REDSHIFT ShockStop Suspension Seatpost for Bicycles

Product Information

Due to the vertical flexibility of 35 mm, it is suitable for almost any type of bike with a seat tube inner diameter of 27.2 mm Bikes with a larger diameter can be adjusted with an optional reduction sleeve. At 150lbs, initially I went with their recommendation of the Main Spring only with preload at #3. This was way too soft in my opinion, especially for more spirited riding. The next step was to increase the preload with just the Main Spring. Eventually, I cranked it up to 4 which is the maximum recommended preload setting with just the main spring. It was better, but I found that it resulted in a ride that was still a little too active, and it was more prone to ‘topping out’ with a thud in certain situations. Then I built up a new gravel beast and thought, hey, why not upgrade the seatpost as well. I retired the Thudbuster and sprung for a Redshift (pun intended). I’ve been on it for a month now and there are no downsides. I’m 175# and this post is perfect. I run it slightly soft and it keeps me planted through the big hits and eliminates most of the medium chatter. Small stuttery garbage is gone. The return rate is immediate and so I’ve had no issues taking this bike on the concrete. Yesterday, on a whim, I took this bike on a group road ride and was in the front the whole time. I’ve experienced no penalty for running the Redshift post on the road! ktache : My Cane Creek ThudBuster ST has been excellent. Only 1 1/3 inches of travel, but takes the edge off off road and is plush on. Did think about the long travel, but my seatpost is fairly full and I wouldn't have been able to drop it for the going down bits. The ST is a bit lighter than the Suntour. I used an Argon 18 Dark Matter gravel bike for this test. The bike was set up with Challenge GravelGrinder 700C x 42mm tires.

It’s constructed from FACT carbon fibre to a 27.2mm diameter with a cylindrical aluminium head for easy saddle adjustment.Heading out the door?

To determine the spring stiffness, choose between installing just the main suspension or combining it with the included additional suspension. The preload can be adjusted by hand on the underside of the seat post. Are you looking to add more comfort to your ride? If you ride a rigid gravel bike for example and want some more suppleness. You could reduce the tire pressure and even change over to suspension gravel forks. But a cost effective way is to install a suspension seatpost. Adjustability: 7 out of 10. While both the seat angle and the suspension properties are adjustable, they do require tools and, in the case of the latter, removal of the seatpost from the frame.

The CF Allroad Pro feels less like competing suspension seatposts offered by Redshift and Cane Creek and more like you’re running a higher-volume rear tyre. Less chatter and vibration makes its way from the road to the rider, with minimal movement to distract you from the task at hand. Suspension seatposts are available with anything from 20 to 90mm of travel. So, how much travel is best for you?The clear and concise instructions suggest positioning the saddle 5mm further forward and 6mm higher than with a rigid post to account for the initial sag when sitting. Along with the suggested spring force setting, made by turning a threaded plug in the bottom of the post to compress the internal spring, this proved accurate to the point where no further adjustment was needed.
