Go and sit on one. Pointless trying to size a road bike over the internet.

A 60 with a long stem would probably be reet though!

I'm a smidge over 6'2, 33" inside leg, and on a 58cm CAAD10. Had a proper fit after a few months of ownership and I now have a 130cm stem and the saddle right back, and more stem spacers than perhaps are aesthetically acceptable, and it fits really well 🙂 So with hindsight I maybe should have sized up, although the guy who did my fit said 'nah, all the pros ride small frames', which made me feel a little a little better. Sounds like proportionally you're in a similar place with 60 / 63 (not taking in to account torso size, flexibility etc). One thing I will say is that the 63 will look like a gate - do you want to ride a gate?

But yes, the short answer is try one out.

Lovely bikes btw.

I think a 60 should be the right size , Cannondales idea of a 60 is actually bigger than most manufacturers .

6'2", 34"inside leg - 58cm CAAD10 - fits fine (after adding a couple of spacers and tweaking bar position). Brilliant, comfy, fast bike.

*Edit* The 60cm should be fine for you.

I am 6ft2" and have used a 58cm,Felt really good,I would say a 60cm should be fine,But without seeing you sat on one its difficult.

Thanks guys. Sounds like 60 it is.

Other question is supersix standard mod or caad 10? At moment thinking caad. Not sure why but seems to make sense!

Most people (including me) rave about the CAAD10. I have no experience with the supersix but I would not swap my bike for one.

Also no experience of supersix (or other carbon frames). I'd go for whichever has best wheels / groupset, as thats where you're likely to see most noticeable difference between these 2 frames. If same apart from frames, I'd go supersix.

Caad 10 is Aluminium,Super 6 is Carbon
