Burgtec Xpress Post Alloy

The Xpress Alloy gives a mountain bike a straightforward 300mm seatpost with a laser-etched finish. Burgtec uses 7075 aluminium here, making it a distinct choice from the UD Carbon Xpress when you're finishing the build.

The two options are 30.9mm and 31.6mm post diameters. Match that diameter to your frame; it isn't the size of the clamp around the outside of the seat tube.
