Giant Trinity Alliance
 

This is a fit question for those that have the trinity alliance or are familiar with the sizing of it. I am 5 ft 11 and currently ride the tcr adv. in a Med/Large. It is the perfect size for me. The TT length is 57 while the trinity TT is 54. The Trinity Alliance does not come in a med/large; The TT is a 54 on a Med and 56.5 on a large. My inclination is to go with the medum as it is a TT bike but a 54 tt seems to short. Is anyone riding a med or large trinity alliance and can give me a general idea on their height? What I am looking for is to see (generally) if a med is to small or a large too big. Thanks

You will usually ride 2cm shorter top tube or so on a TT bike. I would get a Medium Trinity

awesome thanks, thats what I needed to hear

The trinity alliance is a TT bike right? They suppose to be shorter than road bikes.
