Re: Curtlo fillet-brazed road bike frame + headset & seatpos
Yeah that seems odd, how you measuring it?
Actual TT should be centre of headtube to centre of seat tube, along the tube.
Effective TT should be a horizontal measurement from centre of headtube to where the horizontal line intersects the seatpost. Bit hard to measure exact sometime, especially just frame.
p.s, thanks for measuring but looks to small for me anyway, cheers.
