What tools do I need to remove a bike cassette?
The lockring is designed to hold the cogs of the cassette in place on the hub. In order to remove and replace your cassette, you need to unscrew this lockring. You’ll need three tools to do this: a chain whip, a cassette lockring remover and a large adjustable crescent wrench.
When should I change my bike cassette?
My rule of thumb is to replace it at 75 per cent wear (as measured with a chain-wear indicator). If you stick with this guideline, your cassette and chainrings will last a lot longer. A cassette, in most cases, can last for approximately two to three chain replacements if they are done at the right time.
What can I use if I don’t have a chain whip?
If you have a regular claw hammer and another length of chain, then you can create your own chain whip. Just drape the length of chain through the claw part of the hammer with the majority of chain going away from the handle of the hammer.
What type of cassette do I have?
To determine if a sprocket is a freewheel or cassette system, remove the rear wheel from the bike. Find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub.
Should my rear cassette wobble?
A slight wobble is not uncommon. Certainly not all cassettes wobble but some do and are still within specs. It’s impossible to build the quantity of cassettes that Shimano and SRAM do without some variance in tolerances.
How much does it cost to replace a bike cassette?
The cost to replace a cassette or freewheel can range anywhere from $25 to upwards of $300 on high end bikes and chainrings can run anywhere from around $40 to $250 on high end bikes.
