PRO 2-Bolt Seatpost Clamp (27.2mm Post / 31.8mm Tube)
SKU code: SHM-PRAC0224
Sold Out
Hold your saddle height secure with a clean, two-bolt clamp that grips evenly and stays put on rough roads and trails. The twin-bolt design spreads clamping force around the seat tube for a confident hold, and the controlled torque keeps your seatpost (including dropper posts) safe from over-tightening.
Highlights
- Even, secure hold from a balanced two-bolt clamping design
- CNC-machined 6061 aluminium for a light, durable finish
- Low recommended torque protects the seatpost and dropper internals
- Sized for a 27.2 mm seatpost in a 31.8 mm seat tube
- Discreet black finish to suit most frames
Why two bolts
A two-bolt clamp distributes pressure more evenly than a single-bolt design, giving a reassuring grip without needing to crank the bolts tight. That matters most on bumpy terrain and with dropper posts, where slip and over-clamping are common frustrations.
Built to last
The body is CNC-machined from 6061 aluminium, keeping weight low (around 25 g) while standing up to everyday riding and the elements.
Compatibility & fit
Designed for a 27.2 mm seatpost fitted into a 31.8 mm seat tube. Check both your seatpost diameter and your frame's seat tube clamp diameter before ordering, as a mismatch will not hold correctly. Suitable for use with adjustable dropper posts when set to the recommended tightening torque of 4 Nm.
PRO components are covered against manufacturing defects in materials and workmanship. The warranty does not cover normal wear, crash or impact damage, or issues caused by incorrect fitment or over-tightening beyond the recommended torque.
