I am in the process of purchasing a new speedmax, I have been eying the CF8 for a while now. Like others I am on the fence around sizing, based on the the fit tool Canyon provides my recommended size is a Medium. But a centimetre or so more and the tool puts me up a size to Large.
Height - 184 cm
Inseam - 89 cm
Saddle Height - 78.5 cm (road bike)
Unfortunately I moved on my past Tri Bike (med, Shiv) before taking any measure of cockpit geometry to ensure that the medium is going to work so I am a little nervous hitting the go button. Bike fitters with access to fit bikes are few and far between so validation that the medium is the right starting point for me would be appreciated, apologies I can't give you more to go on
