Looking for assistance from anyone who has experience with Look bikes, specifically a Look 464. I've been told by different folks that the sizing is a little weird with Looks and I want to make sure I get the right size.

I'm 5'8" with a 30" inseam.. should I get a medium?

You don't need someone who's got experience with Look bikes; you need a geometry chart.

The medium, with a 56.5cm effective top tube, is going to swallow you up.

First things first: Do you currently have any bikes that fit you well? If so, what are they and what's the top tube length?

I currently have a 51cm cervelo p3. It's comfortable, but I feel it's a little on the small side and should be riding something bigger.

I'll have to do a little homework because I'm not familiar with how to read geo charts.

Thanks for the post!

It sounds like maybe you want a small then (I thought extra small before--it's not actually that small), but it's hard to make a direct comparison because of the Cervelo's unusual geo/riding style. It's best to go to a physical store for a proper fit if possible.

Folks also recommend this fit calculator, but I find that most people take their own measurements so badly that the calculator results end up not being very reliable.
