Also every manufacturer will measure bikes differently Fishy. (Tubes centre to centre or from the edge etc)
I tend to look at top tube (6ft1) and use 57 top tube.
Like Dave says, find a local bike shop (LBS) and try it.
Roadbikes are like shoes-need to try and everyone is different.
Also you could get a local Shop to "bike fit" you and then order a bike online based on the measurements that would suit you.
yeah, that's what i find too, only i'm between a 58 and a 60. Nobody makes a 59![1](https://cdn.road.cc/sites/all/modules/contrib/smiley/packs/smilies/1.gif)
Hi Dave,
Brill, thanks for injecting a little bit of science into that one, I'll be trying a 56 Allez tomorrow, and I would imagine my perfect bike is either a 56 or a 58 (of any brand) the deciding factor being the length of the top tube.
your inseam is 49% of your height which is high but not abnormal, about the same as mine. What I find is that I just tend to run a lot of seatpost, whatever I'm riding. Also, bikes that *look* right when i set them up (ie the seat isn't high) are often a bit long.
There's no substitute for trying a few bikes and seeing what you like the feel of. Go down to your LBS, take a tape measure, try a few bikes and measure the ones you think fit you the best. The next step is to get a proper bike fitting, it'll cost you some money but it's a useful exercise.
