How to Rotafix (tighten/loosen) a Fixed Gear Cog without Chain Whip

How to Rotafix:

Rotafix is a technique for tightening or loosening a cog without a chain whip.

Why Roafix? Because standard chain whips do not fit 1/8” cogs, and you get the mechanical advantage of the entire wheel for tightening.

When performing a rotafix, wrap a rag around the bottom bracket shell to protect the paint on your frame from being damaged by the chain.

Steps for Removing an Adjustable Bottom Bracket

Remove an adjustable bottom bracket:

start by first removing the cranks. A lockring on the outside of the left hand side cup is an indication that the cup and cone bottom bracket is serviceable. Turn this counter clockwise to unlock the cup. This is easiest with a lockring spanner that fits the notches on the ring exactly. You can also use a universal tool with one tooth or tap it around with a hammer and an old screwdriver. Remove the lockring.

Spray down the area where you will be applying the decal first with the grease remover and wipe it down with a clean rag or towel. Using a microfiber rag is ideal because it doesn’t leave any lint behind.

The chain ring is the name for the ring the chain sits on in the front of the drivetrain or by the pedals. Every chainring has teeth on it, though the number of teeth on a given chain ring changes.

On the back of the drivetrain where the chain sits by the wheel, you have what is called a rear cog or sprocket. These will also have teeth on them.
