Do you recall how "hilly" or rolling the course is?
One thing I've not thought about is gearing. My setup was last used for the Welsh course so it's 57x23 or 21 whatever the straight 11spd cassette is. I'm aiming for 25mph but I don't want to cross chain like a bastard on climbs like I was yesterday (on what I hope was a much lumpier road).
I think I might have a compatible 54T in my stash but it's not as sexy as my full carbon 57T
Just "found" another DA cassette that's been on the kitchen windowsill for months now. I think it must've been off old race wheels, so at least I've got that spare.
