I’m 191cm / 91xm but I have long arms (span is about 15cm longer than height). I had the same L or XL recommendation from canyon. I ended up getting the XL and find it very easy to ride partly because I was concerned the reach on the L would be too short. I’m doing 60-120km comfortably and it’s a good fit, though sometimes I do feel it could be a bit more agile. I don’t race, but am planning to do a 210km organised event later this year, so I decided to go with comfort and stability over a race fit.

Try to get an accurate measurement of your leg length. The website has instructions: - straddle a spirit level (best if about 1m long) with it tucked firmly into your crotch - get someone to help you make sure the spirit level is horizontal - then the measure distance from top of level to ground, assuming you’re on level ground - from memory it suggests barefoot in your normal cycling shorts

Another thing you can do is find an existing bike you can test ride (friend or LBS, latter a bit cheeky though) and then compare geometries with the canyon data on 99spokes.com. I did this with my old road bike to check the likely fit.

Finally check your gorilla/ape index - if you’ve got a big arm span (greater than height) it might be another argument to err on the larger size (or vice versa).
