Think the only standard stuff is cranks(bb, ffw) rear brake and splocket.
want a new frame but dont have the cash at the mo and want cranks for my birthday.
Its true though, all those stems you listed, have you actually tried them and foud them the best, or just got them from Tarty?
But Like Duncy H, get a Trialtech race, mine is awesome!
Tarty and Select stock HS33's because most trials riders use them. The reason LBS's dont stock them is because most of them dont do trials stuff. I've only seen a few bikes that are nott trials with HS33's from companies that my LBS stocks but they dont sell them individually.
