Thanks for all the useful information.

I have never had a tri bike and cannot afford to buy one new. I have seen a second hand 2017 Speedmax CF 8.0 (I actually suspect is a 2018 Speedmax CF 7.0 2018 Canyon Speedmax CF 7.0 – Specs, Comparisons, Reviews – 99 Spokes) in my local area (very remote and 2nd hand tri bikes don't come up very often). It's a size small however using Canyons size estimator I should be slightly into the medium bracket.

Since i have not had a bike fit and do not own a tri bike do you think i could make the small work for me?

I'm: 176cm
Inseam: 84cm
Weight: 68kg

Hi Ian!


I just, for the first time ever, measured my existing bike! lol

Based on these measurements, would you recommend Speedmax CFR S or M?

Again height is 5’6” and inseam 31”

Thank you

Ian, hope you're still doing the fit assistance thing... According to the Canyon fit tool, I'm a medium... But it looks like I'm right on the border of medium/large. With availability being very limited, I'm wondering if I would fit either a medium or large with "room to move" as you mentioned in a previous response.

My retul numbers are below, but I should mention these numbers were femerateion a bike I already owned. Of note, we had the reach pretty much maxed out. I guess I could've gotten a longer stem, but thinking back that was actually never mentioned by my fitter. So, when I say room to move I am mainly concerned about being able to length out the torso a bit.

I'd appreciate any guidance so I can jump on the appropriate size when they become available in the States.

Seat hight: 796mm (BB to center of seat profile)
Armpad stack: 679mm (BB vertical to top of armpad)
Armpad reach: 500mm (tip of saddle to back of armpad)

Can I double check what you mean by inseam? I have provided the figure the measurement from the canyon website that measures book between legs to floor.

The reason I ask as I have never been described as long legged. I suspect we may be talking different measurement.

Thanks again

I guess that would be good to know. I'm looking at either at CFR or SLX. I sent you a DM with my full fit sheet. Thanks!

Another edit...

I looked more closely at my fit sheet and I gave you tip of saddle to back if armpad for reach. I also looked at the CFR geometry specs and it lists a range for reach (BB to back of armpad). That number for me is 475mm. I think I could go a bit longer for some added comfort.

Geometry specs are not my wheelhouse, but I think that puts me in a large as the medium range appears to be 408-463mm. (Unless there's something that can be done with stems.)

My gut is telling me L, but the fit recommender for canyon says M so it has me nervous about that.

I gues you wouldn't ship the 90mm v21 stem to the UK?

Hi Ian,

Chasing some advice on sizing for the Speedmax CF SLX. Please see below:

Height: 177cm
Inseam: 84cm
Wingspan: 186.5cm
I have long legs short torso with long arms

I have had 2 x Pre bike fits and both said to go the Medium Frame but then Canyon said I would be better suited to a small and noted going the medium with the factoring of more reach would still have me on the smaller side of the medium where the small gives you a heap more room to also play around with the adjustment too ?

What would your thoughts be ?
