Customer Testimonials
"I went on my first ride on the new seat post, and WOW.... It feels amazing."- Ricardo V., GA, USA
"I received my seatpost yesterday and just installed it and took a short ride. So far I am happy with it and I think it will save my boney butt. :) I feel a big difference already."- Al P., NY, USA
"Got my post in yesterday and installed it tonight. I did a quick ride and it feels great!!! What I love is that once you dial in the saddle you can adjust the suspension based on what ground you’re riding on." - Erick A., TX, USA
"Initial impressions were very positive riding down a rough and bumpy road. Doesn’t feel “springy” at all (a good thing) and is surprisingly damp. Huge props to the Redshift team." - Erick K., CA, USA
"Finally got it & installed it, WOW! Possibly the best cycling item I’ve bought since my 1st set of SPDs in 1990. I’ll be ordering one for the wife manana!"
- Tony V., Switzerland
"Well, I can honestly say, it was worth the wait! I was immediately impressed by the shock absorbing effect of the seat post. Having the combination of Redshift shock stem and seat post transforms the ride in an amazing way. Congratulations Redshift on coming through with another, well designed, revolutionary product" - Gary R.
"First ride today. Love at first bump. It’s worth the wait" - Clint M., KS, USA
"After a couple hundred of miles of gravel I have to say the seatpost is as much a game changer as the stem was. This combo has improved the ride immeasurably and still gives me complete control of the bike. I still feel the bumps and the road but the shock is gone. Seatpost took a bit of time and effort to dial in but not very difficult to accomplish. It was worth the wait for you guys to get it right. Thanks. - David N., MI, USA
