Review by Biking Joe

Great seat post solving a fit issue
by Biking Joe

My build creates fit issues on getting a comfortable efficient position on bicycles without getting custom frame. This bike post solved 2 issues. 1. 0 degree offset Allowed seat be positioned correctly for my knees over crank by having enough seat rail to move seat forward enough and still centered on rails. 2. Post has 2 set screws to keep seat in comfortable up or down position for riders comfort/preference. A bonus of these set screws, is location. Adjustable very easily with access in front of post. I have had issues with Single bolt seat posts not keeping seat level after I set. Seems you hit the wrong bump and seat goes out of position. I could not justify the price difference doing the carbon model of this seat post, A couple grams saved is expensive. It is on a checkpoint so has a decoupler to smooth ride. I have had good experience with Easton products ince the 1970's.

Good quality. Easy adjustments!

I bought this mainly to make saddle adjustments a lot easier than my old seat post and this delivers exactly that. One bolt to move the saddle fore/aft and a separate bolt to adjust the angle of the saddle. Both work great and hold very strong once properly torqued. The setback provides a bit more compliance too and makes it more comfortable on longer rides.
