hey guys im looking to get a Mercier TT stripper but i want to make sure i get the right size before i bite the bullet. My height is 5-10 and my inseam is 33.5 inches which is 85cm x .67 (To get to C-T) i get 56.95 which is between 56 and 58 and when you convert it to C-C it is between a 53cm or a 55cm bike. Im torn between the two any help will be appreciated. Thanks!
