I'm fairly new to all this and my year old rockhopper seemed due for some attention so thought I would have a play myself. I'm a little stuck and after a little advice.
Chain wear gauge was showing 0.75 but not quite 1.0 so thought I'd be good and get a new chain. It did take a while to get round to fitting and the old chain was now just fitting into the 1.0 wear gauge.
Problem came when it seemed that I just could not get the gear adjustment right on rear. Chain slips on smallest 2 cogs. Finally gave up and refitted old chain and that is not having the same problem. Have I taken it too far with the chain and now do I have to replace my cassette? Other options?
Cheers for any advice!
New cassette too 🙁
and check your front rings as well.
Yes & yes. You may also need front chainrings.
Other option is to run the current set into the ground. Then replace the lot.
So I really have to go for it on cassette replacement? Was hoping I was being good - at what point do you need to replace a chain to avoid cassette replacement?
I replaced large chainring recently (bashed on a rock or something) so I think chainring side OK (wear would have come from commute on big chainring and small cassette cogs so guess thats the reason for this.
Should I run into ground or replace now (cassette only 20 quid on chainreaction so....)
If you replace chain, if its pretty worn, then cassette and chainrings need to be replaced otherwise it won't mesh with new chain properly, as they all wear together. But you can get away without replacing a chainring if you haven't used it much
I'd say if you already have newish chainrings (most wear should be on the middle and inner tho) I'd try and keep them good. So replace the cassette - you already have the chain.
Apparently try and replace the chain at (or even slightly BEFORE) you can get the .75 end through a link. Once it gets over .75 and near 1% the chain wear will be killing everything.
Right, well at least I do know how to get my cassette off (been playing at servicing my rear hub as well recently). On to Wiggle or Chainreaction to order a new cassette then.
Also think I need a single speed for my London commute to stop killing my mtb.
Cheers for the advice.
