Hi Ian -- Does it look like I need the longer stem for my Speedmax SLX (size M, standard 65mm? stem)? Should I actually have ordered a size Large? See photo.
I'm on a size Medium with aerobars fully extended (i.e., they are slightly recessed into the armpad clamps, actually). Some more details on my fit numbers are:
Saddle height: 767, setback -19mm
Arm pad stack: 639
Arm pad reach: 460
Crank length: 165 (I switch the crank to 165 from the stock 175)
I feel like I need to get longer, but at the same time, I feel like my weight is already WAY out over the front wheel, which has me wondering if I should have gone with a Larger, though standover height would be a concern (860 mm inseam). As you can see I am using the Canyon angle brackets, and I also have adapters to make the aerobars wider.
Let me start with this.... I read your "frustration" post and I'm so sorry you're dealing with this drama. Bike fitting is a combo of art, science, and math and it takes time to get learn how to fit and then it demands that a fitter keep up with all the industry changes: terminology, saddles, an understanding of crank length, bike design, etc. etc. etc. And that is just for road. And's road fitting is f*cking easy in my opinion - tri is a magnitude harder. There are many of us who are good/great at fitting the triathlon position, some have been recommended, some have already weighed in on your post, we want to help you solve.
Let's start with this note of calming comfort - I'm 99% certain you are on the right sized bike. That bike is sexy as hell and you're close enough to the right position that I think we can get there rather quickly.
Can you confirm something for me...your bike, it's a 2018 Canyon Speedmax SLX right? I'm pretty certain of that based on the graphics. The thing that's confusing me is that you're on a medium and your Pad Reach is 460. The shortest the 2018 SLX Medium goes to is 462. Wait, are you measuring your Pad Reach to the rear of the pad??? The "Canyon Way" is to the center of the pad so your current pad reach is really 510ish? The pad's are roughly 100mm across, so the rear to mid point is ~50mm so if we add 50mm to 460 we get 510. I want to confirm those bits first - year & where pad x is being measured to to get 460.
Also, your "using adapters to make aerobars wider" - do you mean the TSP (Team Switch Plate) that are designed to move the pads beyond the capabilities of the stock arm pad mounts (and by "move beyond" I mean farther forward or farther back of the stock mounts). If you're unsure - pull the velcro pad off both arm cups - then unbolt one of the cups and leave the other bolted in place - then post a pic here on this thread taken looking straight down at the bars.
This is super important to clarify because you absolutely need a longer cockpit but the expectation here is that the medium can move out to a Pad X Center of 516 with the short stem so first I need to figure out where you are before I make a suggesting on how we're going to get longer.
I'm at home a ton this week and I'll be looking for your reply. Stay with me on this, let's get it solved.
Thanks Ian -- I really appreciate your response and willingness to help me get situated on my Speedmax. My main goal is to make sure it's the right frame and that I have the right cockpit accessories for when I eventually find time to visit Jim M, but it might be a while before I can see him so getting better situated beforehand would be great.
To answer your questions: yes, I'm on a 2018 Speedmax SLX. The only component I've changed is the crank to 165mm, to open up my hips and help me get lower. For the front-end, I am using both the "Team Switch Plate" to extend my reach, the "Switchblade" spacer kit to widen the arm pads, and the "Angled Spacer Kit." Here is how I have my front-end spacers set up, from top to bottom. Big (1cm?) spacer, switchblades turned out to widen arm pads, another large spacer, the Angled spacer, then the Team Switch Plates (set up so pads are max distance away from me). My aerobars are fully extended (such that they are about 1cm recessed into the aerobar clamp). So as you can see, I'm really going to the extreme max (probably beyond recommended spec?) to get longer and wider.
Sounds like you think I need a longer stem? I think Canyon offers an 85mm stem, tough not sure how that would impact how the bento box and integrated hydration sit. I do also wonder if my saddle is too far forward and that's what's making me cramped and impacting weight distribution? My saddle is pretty much fully pushed forward. I generally find myself creeping to the nose of the saddle though and feel less powerful when I set further back on it.
In terms of your questions on some of my stack/reach numbers, I will just go ahead and email you my full Retul fit report as well as body measurements for a recently made custom road bike. I suspect that will make things clearest.
Thanks again. I'm very grateful you and Canyon are doing this. This thread will help so many people.
