MDCC, here's a question, what sort of fixed GI should I go for on a 10 mile flat TT? I was thinking around 80-85, but I have zero experience of riding fast fixed.
I don't think there's any 'correct' answer to this question.
Ray Booty did the first sub four hour 100 on 84", whereas I, a greatly inferior rider, need 90" to go slower than that for 25 miles, and I know from experience that if I used 84, I'd go even slower.

Experiment - see what suits you best.
