Cheers for the input. Fair point re: custom wheels – my current wheels are C K hubs with Stans Flow rims on DT Supercomp which come in at around the same weight as the DT 1750’s and the 09 SX’s, but not as light as the Rovals. C K and Pro II’s are about the same weight but obviously cheaper. Having a couple of sets means whilst the availability of parts for factory wheels is a good point, I’ll always have a second set to fall back on.
My original aim was to learn to build my own, but got really annoyed that it would cost more to buy the parts and build myself than to buy a pair custom-built! I’m still keen to learn, so am keeping an eye out for 2nd hand bits.
i9’s could be interesting, problem is that limited distributors (think it’s just riding along that are the only stockists) means limited discounting, making them pretty expensive compared to other options.
Looks like vote is for Roval or Mavic SX’s.
