I purchased this shim to mount a 27.2mm suspension seatpost on my mountain bike that requires one that is 30.9mm. It fits perfectly and allows proper tightening of the seatpost.

Honest reviews on Problem Solvers 3.7mm Shim, 27.2 Seatpost to 30.9

This is awesome, I upgraded my xc frame to an all mountain frame, and seat-post diameter increased from 27.2 to 30.9...

Instead of having to sell my old seatpost and purchase another one at a hefty cost, I found the "problem solvers" shim to save my day.

It works great, 100mm of length made sure my seatpost sit in nice and snuggle. Once clamped, it is very secure just like a 30.9mm seatpost.

Save yourself some money and get this if you want to reuse your old seatpost!
