DE-GUNK YOUR SPROCKETS
Neil Holman reveals how to spruce up your sprockets
Cleaning your cassette is essential maintenance that needn’t be a chore
Lay Down The Law
Start by manually picking away hard mud, grass, gunk and clumps of grease. Remove the cassette body from the wheel if possible. You’ll need to use a strong degreaser so you don’t want it working its way into the freehub bearings. Have a couple of sheets of old newspaper or a large old cloth handy to carefully lay out the sprockets, lockring and spacers in order from left to right.
Degrease Is The Word
In a well-ventilated area place a very strong degreaser in a plastic tub, following the degreaser directions. Place each separate sprocket individually into the tub to give it a decent clean. If you have a cassette cluster that’s riveted together and there is a lot of crud encrusted in between the sprockets, use a cassette crud claw or even a thin, old screwdriver to chisel the worst of it out before you give the cassette its degreasing bath.
Fill a second tub with hot water and washing up liquid. Using a hard bristle brush or an old toothbrush give the sprockets a good scrub. Once thoroughly cleaned, use an old cloth to dry off the sprockets and spacers. Once that’s done refit them in the opposite order - from right to left - and torque the lockring to the recommended setting. It’s a little bit of effort to help prolong the life of one of your bike’s vital components.
