I currently ride a specialized tarmac sl2 and i have to admit it is a lovely bike. I am thinking about getting a tt bike and was wondering whether anybody has any suggestions for a sub £400 tt frameset. If so would an aero bike with a frame this cheap be better than my road race bike with drops at time triials. Thanks in advance.
