Seat Posts

The correct seat post diameter is essential. To check which size you need (assuming you have your old post), pretty well every post is stamped with the diameter just under the minimum insertion line (in the bottom 100mm or so). If measuring a post or frame, use vernier calipers and take several measurements at different angles to allow for distortion.

Cane Creek Thudbuster LT 27.2mm

!

This is probably the best suspension seat post. Long, adjustable, durable, ugly. Comes with a variety of elastomers, all in a nice box.

Or in Cane Creek's words:

"By adding the Thudbuster rear suspension you'll ride faster, longer, and stronger with better traction, more control, and less fatigue. The performance, relative low weight, and simplicity make it the best suspension upgrade you can make to your hardtail.

Based on a patented parallel-linkage design, the Thudbuster LT provides up to 3 inches of active stiction-free travel. Unlike telescoping suspension posts, there is no initial stiction to overcome—the suspension mechanism works in the direct path of the natural travel of the rear wheel.

The elastomers provide the compression and rebound damping, and can be easily exchanged to tune the suspension. "

Forged aluminium post. Machined aluminium linkage. Stainless steel pivots with Teflon coated bushings. Twin urethane elastomer stack with various spring rates. 3 inches (76mm) travel. 396mm long (446mm in the XL version in 27.2mm only). Extension from seat tube exit to centre of saddle rails: Minimum 144mm, Maximum 296mm. 346mm in the 27.2 XL version). Diameter: The Australian distributor stocks only 25.4mm and 27.2mm. But if you're willing to wait, say, a month, they can also get 26.8, 27.0, 30.9, 31.6. Also, using the Cane Creek shims from either the 25.4 post or 27.2 post you'll fit pretty well anything. Black.
