Front Derailleur Clamp Torgue Carbon frame
I'm doing my first carbon build with a 2017 Raleigh Clubman carbon frameset. I searched around and couldn't find an answer for certain. I assume the clamp torque is the same regardless of frame material, but wanted to confirm. 5-7NM is fine on a carbon frame? I would hope they would build the frames to handle the recommended specs for the derailleur, but just wanted to check.

that's about the same torque as used on a seat post clamp.
seems appropriate... if you're worried, just use a lower spec. of 4nm, then add a bit if the der. slips down during use.

May even want to put a smidge of carbon assembly paste on the contact surfaces of said clamp before installation.

most new CF bikes use a mount plate affixed to the frame now, right? even my aging Fuji CF bike uses one.
i don't see many new CF bikes in this shop.. mostly older MTBs and BMX bikes.
just tore down a rear wheel yesterday that had Every Nipple rounded out, except two, and one spoke finally broke from the intense overloading... the rim went outward about 3/8" right where that spoke failed... "can you straighten this rim out?" i sold him a new/used wheel... it all started with a tiny out-of-true, and some bad advice from his "buddy".....
