For the intermediate mechanic:
Most pedals can be installed with an Allen wrench rather than
the old-school 15-millimeter pedal wrench.
Check the backside of the pedal axle, which is where you’ll find
the spot for the Allen wrench.
Pedals don’t need a huge amount of torque. The amount you
can generate with the Allen wrench will be plenty.
Always remember that the left- and right-side pedals are
threaded differently, so the old adage of “righty tighty, lefty
loosey” doesn’t work here. Instead, remember to tighten the
pedals and rotate toward the front of the bike. To loosen them,
rotate toward the back.
Removing and reinstalling a cassette is necessary whenever you
want to swap wheels or just give your bike a deep-down clean.
The necessary tools are a chain whip, cassette lockring tool, and
either a ratchet driver or crescent wrench that fits the lockring
The chain whip is designed to keep the cassette from doing what
it does naturally—spin freely—while you’re removing the lockring.
We like to put the length of chain on the second largest cog like
this. It will give you a ton of leverage, and since the links on the
chain whip are all engaged, it will prevent the tool from popping
off in the process.
