    Bought this post because of the AWFUL Chicago streets, and I am overjoyed at it's performance. I love that it is adjustable, feels extremely well-made, and enhances the look of my e-bike. Thank you for such a thoughtful product, my butt especially thanks you.

Money well spent!

  • William S

    This is a great addition to my gravel bike. It took a few adjustments to get the right elastomers but, it definitely smooths out the ride. Will be purchasing a set for my road bike.

  • Scott C

    This seat post is a game changer!! Absolutely love it on my gravel bike .gonna get one for my hard tail Mtb now

  • TD

    Love the stem!! It really takes out all the worse bumps from your ride, and on rough trails really did offer a smooth comfortable ride.

  • Lawrence C

    I hesitated buying this stem wondering would it work, was it a waste of money but I’ve had three off road rides with my new stem and I love it. I usually get pins and needles in my hands after riding for a while but that’s gone now. Added to the comfort is the improved handling on bumpy tracks and roads. I can ride a corrugated road now without feeling like I will get shaken off the bike. Very happy.

  • Jim G

    I love my Redshift post! I recently had a lumbar contusion and the post has smoothed and cushioned the roads and trails. I’m able to stay on the bike while healing.

  • Ian S

    After much thought I bought a red shift suspension stem and initial thoughts are that it's good, think they will become standard across all my gravel bikes.

  • Stephen H

    I just finished my first ride with the Resdhift Shockstop Suspension Stem and I noticed the difference immediately. Having ridden for many years with rigid front ends (I’m 64) I now wish I had discovered this earlier in my life. The chatter that it removes from my wrists, arms and shoulders is easily noticed. This experience has been so good that now I’m considering the seatpost Redshift offers as well. The interesting thing for me is that I’ve promoted and sold these products for years based upon input from others. I just didn’t think I needed one myself. Get yourself one! You’ll never go back.

  • Mark G

    The shock absorber was easy to install and works as described cuts down on the impact. I recommend it if you're going to do gravel, writing and bumpy bumpy roads

  • Karlos R

    Wow, once I got the fit dialed on this seat post I thoroughly understood why everyone was upgrading their set ups with these products. Riding a long distances is what I do for fun and for a living and this seatpost made all the difference in the world. Pay attention to the recommended Sag settings as its key to finding comfort and keeping a proper pedaling extension. 10 out of 10 would recommend.

ACIERTO DE CONFORT

Actúa más directo al cuerpo que una amortiguación trasera, tenemos un grupo con el mismo modelo de bici e-gravel y después y después de probarlo les ha convencido notablemente, el único pero es el precio.

Smooth as...

It’s a beautifully engineered piece of kit that does what it says - stops the shock! When I step back on one of my other bikes (without Shockstop), I notice myself subconsciously bracing with my legs as I go over bumps to try and absorb the shock. Not so with the ShockStop - just ride over them and it takes them out! Fantastic product.
