bike fit arrrggghhh!!!

The stats said that i should be on a 54 frame, but riding i found out that a 52 frame is better for me and i am 5'7 with a inside leg of 30cm.

Try before you buy

Riding it is undoubtedly your best bet.

But just sitting on different bikes a reasonable space of time apart it's very difficult I think to carry the impression of a bike's fit in your head from one to the next. So unless they're in the same shop at the same time and properly adjusted for you (not just setting the seat height) it can be a bit of a lottery.

I'd suggest looking at the reach and stack figures and comparing those to your current bike or one you know the fit of to give you a point of reference e.g. I could do with another 25mm or so of stack on my current bike but the reach is good so Canyon's Ultimate CF SLX is just the job in a 53 - apart from the small matter of the money

You still have to be careful though - bikes with similar reach but different horizontal top tube lengths will need the fore/aft position of the saddle adjusting which may get you into in-line seat post territory on some configurations.

Oh, and whether a manufacturer calls their 52.5cm htt frame a 52, a 53 or a 50 is completely random and best ignored I think.

I know 3 guys with canyons and for bike sizing were bang on using their calculator.

The two bikes you show have slightly different purposes.
The Focus is an out and out race bike, the Bianchi is a little more comfort orientated (only a bit though, by no means is it a sit up and beg bike).

There's a good guide on Cyclingtips.com.au on understanding geo sheets, might be worth a read which can help you get your head around what things mean and the impact of longer/shorter/steeper etc.

You also need to look at the CR1 you have, is there anything you really like or dislike, they could be pointers of things to have or avoid on the next one.

Also a bike fit (I'm assuming you mean something like Retul or a BG one?) is quite useless till you have a bike in mind, a proper bike fit just gives you a load of numbers to set up the contact points, you could apply those numbers across a range of sizes of the same/different bikes and get the same result of fit but the bikes handle in a different way.

You need to maybe have a think what you want out of the bike.

All manufacturers are marginally different. There is no substitute for actually sitting on the bike.

Canyon have an excellent bike size configurator on their website but of course that is for their bikes.

If you are going for a "dream" bike, it should be custom build to suit you, from a British frame builder and nothing off the self that anyone can own
