The PRO Alloy Seatpost Clamp is a simple 1-bolt, hex-key seatpost clamp for riders who want a tidy, reliable replacement for a worn or damaged collar. It gives you alloy construction, a stainless steel bolt and nut, and three common sizes, so it suits plenty of road, gravel and MTB builds that use a standard external clamp.

If your current collar is tired, corroded or no longer holding saddle height properly, the PRO Alloy Seatpost Clamp is an easy fix. It uses a robust alloy body with a single stainless steel bolt and nut, plus hex-key actuation for a clean look and dependable clamping on bikes that use a conventional external seatpost clamp.
This is the kind of part that suits riders who just want a simple, workshop-friendly replacement rather than a flashy upgrade. The three available sizes — 28.6 mm, 31.8 mm and 34.9 mm — cover some of the most common round seat tube standards, and the black finish keeps things neat on almost any build.
The main thing to get right is sizing and seatpost material. This clamp is intended for aluminium seatposts only, so it is not the pick if your bike runs a carbon post. As with any seatpost collar, correct fit matters more than brute force: measure the outside diameter of the frame’s seat tube at the clamp, not the seatpost itself, and install it with the right assembly compound for your frame and post materials.
Ideal for riders replacing a worn stock seatpost collar on a bike with a standard round seat tube and an aluminium seatpost.
Alloy construction
A solid metal clamp body built for everyday use on commuter, road, gravel and MTB bikes with a standard external collar.
Hex-key actuation
Cleaner and more secure than a quick-release style if you prefer a tidy setup and rarely change saddle height mid-ride.
Stainless steel bolt and nut
Durable hardware that is better suited to repeated adjustments and general weather exposure than basic plated fittings.
Single-bolt design
Simple to fit, easy to service and quick to adjust with a standard workshop hex key.
Three common sizes
Available in 28.6 mm, 31.8 mm and 34.9 mm to suit a wide range of bikes using round external seatpost clamps.
Black finish
Easy to match with most frames and finishing kit for a clean, understated look.
Replacement-friendly format
A practical choice when your original clamp is slipping, cracked, corroded or missing hardware.
