It may not be a massive difference, but it might just be enough of a difference between holding onto, and losing the wheel in front. There are a few sections on Box that allows for drafting, so holding on to wheels will have an advantage. I'm a lighter rider (compared to most C riders) so I'm hoping I can get away with a more aero set-up with lighter wheels, rather than say going full Tarmac lightweight. Heavier riders tonight may have a better chance with a lightweight bike/wheels set up just to give them that slight advantage on the 12 mins of Box Hill climbing
May be absolute bollox, but that's my personal view
Agree. Zwiftinsider has run a tonne of tests and will tell you exactly how much a wheelset change will help on a climb or on the flat but that's based in a solo effort. In reality being able to hold onto a group may only need 1% more effort on a hill but by then drafting your time will be much faster, and psychologically knowing that you have the fastest bike helps me (until you get overtaken by someone on a mountain bike)
