This shim lets you run a 25.4mm seatpost in a larger seat tube, matching the post you have (or want) to the frame you're fitting it to.

Compatibility & fit

Inside diameter is fixed at 25.4mm; choose the outside diameter that matches your frame's seat tube. Seatpost diameters are stamped or laser-etched near the top of the post's maximum-height line – check this before ordering, as shims can't be returned once picked and packed. Cane Creek lists these as suiting rigid, suspension and dropper posts.

Cane Creek covers this shim against manufacturing defects; as a simple fit part, general wear isn't a warranty matter and it can't be returned once fitted. For warranty support, return the product to Tune Cycles and we'll manage the claim with Cane Creek's Australian distributor. This is in addition to your rights under the Australian Consumer Law – keep your proof of purchase.
