Aluminum Alloy Bicycle Seatpost 100mm

I needed to fit a REDSHIFT ShockStop Suspension Seatpost onto my Eahora X7 folding electric bike and the Ganopper 27.2 to 33.9 worked perfectly!The suspension seat post works perfectly, but I couldn't have used it without this shim.Thank you!!

Take a file and grind a chamfer on inside radius of top flange as shown in pics. For good measure a filed a chamfer with square file down the slor as well. When I first installed the collar I noticed small flakes from my post where the sharp edges were digging into my post as it flexed.

This adapter worked perfect for my bike. I wanted to put my cruiser suspension seat post on my new bike and this adapter works great with no issues.

It fit perfectly no issues great product.

The inside finish was to smooth to hold seat post up to height. Inside finish should be finished same as out side finish. I just used heavy grit sandpaper and scuffed it up to give it some grip on the post.

Swapped a 27.2 dropper post from my daughter's old bike to her new one, with a 31.6. This adapter filled the gap. No issues after 6 months or so.

This worked well to install a dropper seat post in a 30.4mm bike. I preferred the longer length over some of the others I found, figuring it will provide more stability and grip. It was very well made.

Perfect for my Aventon Aventure sleeve was long enough to support my Suntour Seat post

Wanted to try a suspension seatpost but it was to narrow. This shim did the trick. Not a fan of the suspension seatpost I tried, maybe an elastomer one would work better, but shim held.

No sirve para nada me lo mandaron inexacto o da y no corresponde a las medidas que enviaron. Lo enviaron tal cual lo pedi pero, mal hecho o rquivocado de medidas hay que fijarse y medir cinco veces y mandarlo . Que es solo UNA…

Quality product know you size.

Perfect fit

Awesome
