Great to hear from some other Giant riders! I've had some difficulty finding any shops who do the giant frames in XS, have a feeling the xs would be fairly ideal though. Unfortunately, the tcr composite doesn't come in that size.
Jodz, it's quite reassuring to hear you get on OK with your TCR. What sort of build are you, short legs, long torso or vice versa?

I'm going on a ride tomorrow, will try to post some pics (this would be before any adjustments to bar and stem as haven't taken the bike to the shop yet).

Keep your ideas coming!
