After a few issues shifting into big ring and a little chain-suck during my last race I thought perhaps that , even though the current chain hasn't done that much, I ought to replace it before things got too worn, forcing wholesale replacement of the complete drive train.
A quick test ride on the chase has left me in a quandry. I'm getting a little bit of jumping on one cog at the back. Not much, and not on a gear I use that much but still annoying. The alternative £50 on yet another cassette, and the big ring at the front is a bit worn, where to stop? particularly with at least 3 months of winter racing before the international season gets going properly when the bike needs to be in perfect condition..
I think Ill just put up with it and replace the whole lot in March, when I put the bow on a bit of a diet!


hmm … sounds like a major issue. I need a new rear derailleur and ended up looking at Sram XX groupets … Its a neverending story when it comes to bikes!!!
