In the past I’ve used a seatpost with 7x10 clamps to secure a saddle with 7x9 rails. It cut the rails up a bit with the proper torque so I ended up having to get a new seatpost that had 7x9 clamps. Well I just ordered a Madone Friday that should be at my LBS in a day or two which I have 7x10 clamps …

Did you check with Trek (Bontrager?) since the seatpost is exclusive they might have an adapter. You have a Fizik carbon rail saddle? actually i googled it and it appears you need this - Bontrager Rotary Head Seatpost Saddle Clamp Ears shocked that I got here before @mcneese.chad Mike

Cobb (Speed and Comfort) Carbon One. Per Trek that’s not compatible with the Madone seat mast nor do they make one in house. That’s for the Emonda style seat mast.

Ahhh I see - I did some additional googlefu and am stumped as well. Do they sell a 7 x 10 metal rail version of your saddle? Not ideal but better than clamping down on a carbon saddle and hoping for the best. also Mitch form Trek is on here as well as Slowtwitch - might drop him a line

Guessing you’re talking about the San Remo or the new Pro SR. Could’ve sworn I test rode the San Remo then got the 151 instead before also buying the Carbon One. Still have the 151, just prefer the carbon top (no padding). 151 is actually the saddle with the marked up rails I mentioned. At any rate,…

[Mitch@Trek] on Slowtwitch and there is Trek link " [Hey SlowTwitch - Trek Community Manager Here!" in the main forum where he responds almost daily @MitchatTrek on here, but I don’t see him as often
