Hey guys,
I just bought a Canyon Endurace CF SLX 2017 and I’m having some issues with the saddle setup. The bike has the Canyon S15 VCLS 2.0 CF seatpost.
The saddle wobbles/tilts front to back. For example, if I put weight forward, the saddle tilts nose-down slightly, and if I push back it moves the other way. It feels like there’s play somewhere in the clamp/rail interface even when tightened properly.
In the picture I use a Fizik Aliante R3 saddle, which from what I understand should be original or at least compatible. But the rails don’t really seem to fit the clamp properly. There’s quite a lot of space above the rails and also on the sides, almost like the clamp shape doesn’t match the rails at all.
What’s confusing me even more is that I’ve actually tried multiple saddles now — both round and oval rail saddles (although I’m not 100% sure of the exact rail dimensions on all of them) — and none of them seem to fit properly either. They all seem to have some play or weird spacing in the clamp.
Am I crazy here or does this sound like the wrong saddle/rail type for the S15 VCLS clamp? Has anyone else had this issue with the S15 seatpost on an Endurace?
What should I check first? Wrong rail size? Missing adapters? Worn clamp pieces?
Thanks!

It appears you are looking for bike fitting help. Please make sure you post as screenshot of the Canyon size chart for your bike, with your point in it. See [this example](https://imgur.com/a/ALUfXyy)

You need the round rail mount not the oval ones
Your saddle is for carbon rails with 7×9 dimension. There is a different clamp available from Canyon for round rails.
You need to buy the rail adapter from canyon. Your bike is set up for oval but your saddle has round rails. I had the same issue when I switched to a fizik saddle
