TE - is that the same cheap Chinese carbon that was 4 minutes faster than you on the bike at Outlaw last year???
FWIW - and I don't pretend to be an expert at all, I've got an Exocet 2 and the day I feel the bike is the limiting factor I'll be a very happy man. I would say the own brand aerobar / extension set up isn't the best and I've replaced those as well as added a quarq and a Cobb saddle, but I would have had those last two on any bike I bought. Otherwise it's as PX intended.
I've always found PX customer service pretty good, better than my LBS anyway.... Like most places it seems to depend who you talk to. For a largely web based company their email based comms maybe aren't the best
Doesn't matter at all - that's a question of engine. But there's no prizes in T2...
