Really nice quality seatpost. A bit stiffer than my other carbon post but more confidence inspiring. The seat clamp is the best I’ve used. Great price and service from Tweeks

Sean Taplin 30/06/2023

Very lightweight, nice finish with subtle graphics. Well designed single bolt clamp - welcome improvement over the cyclops clamp.

Michael Clarke 23/10/2023

I’m using this on my road bike. I bought the 400mm but 300 mm would have sufficed. Easy to install with variable seat angles. I used carbon paste and a torque wrench whilst fitting.
