Sorry if this has been done.

Mate wants a Aeroad CF SLX 7.0 DI2 but needs to try one out for size.
Do Canyon have a place in London where you can do this?
If not, how would you progress an interest in it if it was you?

Thanks

Nowhere to try one. Either find somebody with the model/size you want to try or trust their sizing/fitting instructions on the site.

My Nerve and my wife’s Endurace both fit perfectly after following their instructions. Not sure whether their road bike fitting instructions are fuller than their mtb ones or it’s just a recent development but we took more measurements for my wife’s bike – shoulder width, arm length, inseam etc

Bugger.
In that case, does anyone have a Canyon roadie within a 50 mile radius of Leamington he could sling a leg over, and be happy to do it? Totally legit, even if it does sound a bit dodgy 😳
Obviously he needs to work out what size he thinks he needs first!

Why wouldn’t he take the measurements as per the website and trust that they get it right?

Given that most people do this and you don’t hear horror stories it seems sensible.

Compare dimensions to his current road bike if he has one. Or Try some bikes from different brands that are roughly the same size as the Canyon.
