Chain, chainring, cassette

ian220476

upgraded the whole drivetrain piece last year. Had no problems at all and having covered the best part of a years racing, the chain has now gone through the 0.75 measurement on the measure thingy. Time for a new chain

1. Any recommendations. Xt cranks; redwin cassette and currently a pc991 chain. very pleased with it but open to ideas.
2. Read somewhere that I should replace cassette and chainring when changing the chaine. Really????

Thx

If you change the chain before it 'stretches' too far, a new chain rarely causes problems. I like to buy cheap SRAM 951 and change them regularly.

KMC chain would be my choice

If you change the chain before it gets much past 1% stretch you should get away with not needing a new cassette.

KMC, take your pick

I use a KMX x9 chain with either an SLX or XT cassette.
They both wear at a similar speed (very very slow wear), so don't change until you get chain slip.

I use steel chain rings so they do not wear (well SO much slower that you can almost ignore it).

XT is one of the lightest and strongest cassettes, much better than anything SRAM do apart from xx.

990 cross step is a great chain (better than regular 990), but twice the price of X9 and wears faster.

The £40 Shimano tool? If not, then you are very likely measuring roller wear too, which is of no real consequence (search for articles by Sheldon Brown or Jobst Brandt on the subject). Try a ruler on the pins instead, you might be surprised.

On the basis that the late Sheldon Brown seemed to be correct on just about anything I could verify, I take his 12.0625" (0.52%) to be my chain wear limit.

Cheers everyone - relieved to hear it is a chain I need and not everything else as well.
