What to Compare Before Buying

Compatibility, Size and Fit
This clamp is for the 31.8 mm seatpost version. The product text also refers to a 34.9 mm seatpost tube for this model, so the seatpost and tube sizes need to be matched carefully before purchase.
Because this part replaces the seatpost clamp, the exact diameter is the key fit check. Measure the seatpost, not only the seat tube, before choosing an offer.
What Else You May Need
You will need a rear carrier that matches the two M5 threaded eyelets if you are using the clamp as a rack mounting point. An allen wrench is also needed for fitting.
Before You Decide
Confirm the 31.8 mm seatpost size before choosing an offer. Check that the added M5 rear threaded eyelets suit your rear carrier fixing. Make sure you are happy replacing the existing seatpost clamp and fitting the part with an allen wrench.
