Hi Ian -
Wondering if you're still able to help with a Speedmax fit, or if this thread is long expired for help. I've been riding an entry level road bike that I came with a complimentary fit in the store, so I am not as familiar with all of the measurements you'd need - if you could link me to a thread that may help me obtain these, that would also be of great help.
I am 187 cm tall and have an inseam of 82 cm.
rookiefro,
Based on your slightly longer torso morpholgy I'd say your Pad Y is in the neighborhood of 655mm and your Pad X is roughly 505mm. These numbers tell us where the arm pads sit in relation to the bottom bracket, and they are what we use to shop for the proper size tri bike.
Canyon makes... essentially... two verisons of the Speedmax tri bike..
1) is the CF and that bike sort of a "mortal bike" meaning it has a pretty normal stem on it, a stem that we could change to different size in about 90sec.
2) is the SLX or CRF (same in terms of fit and geometry) and that bike only has two "stems", a long and a short.. and it's not really a stem it's a base bar, molded, carbon thing... and it's got brake lines and sometimes more running through it and it takes a day to change out.
If you wanted a CF... the medium. You'd be right in the middle in terms of pads up and down (Pad Y) and you'll probably need to push the pads out almost the max to get the Pad X right.
If you wanted the SLX/CRF... you'd be a large with the long stem, mid spacer, medium extension.
Get back me if you have any more questions and I'll respond promptly.

Ian! Thank you so much for taking the time to reply - I am looking at the Canyon Speedmax CF 7 Disc eTap when it's available later this month. The Canyon fit tool says I would be a large in that frame based on my measurements - clearly only two measurements are less precise than what you provided. Would there be any additional info/measurements I could provide to ensure that a Medium is the proper size for me?
rookiefro,
First, to answer you question directly - if you gave me your seat height and assurance that you haven't had some major issue.. like a car crash that resulted in 5 fused vertebrae.. then I could go perhaps a millimeter further in confidence of my prescription.
It's VERY common that one person can fit on 2 and even 3 sizes of the same make/model bike. I do think you could fit on a Large Speedmax CF, but I think it might leave you up higher in your arm/shoulder/head position than you'd like - even when slammed ("slammed" is roadie slang for pull-out-all-the-spacers-and-pedestals-and-get-as-low-as-possible). I want you to have the freedom to go lower if you can.
Now, here's the problem... bike fitting is very real. It's part art, part science and in this scenario (you investing in a Speedmax CF 7 and spending hundreds of hours a year over perhaps 10 years in comfort, feeling powerful, and being fast) it's so, so, so worth the $249 (in my fit studio) or even $399 (in some other fit studio) to have a prescriptive fit done. A pre-fit is where you go to an educated, experienced, fitter with a dynamic fit bike (gotta be all three of those, you can't skimp on even one) and they put you through a process that results in your Pad Y and Pad X so we know exactly what size bike you need and what the front end configuration will be... AND... you have all of your fit coordinates (seat height, set back, pad elevation, pad width, aerobar tilt, and so much more) so that the fit for your new bike - the bike you haven't even purchased yet - is finished.
You might be thinking... "gosh, I wouldn't be having this problem if I walked into a bike shop to buy a bike. They'd tell me what size I needed". Let me speak to that for a sec.... There are very few "fit first" bike shops. They are great and they are EXTREMELY rare. The vast majority of sales folk will have a look at ya as you walk in the door, estimate your height at about 6'1" and when you say "i'm here to buy a tri bike" they'll take that height estimate, apply it to what they know about road bikes and say.. "I've got a 58cm right over here". That experience is far worse than what you and I are doing here now.
That complete art/science process of a pre-fit - can't be done on the phone, over a website, or even with me here on this forum. So.. the question is.. are you gonna take my free and savant-like advice and run with it - many have, it works. Or are you gonna tell me what city you live in so that I can recommed a fitter (if I know one in that area) whom you can see so that you do this perfectly. Those are choices: free-pretty darn accurate.... or.... $$$- perfect.
Let me know. I want to help either way.
Ian
