Hi, I am looking for older 2018 canyon speedmax cf slx 9.0 used bike and there is one in size M available. The previous bikefit is attached.
Juha, The fit coordinates in the attached look great and are very useful for your fit coordinates but don't help me in the prescription. I need the Pad Y and Pad X from your bike.
If you can, please take the directions from this short video and get back to me. If that's not possible... let me know your overall height.
https://www.youtube.com/...pZa8UIIwrYE&t=3s Seat high 73cm
Pad x 40cm
Pad y 67cm
The pad is 7cm tall. I have changed stem from this bike from 90 to 110. Even then my elbows are at the edge of pad , so not the center of arm isnt on the when I am riding. My hight is 175cm and inseam 82cm.
Juha,
There's a lot of good info in here, thank you for including it all.
The size Medium of the 2018 rim brake Canyon Speedmax SLX will not come up high enough to meet your Pad Y. That bike was VERY long and low. The highest the Pad Y gets on that bike in a Medium is 650mm. You'd need a size Large to get to the 670mm Pad Y and you'd need that Large with 40mm of pedestal under the pads to arrive at 670. In terms of the length none of those bikes (small, m, or large will go as short as 400mm in Pad X).
You have long legs for your height and that means that your Pad Y will be a hair higher and Pad X will be a hair shorter than a guy your same height but one who has shorter legs and a longer torso. If you had ONLY told me your height and inseam I would have guessed your Pad Y to be ~630 and your Pad X to be roughly 450 (and, that can fit on a Medium). This makes me suspicious of your position - perhaps there's something about the equipment or position that keeps you from riding longer and lower. That quesitons I'd ask are these...
1) Were these numbers pulled off of a road bike with clip on aerobars?
2) If it is a triathlon bike with triathlon geometry - what saddle are you using and where are you sitting on that seat?
3) If it's a tri bike - how long are the cranks?
Let me know, let's keep investigating this - a Medium, 2018/rim brake Speedmax SLX might still work.

1) That is 2015 Felt B16, size 51 (tribike).
2) The saddle is Felt OEM. I have tried other ones but that is the best one. I think I sit more on the back of the seat ( or in the middle). It is hard to stay in the front end.
3) Cranks are 172,5mm now.
Juha,
This explains a lot - that saddle is basically a road saddle and you're sitting towards the back of it for comfort. This puts your hips in a place where you are basically riding a "shallow" seat angle of ~76 degrees. When your hips are back that far then your arm pads have to be up high (Pad Y of 670ish) and back (Pad X of 405ish). When we move into a more comfortable, more powerful, more aerodynamic position... we move the hips forward over the bottom bracket and then the pads move forward and down, forward and down, forward and down - you wind up closer to Pad Y of 630ish and Pad X of 450ish. Comfort is maintained. Power can often increase, AND we get out of the wind a bit more.
That's the natural progression we've been on in the triathlon position for 20 years. That's where we are now. That's how a Canyon Speedmax is designed to work with the human body. HOWEVER that doesn't mean the rim brake Speedmax SLX will work for you, it only suggests that your optimal fit is far closer to 630/450 than it is to 670/405.
The rim brake SLX is (was) a pretty long and low bike and the new disc brake Speedmax bikes are shorter and a bit higher now.
Here are my thoughts based on the info I have now..
1) the best is that we find a great fitter (education, experience, dynamic fit bike) that you can get to so we can really solve/finish this process for you. There will be expense in this process (a day to get to them, maybe $300 for the fit itself, gas, etc) but in the end it's worth it because you'll know EVERYTHING after the fit: the best saddle for you, all your coordinates, and your real Pad Y/Pad X. Then when you buy your next bike you'll know it's right and you'll be comfy and fast on that bike for a decade.
2) you start to play with the position on your current bike by forcing that saddle forward to the max (assuming you'll still sit on the back of it) and progressing the front end out 'n down, out 'n down, out 'n down until you find a spot that feels GREAT. Then we take that new Pad Y and Pad X and see if that rim brake, medium SLX will work.
I can help #1 if you tell me the area in which you live. If I have a fitter there I'll connect you. #2 is a bummer because it takes time to make those changes when you could use that time to actually be riding - but maybe you're game.
