Thanks for this great thread.
I already bought my first Tri-bike a Speedmax CF 7.0 in L after test riding and discussion with Canyon. I was exactly between M and L. The reason for the L version was that my knee was very near to the elbow on the M size bike. Teh position was fine for me. Now after several days of testing and searching the right position on the new bike, I got the feeling that the bike is too large for me. I am planning a bike fitting, but would prefer to take my new bike with me to find the perfect position.
Probably you can give me a hint, if M or L is the better choice for me. Here are my measurements I received at Canyon.
If it helps, as roadbike I have a Ultimate AL in size M and it fits perfect.
Height: 182,5 cm
Inseam: 88,5 cm
Torso: 64 cm
Shoulder width: 45 cm
Arm Length: 61 cm
Saddle height: 78,5 cm
Thanks for your help, I really apreciate!!
