SKU code: SHM-PRAC0224
In Stock
A clean, secure way to lock in your saddle height. This PRO 2-bolt seatpost clamp uses a CNC-machined alloy body and twin bolts to spread clamping force evenly, holding your post firmly without crushing it - making it especially kind to delicate dropper and carbon posts.
Highlights
- Even, secure hold from a balanced 2-bolt design
- Dropper- and carbon-post friendly low clamping torque
- Lightweight CNC-machined 6061 aluminium body
- 31.8mm (27.2mm post) and 34.9mm (30.9 / 31.6mm post) clamp diameter to suit 30.9mm and 31.6mm seatposts
- Discreet black finish that blends with any frame
Why a 2-bolt clamp
Two bolts distribute pressure more evenly around the post than a single-bolt clamp, giving a confident grip at a lower torque. That gentler, more even squeeze helps protect the outer surface of the post and the internal mechanism of adjustable dropper posts.
Built to last
The body is CNC-machined from 6061 aluminium for a strong, lightweight clamp that resists slipping and stands up to repeated adjustment.
Compatibility & fit
This clamp has a 31.8mm (27.2mm post) and 34.9mm (30.9 / 31.6mm post) internal (clamp) diameter, sized to fit a 31.8mm (27.2mm post) and 34.9mm (30.9 / 31.6mm post) seat tube and to clamp a 30.9mm or 31.6mm seatpost. Check that your frame's seat tube clamp area measures 31.8mm (27.2mm post) and 34.9mm (30.9 / 31.6mm post) and that your seatpost is 30.9mm or 31.6mm before ordering. Tighten gradually to the post or frame manufacturer's recommended torque to avoid damaging the post.
Options
Available in 2 diameters: 31.8mm (27.2mm post) and 34.9mm (30.9 / 31.6mm post). Select yours from the dropdown above.
