I was hoping someone could ensure my logic is sane before I splash 2k on a Canyon.
Currently running a medium planet x SL [url= http://www.planetx.co.uk/i/q/FRPXPCRFF/planet-x-pro-carbon-road-frameset ]Pro Carbon[/url] with a HA of 72.5, SA of 73.3, reach of 385 and an effective top tube of 547. I'm running this with a layback post and 90mm stem.
New bike in small [url= http://www.canyon.com/_en/roadbikes/bike.html?b=3241#tab-reiter2 ]canyon Ultimate CF[/url] has same Head and seat tube angle, but has a effective tt of 537, and reach of 375
With the same layback post and by getting a 100m stem will the fit be pretty much exactly the same, or am I not taking something into consideration?
other option is the medium, but I'd rather size down than up and 56 seems like a big frame.
The "56" doesn't seem to have any relevance to the sizing. The medium is only 2mm longer than your PX . If your buyi g the full bike, think about the crank length too - medium is 172.5 vs 170 for the small.
How tall are you?
What is the stack height?
Are you using the same bars?
Some spec on that Canyon!!!
The wheels & groupset alone are about £2k worth..... 😯
Slight hijack - can someone point me in the direction of the original thread (I've searched but cant find). After some DIY bike fit guidance 😀
Despite the often repeated idea that road bike fitting is amazingly important, you don't have to exactly replicate your current position; you are adaptable and can cope with some changes.
Your position can and will change over time anyway.
