Tips
On cable brakes don’t make excessive adjustments at the lever’s barrel
adjuster, set the brake up correctly and use the barrel adjuster for fine tuning
Stems come in various lengths and rises so fit one that suits your riding
position.
1. Install bars
Most stems are front loaders so bar fitting is relatively easy, yet it’s
important to ensure all the bolts on the front clamp are tightened to an even
torque and there’s an equal gap between the top and bottom edge of the clamp and
stem body. Grease the stem bolts before fastening. Make sure the bars are
centred to the clamp and positioned at an angle you’re comfortable with. There’s
no need to over tighten. Around 5-7 Nm is sufficient for most stems.
2. Brake levers
Ensure the stem is true to the front wheel before going any further. Loosen the
brake levers and shifters so they can move freely on the bar. Sit on the bike,
move the brake lever inboard or out so your first two fingers can comfortably
reach and operate the lever. Adjust the angle so an imaginary straight line runs
from your shoulder, hand and through to you’re finger tips (see above picture).
This is the angle you should set the brake levers.
3. Lever reach
Most levers are designed so you can operate the brakes with two fingers. Sit on
the bike and squeeze the levers. Ideally the brake should engage when the bend
in your knuckles is at 90?. For cable brakes make adjustments at the barrel
adjuster until you achieve this angle. The lever reach can usually be adjusted
using the grub screw located in the lever body. Turning clockwise will move the
lever toward the bar, anticlockwise away from the bar.
4. Shifter position
Loosen the shifters and move them into a position that that feels natural. The
levers should be set so the gears can be operated without having to move your
hands off the bar. Once you’re happy fasten the shifters in place. Try to avoid
over doing the tightness of the brake levers and shifters. Ideally you want them
to move in the event of a crash to avoid damaging them.
5. End plugs
Ensure the ends of the bars are fitted with end plugs. These prevent the ends of
the bars getting damaged in the event of a crash. But more importantly they
protect your body. If left out the open end of a bar can quite easily take
chucks out of your body if you were to fall on the exposed end.
Most races in any discipline [XC, DH, 4X] now wont let you compete without bar
end plugs
6. Replacing grips
Remove old grips by either cutting them off with a sharp knife (taking care) or
by sliding a thin screwdriver or spoke between grip and bar. Then spray in some
WD40 to ease the old grips off the bar. Once removed fit end plugs before
installing the grips. Touch up paint or lacquer is the best way to secure
