Road Bike Frames, Wheels & Components / Re: XM Carbon Speed - "Gran Tourismo" Frameset
« on: May 10, 2026, 03:07:31 AM »I've had the frame for a while and i was able to test it in different scenarios (flat rides, punchy walls and long climbs, both long and short days in the saddle), i can say that the frame is very comfortable with a reasonable tubeless setup, absorbs road chatter without sacrificing responsivity. So far i had PBs on a lot of segments around me so it's definitely faster than my old MY21 rim TCR
i only have two issues with it:
- the saddle keeps slipping back during the ride (steel rails). Peter suggests 6NM for the saddle clamp bolt but it's not sufficient. has anybody had this problem?
- when out of the saddle and moving the front wheel a lot side to side the front brake rubs a bit. This could be flex in the for blades or maybe a compatibility issue (I'm running wheeltop calipers with stock pads and a shimano rotor in the front)
Picture for color reference, pretty pleased with how it turned out!
the saddle slippage seems to be fixed after changing saddles, maybe the previous one had dented rails from over-torquing on another bike, 6NM is enough on my end.
