$167.95
Ritchey's WCS seatpost comes in two builds on this listing: a zero-offset post with a 2-bolt fore/aft clamp, and a 20mm-offset post with a single-bolt head, both 3D-forged for a stiff, light result.
Highlights
- WCS Zero: zero offset, 2014 alloy, 2-bolt fore/aft clamp for fine saddle-angle adjustment
- WCS 1-Bolt: 20mm offset, 7050 alloy, single-bolt head with a 7x7mm rail clamp
- Available in 27.2, 30.9mm (both builds) and 31.6mm (WCS Zero only, on this listing)
- 400mm length on WCS Zero, 350mm on WCS 1-Bolt, both with a 100mm minimum insert
- 3D-forged aluminium construction on both builds
Two builds, two offsets
Pick WCS Zero for a neutral saddle position with micro-adjustable fore/aft, or WCS 1-Bolt for 20mm of setback with a simpler single-bolt clamp. See the options table for the exact spec of each.
Compatibility & fit
Choose the diameter that matches your seat tube. Minimum insertion depth is 100mm on both builds. The Tune workshop can set saddle angle and torque the clamp to spec.
