Seems like we are the only 2 here with this question! I was advised on other forums that a 10 speed chainset should work ok with 9 speed setup, although the shifting may a bit less smooth. Maybe it is worth contacting Evans or pay a visit to your local store to see if they have, or can obtain the 9 speed FSA Omega Chainset you need – the email I have had from FSA says the 10 speed version is not compatible, seems like they don’t have the 9 speed chainset available for anyone other than bike retailers/manufacturers which is ridiculous..
Thanks very much for this, nice to know someone had the same problem! I’ll try contacting Evans special orders again, last time even the customer services person I ended up speaking to couldn’t contact them as they were switching systems and told me to try again in a month, hopefully they might be ready now. If they don’t answer though I think I’ll go with the 10 speed FSA chainset so I don’t need to bother changing the bottom bracket too, and hope it’s OK. Feel such a pillock for breaking it in the first place, I only rode it about 5 times!
