Hi

I´m about to install a Ritchey carbon Flexlogic seatpost but there is´nt a max torque indicated anywhere??...Other Ritchey carbon posts i´ve used had a 12 NM indicated on the clamp.Nothing on this one :?: .Ritchey website has the usual standard manual that also came with the post but no specific torque for the Flexlogic.I´m assuming it is 12 NM but not sure as i don´t wan´t to wreck it..
Anyone knows??

Thx

I would say call Ritchey just in case. I have dealt with them a few times, very nice and easy phone support.

The Ritchey single bolt side clamps are rated at 12Nm. I'd be very surprised if a twin bolt post was also 12Nm.
BTW what size bolts are they? M5? Side clamps are M6.

Biff?

BTW saddle rails can have max torque ratings, carbon railed especially, so that has to be taken into account as well.

Hi 585 :-)

Sorry about my late answer.

Bolts are M6.Seatpost is this "Link"-Construction...I will use the standard clamps on it though.Saddle is an SLR with carbon rails.
I did find guidelines for the Monolink adapter but nothing on the standard clamp...Weird

Surprised it's 2x M6! If you don't get official confirmation try 5-8 Nm and see how that holds.
Try forcibly moving the saddle by hand. Ideally also try it on a turbo first.

You could also put some carbon paste between the post and the clamp

I got a response from Ritchey International so i thought i would post their response in case it could be useful info:

"Dear Mr. Larsen,

the max torque allowed is 15Nm.
Please, also check with the saddles producer if the saddle rails can accept this torque.

We strongly suggest to use Ritchey Liquid Torque (or similar products) in order to increase the friction between parts even with a lower torque."


..So 15 Nm is quite a lot!.I used around 7-8 Nm which have been adequate so far.This is for the "Standard" rail clamp and not the adapter for Monolink saddles.
