I'm changing the alu seatpost on my Bianchi Via Nirone to a carbon FSA one - anyone any idea what tourque setting to use for the bolt? The FSA guide os to check with the frame info, but the Bianchi manual and website doesn't say what it shoule be.
6.8 do not go over this unless you know its ok to do so.
i did and it cracked and i didnt know this and over time it got bigger and bigger and stil not knowing it was there i go out on a ride and boom it let go. phone up a shop that sales bianchi and ask them what the tq setting is.
slow down. Literally. Start at 4nm and if it slips try 5.5nm. Any more and you may deform the pin! A tip to stop carbon slipping is to dust it with talcum.
Hope I'm not too late posting and this helps?
Cheers all - I'll give it a go tomorrow. I have had problems with the alu one slipping, despite tightening much tighter than I would dare with a carbon post, but will try gradually and see how it goes. I'm using a USE shim (which is plastic) so this will hopefully help reduce damage to the post if it does slip down.
Haven't got much choice - Bianchi use 31.4mm posts, and there wasn't a vast choice of carbon posts available at this size. Luckily I only paid £28 new for the post off Ebay, so not the end of the world if I do screw it up. Thanks for the warning though.
