Diameter of Front Mech clamp for Ridley Orion

remi_m

Hope someone can help..........

I have just got a Ridley Orion frame and am about to order a Ultegra SL groupset and wasn't sure what diameter mech clamp to order. Any help would be appreciated.

Cheers

Wrap a piece of paper round it and mark it with a pencil. Then measure the paper with a ruler in milimetres.

It will either be 34.9mm, 31.8mm or 28.6mm. So with a pencil and paper you can afford to be milimetre out and still be close enough to order the right one.
