Consstill a bit fiddly!
Prosmuch less fiddly than the old two bolt design
easy fit to my old aero carbon alien post, seems to grip better than the old two bolt design (which I snapped by over tightening in an attempt to stop it slipping)

ProsBetter than original 2 bolt clamp
It's necessary if from time to time you need to change saddle. The bolt is so narrow and and delicate that eventually your Allen key will round out the hex hole. The recommended torque is nothing like enough to stop the saddle slipping off if you're applying a lot of power. A brilliant seat post is ruined by a delicate fiddly clamp which needs a much more substantial bolt, no matter the few extra grams in weight it might add.

If you are unfortunate enough to own a USE seat post and are not built like a whippet then sooner or later you'll need one of these. It's cheaper than getting a new seat post - at least in the short term. 7mm is the standard size.

fizik kurve saddle USE clamp size

hi, i have a fizik kurve saddle with oval carbon braided rails, can you recommend which size USE cyclops clamp will fit this saddle? mike
Hi there,

You simply need to measure the width of the rail, and then choose the most suitable size.

Rail Width Size

What is the difference between the size 7mm and 7mm triathlon ? Does the standard 7mm rail correspond to the first one ?
Could you give me the spacing value of each one to let me identify the one I have to order ?

The first 7mm option is for standard 7mm saddle rails, the spacing for both is still 43mm the Triathlon version is just designed for saddles rails that are 7mm wide but sit slightly taller.
