2014 Cervelo R3 Ultegra sizing

blue-bird

I'm looking to get one of these but my current bike is pretty much bang in the middle of a 56 and 58 (A Lemond Versaille 57). I've sat on both bikes and could make either fit. I'm 6'1.

My worry with the 58 is that the head tube is taller than my current bike, and I don't run any spacers on my current bike. On the 56 I worry I'll have too much seat post out, I can add a couple of spacers to raise the bars so that isn't an issue.

Has anyone got a 56 that could tell me the measurements from

a) the centre of the cranks to where centre of where the top tube joins it, and
b) the centre of the cranks to the top of the seat tube

Thanks

Go with the 56 unless you have arms like an orang-utan. The Cervelo's arent particularly agressive in their geometry. I am just over 6 foot and size up almost perfectly (as per Retul) on a 56 Cervelo. you will have a lot more scope to adjust the fit on a smaller frame than the larger one.

Thanks Calpol, that's what I'm thinking. It could be that the 58 is fine, but if I want to be lower the only option I have is a -17° stem and then I'm out of options.

I'd say I'm a fairly average 6'1, not especially long arms or legs. What's you cycling inside leg?

Just as a reference, I'm 6'4 and I've got a 58 with no spacers, so I'd say the 56 would be a better bet.

Hi Jack, do you like your bikes compact?

I'm 182/6' with an older 56cm R3SL (16cm HT) and I need 1cm of spacers on top of the conical cap so if I had the new 58 (20cm HT), I'd need to ditch the conical cap for a flat cap and maybe get a negative stem. No go.

The front end might feel stiffer with the 58, depends how aggressively you ride.

If you go downhill alot and are not confident descending (I'm getting more wary with age) then a bigger frame feels stabler due to the longer WB and the longer FC means it's slightly less twichy than the next size down. Pretty small differences.
