Cogset R&R

Sun, 09 Mar 2008 09:46:08 -0700

Remove and replace a cogset. In this example, we are using a Shimano LX 34x11t cogset on a Mavic SpeedCity rear wheel.

Tool list:

1. Shimano lock ring tool

2. Chain whip

3. Large Crescent wrench

4. Grease

torque: 40Nm

How to:

1. Remove rear wheel

2. Remove QR/Skewer

3. Place the corrrect Lock ring tool into place.

3. Hold cogset in place using chain whip.

4. Use large Crescent wrench to turn lock ring tool counter clockwise to loosen.

5. By hand, use lock ring tool, to finish the removal. Rotate counter clockwise.

6. Identify “landmark groove/spline”

a. this is the thin spline on the Freehub spline pattern.

b. Campy and Shimano patterns differ.

7. Try to remove all of the cogs in one unit.

a. if the cogset has a bunch of spacers, be mindful to remember the way they are stacked. that is...try to remember the sequence. Its easiest to just keep this all together, and not worry about it.

8. Wipe clean the Freehub, and reapply fresh new grease.

9. Install new cogset or clean up the old one, whatever...

10. By hand, install the lock ring.

a. If this is a new cogset, grease the threads of the lock ring.

11. Using the Crescent wrench tighten (clockwise) the lock ring.

12. Follow manufacturer’s torque specs.

a. In this case, I believe it states 40N-m on the lock ring itself.

13. Torque to spec.

How to change a flat

Fixing a flat is probably the most repeated mechanical repair the average cyclist will make. It can easy, and it can be frustrating. Once upon a time when I was all infatuated with racing, I sat and removed and replaced the tyre and tube, from the bike, over and over, until it was SYNAPTIC!
