bicycle with your dealer.
It is very important that you understand the type of wheel securing method on your bicycle, that you
know how to secure the wheels correctly, and that you know how to apply the correct clamping force
that safely secures the wheel. Ask your dealer to instruct you in correct wheel removal and installation,
and ask him to give you any available manufacturer's instructions.
WARNING: Riding with an improperly secured wheel can allow the wheel to wobble or fall off the
bicycle, which can cause serious injury or death. Therefore, it is essential that you:
1. Ask your dealer to help you make sure you know how to install and remove your wheels safely.
