Ritchey Classic Alloy Seatpost – 27.2mm, Zero
SKU code: DTW-RIG-SPCLSZ04272S
$130.96
Ritchey's Classic brings the brand's signature high-polish silver finish to a dependable, infinitely-adjustable alloy seatpost, available with either a 25mm-offset 2-bolt clamp or a zero-offset fore/aft clamp.
Highlights
- High-polish silver finish
- 25mm-offset version: 2014 alloy, standard 2-bolt clamp, 13Nm max clamp torque
- Zero-offset version: 6061 alloy, 2-bolt fore/aft clamp, 7Nm max clamp torque
- 27.2mm, 30.9mm and 31.6mm diameters
- 350mm or 400mm total length (including 100mm minimum insert)
Two clamp styles
The 25mm-offset post uses Ritchey's proven 2-bolt design, low-profile and easy to adjust. The zero-offset post uses a 2-bolt fore/aft clamp instead, securing the rails directly under the saddle for riders who need the seat forward rather than set back.
Compatibility & fit
Choose the diameter that matches your frame's seat tube (27.2 / 30.9 / 31.6mm) and the offset your fit needs. Minimum insertion is 100mm — never ride below the post's marked minimum-insert line.
