DISC BRAKES
Your bike is fied with a front disc brake, and the components should already be aached.
However, please check all connecons before aempng to ride the bicycle. Secure ghtly
the 6 bolts that hold the disc to the front wheel hub and the 2 bolts that hold the brake
mechanism to the fork. Double check that the front hub is inserted into the fork drop outs
correctly and that the quick release is closed and secure.
DISC GETS HOT! Severe injury could result from contact with the hot disc! Mind
your legs, as well as your hands.
If your bike is equipped with a front disc brake, be careful not to damage the
disc, caliper or brake pads when re-inserng the disc into the caliper. Never
acvate a disc brake’s control lever unless the disc is correctly inserted in the
caliper.
These brakes require breaking in! Ride and use the brakes gently for a few miles
before using the brakes in downhill condions, for sudden stops, or any other
serious braking. Please be aware that your brake system will change in
performance throughout the wear-in process. The disc brake should be cleaned
before the first ride using rubbing alcohol. NEVER use oil or similar products to
clean your disc brake system.
FRONT WHEEL
1. Locate the quick release skewer from the small parts carton of your bicycle.
2. Unscrew the lock nut from the quick release skewer, remove outer spring and slide the
skewer through the front wheel axle.
3. Install spring and then start to thread the lock nut back onto the skewer, but do not
ghten too far.
4. Slide the wheel into the fork wheel slots and be sure that the wheel is centered. Your
front wheel has a disc brake, insert the disc rotor into the slot on the caliper body as
you insert the wheel axle into the fork drop out.
5. The handle on the quick release has an “open” and a “closed” posion. Move the
handle so it is in the “open” posion. With one hand on the handle and one hand on
the lock nut, start to hand ghten the lock nut unl you start to feel some resistance
with the fork.
6. Try to close the handle. If it closes easily, open it up, and ghten the lock nut further. If
it is too difficult to close, open the handle, and loosen the lock nut try again.
7. The quick release handle should be difficult to push closed with your palm, but should
be possible. Pracce opening and closing the handle unl you feel comfortable. DO NOT
aempt to ghten the wheel by turning the handle to ghten; the handle is for securing
the wheel, use the lock nut for adjusng tension.
All quick release levers should be inspected before every ride to be sure they are
fully closed and secure. Failure to properly close the quick release lever can cause
loss of control of the bicycle resulng in injury or death.
Make sure the wheel is properly seated and the quick release is properly closed.

Shi both shiers to the smallest number indicated and place the chain on the
corresponding cog and chainring. Disconnect the front derailleur cable from the cable
anchor bolt. Check the posion of the front derailleur; it should be parallel with the outer
chainring and clear the largest chainring by 1-3mm whenfully engaged. With the chain on
the smallest chainring in front and the largest cog in back, adjust the Low limit screw so
the chain is centered in teh front derailleur cage. Reconnect the cable, pull any slack out,
and ghten the anchor bolt securely. Shi the font shier to the largest chainring. If the
chain does not go onto the largest chainring, turn the high limit screw in 1/4 turn
increments counter-clockwise unl the chain engages the largest chainring. If the chain
falls off the largest chainring, and into the pedals, adjust the HIGH limit screw in 1/4 turn
increments clockwise unl the chain no longer falls off. Shi through every gear, using the
barrel adjusters to fine tune each transion. The barrel adjuster for the front derailleur is
located on the front shier where the cable comes out of the shier. Clockwise loosens
