Reviews of Problem Solvers 3.2mm Shim, 25.4 Seatpost to 28.6

Customer Ratings:

When you buy these one at a time they are way too expensive. Can somebody please sell bags of 5 or 6 together ?

I had a saddle I liked and an expensive CNC alloy seat post left over from an old bike project, and wanted to use the combo on a new project based on a different frame. Problem was that the new frame had a larger-diameter seat tube than the old frame. Sure, I could have bought a new and equally-expensive (approximately $30) alloy seat post of the right diameter; but I'm a thrifty guy. So, I looked around and found this adapter. I forget exactly what it cost (about $5, I think). I could have cut up some aluminum beverage can to make a free shim, but it would have looked cheesy and been mechanically questionable. This shim is solid and reliable.

This shim is beautifully designed and made. It has a lip at the top to prevent it slipping down when the clamp is loosened to adjust seat height. It also serves as trim to conceal the top edge of the seat tube, which usually would show chipped paint and rust. The visible part of the shim is a perfect match for the alloy seat post it surrounds, making it more attractive than a right-sized seat post would be. Highly recommended.
