Ritchey WCS Alloy 1 Bolt Clamp is rated 4.9 out of 5 by 19.
Rated 5 out of 5 by from Great Product Was a little dubious about ordering this due to differing sizes of rails and stems. However worked out to be great. Easy to use and strong bit of kit for saying how small and light it is.

Rated 5 out of 5 by from Perfect purchase The ritchey 1 bolt system is fantastic, best I have found to date. One hand on the Allen key, the other free to adjust and steady the sadle. I upgraded to carbon rails on my sadle and needed the larger clamp. Easy to swap out and set up. Usual great service, price and delivery from Wiggle

Rated 5 out of 5 by from Works great on Carbon rail Tundra 2 seat Was easy to replace the 7mm clamp with the 9.6 clamp and held rail of carbon seat firmly. Note it was around 10 grams heavier than the 7mm clamp

Which clamp size do i need for Ritchey Streem WCS Carbon saddle and Ritchey WCS Alloy One Bolt Seatpost?

Hello, wondering if this is the right product to order. The standard clamp that came with my sadlle doesn't seem to hold the saddle properly. I have two shells that came with the seatpost but I don't see those working either.
Asked by: FlorianS
For this saddle, the the 7 x 9.6 mm option should be suitable for you.

what size for a selle italia thoork team edition carbon rails? how can i tell the rail size? want to avoid an exchange if i can. thanks

Asked by: bigchap3
Carbon rails are bigger than standard rails, so only specific clamps will work with carbon rails. This clamp should be compatible with your saddle.

The difference is that one is made from carbon and the other is made from alloy but both are compatible with the size of carbon rails.

Difference between "Alloy one bolt" and the "Carbon one bolt" clamps??

Can the Alloy version for Carbon rails (which I believe is Black in colour) be used with a Carbon seatpost or does this have to be used on an Alloy seatpost?? Or do I have to use the Carbon clamp (which I believe is the silver one) with the carbon post? Most websites including Ritchey, suggest that the Carbon version is silver however, your site states that the Carbon clamp is Black?? Ideally I want the Carbon clamp to be Black as it would look better on my Black bike. Many Thanks
Asked by: ScreaminWargasm
I can confirm that both of these 1 bolt systems are designed for carbon rails but one is designed for carbon seat post where the other is designed for allow seat post. I hope this helps.
