    When is it best time to replace bike chain to prevent any cassette damage?

    Today I checked bike chain stretch is at 0.75. So should I replace the chain now? To avoid cassette damage or wait for 1.00. I don't want to replace the cassette at the same time as this will be quite expensive for me. I've only done around 900 miles on this chain, meaning that I would have to...

    Hi all, I have a bike that's done roughly 4000km in 2 years. I’m about to change out the chainrings and cassette which seem to have plenty of life left in them, I'm just switching out for some lower gears. Having checked my chain with a chain checker tool it’s not worn enough to require...

    Why a worn cassette cannot damage a new chain

    In the light of constant misrepresentation of the effects of a worn cassette on a new chain, I thought I'd explain why a new chain cannot be damaged by a worn cassette. We've seen this stated here as gospel often, and again, this week. Firstly, we need to understand why a chain wears and what...

    Removing a fixie cog without a chain whip - good trick!

    New Cassette movement

    Changed my cassette today from a 9 speed to 11-46t ms8 sunrace. After installation and tightening down the lock ring well, there is still slight movement in the cassette. Is that normal? The wheel bearings seem fine. I’m not sure what I can have done wrong. Any help appreciated.

    How many miles before changing chain and Cassette?

    I did about 700 miles on a chain and found it needed replacing. The guy at Halfords told me that the cassette would need replacing on the 3rd chain change. So does this mean the cassette would need changing every 2100 miles? I'm also curious as to why my chain is wearing out at 700 miles on my...

    in the process of building a recumbent trike for touring - initially was going for a rohloff speed hub but then chatting with a friend last night he's saying that i'd be better off with sram/shimano 11/12 speed rear and have a greater range of gears - i know the rohloffs are reliable and low...

    Cassette Making Weird Noise

    Hi all Today I noticed that my cassette was making a weird noise when I spin it. The noise is not noticeable when riding the bike I don't think and it is not causing loss of speed. It sounds like sand or maybe grit somewhere but I am just guessing. I cleaned my whole bike today and the...

    Cassette change

    I have a Cube Peloton with a granny gear of 30/32 which is the best of my three bikes but, not being a born climber, is it worth changing the cassette to a 34 teeth ? Would it really make a lot of difference when going up steep hills? I would appreciate your valued opinion on that.

    Is this cassette knackered?

    This is off my Dahon Vybe C7A folder. The chain was at the 1/16 wear limit so I changed it. I did notice the old chain skipped a bit in top gear under heavy power. However the new chain does it a lot more. So I took a closer look at the cassette (actually a free wheel) and top gear looks to be a...
