54cm frame for 6'3?

Hi guys

So i have been using my bike for nearly a year - bought second hand as I was a newbie.

It was until now I checked the frame to see the size was 21.3cm - 54cm. It was weird because it was advertized as a large frame?

it probably is too small. I am 2 inches shorter and I use frame with an effective top tube of 57 to 59cm. one bike has a 55cm horizontal top tube but it has 140mm stem and seat post with set back. I normally use in line posts. seat tube angle is fairly steep on this frame.

So unless the top is long or you have an insane stem or maybe very short arms the frame will most probably be too small. Size a bike by the top tube rather than the seat tube. Seat posts go up and down lengthening the seat tube top tubes cannot change length.

See your other thread.

FFS, you really have fitted a front Zipp to that!

It is a rather big frame, but its sloping, so seat tube measurements are irrelevant

Seat post looks higher than typical but your saddle seems quite far forward. I'd take a guess that it's not a 'typical' 54. If you haven't had a bike fit etc then maybe your seat would be better placed a little further back but you may need to lower saddle a little. Why do you have the saddle sloping so much downward? It may feel better further back and a little more level. Hard to be sure from a photo though!

All eyeballing is irrelevant without seeing the rider, but the frame size looks plausible - on a race bike with a small frame, anyway. In such a setup I'd expect to see a slightly longer stem, and definitely a layback seatpost. Even with that said, though, that saddle setup is ludicrous - level it and push it back.

If you want some slightly more useful guidance, put your bike on a turbo and record some side on video.
