    Looking for replacement cassette suggestions.

    After fitting a new chain (first ever chain change) as it approach (but hadn't yet reached 0.75) I was very suprised to find the new chan slipping all over the place on the old cassette. Alas I need a new one. The cassette on the bike (factory) is Microshift CS-H092 9V 11/32 cassette...

    Looking to replace cassette, but I'm not sure what these number mean?

    I'm looking to replace my cassette, but I'm struggling to know which on to get for my bike. I have a Sram PG 850 8 speed cassette, but I now see there are a choice of five of these cassettes on amazon and they all look the same apart from a number. These are the numbers 11-28t, 11-30t, 11-32t...

    Help: Shimano cassette question

    Hi guys and gals, I would like to know if Shimano HG50 9 Speed Cassette 13-25 would be a direct replacement for a 12-25 HG50 cassette? Assuming it's just a minor difference on the gearing and it should fit my PR2 wheelset fine? My PR2 wheelset had a 10 speed tiagra cassette on it but I...

    Cassette cleaning

    I had the pleasure of cleaning my son in laws bike. He had a new chain for it and the cassette was black with muck. I find white spirit is ideal but didn't have any. So I dissolved a dishwasher tab in boiling water and left a few minutes. Scrubbed each cog for a few seconds and job done. Now...

    Freewheel vs cassette

    Today, I have removed the freewheel from my touring bike as I wanted to service the dirty hub, cogs, spokes etc. It was shocking to see how easy the process was. I have used a long braker bar and the £4 special tool for removing the freewheel. You don't disturb any other parts and it takes not...

    CS-HG30-8I cassette - what do I need as a replacement? When to replace?

    I have a bike with a 11-32 Cassette, and Shimano Tourney groupset. When replacing the cassette, do I need to keep to the same size (11-32), same make (Shimano) or are they interchangeable (doesnt changing the ratio - affect chain length). Current Cassette is marked CS-HG30-8I. What do I need to...

    Changing cassette advice

    Hi, I have just took delivery of my new bike but I am planning on upgrading the wheels soon. Also at the same time I am thinking of swapping the cassette. At the moment I have 50/34 and an 11-34 rear, I thought this might have been a bit easy on the gearing, and although the 1-1 gear is quite...

    I have just put a different rear wheel in my bike and unfortunately the 11 cog was catching the inside of the chain stay slightly. It has cut through the lacquer and marked the carbon. There is a little bit of a ridge where it has rubbed. I assume the carbon will be fairly thick at this point...

    Worn chain or cassette? Any advice?

    I've got a 6-7 year old MTB ex Halfords Voodoo with light to medium use and well maintained, used on flat trails. I'm now losing the chain on every ride. I don't know if its down to a worn cassette or chain or both. I've cleaned it up and lubed it with silicone lube, and adjusted the derailleur...

    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...

    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...
