droo Posted June 2, 2014 Share Link About halfway down the page there's a document called "everything you need to know about chains". It's a long read, but it does what it says on the box. Look for the bit about measuring chains to find out if your cassette needs replacing. Link to comment Share on other sites More sharing options...

David Marshall Posted June 2, 2014 Share When you put a new chain on the chain will slip by one tooth on the worn gears on the cassette (when powering hard). It can also slip on a worn chain ring but usually you pick up chain suck before this happens. Only change the cassette if the new chain slips. Check chain condition as per Droo's link.

Skylark Posted June 2, 2014 Share From those pics it all still looks pretty fresh and good to go, lbs love prematurely replacing the drivetrain, easy money.Just make sure you watch the wear on the chain and always replace it well within wear limits. I keep replacing the chain until the chain starts slipping on the cassette cogs or getting suck on the chainrings, when that happens on a new/within wear limits chain then you know the parts are finally toast.

kosmonooit Posted June 2, 2014 Share Looks okay to me.... You should always take the bikes shops advice to replace the cassette with the chain with a few table spoons of $alt. Front rings are generally Al, they wear more quickly and thats more obvious to see. Its important to keep the chain within the wear specs because if that goes out, that will cause uneven wear on the cassette and chain rings, because the pitch of the chain will change as it wears. Just my opinion of course, I am sure many disagree here. Edited June 2, 2014 by kosmonooit Dustbin Dog 1 Link to comment Share on other sites More sharing options...

Stretch Posted June 2, 2014 Share keep an eye on your chain wear..get an inch steel rule...pin to pin across 12 links a new chain will measure 12" if it is 1/16th of an inch over 12" replace the chain...if it is 1/8th of an inch it may be too late to change the chain but you could give it a bash...anything more and you may as well ride that chain out with your drive train Link to comment Share on other sites More sharing options...
CleatsnCleavage Posted June 2, 2014 Share My six month old full sus went to Cycle Factory for a "wash". When I fetch it this week I will post a picture of my old cassette (because of course the LBS now has me paying for a new chain, new cabling and gear housing, new cassette and new headset bearings). Look forward to hearing the Hub opinion. Link to comment Share on other sites More sharing options...
