Review: Superb - Having read a number of reviews of the Redshift Endurance Seatpost (and having tried telescopic seatposts), with reviewers noting how it greatly improves the comfort of riding, I was persuaded to buy one. All these claims of comfort are fully justified: this seatpost really is excellent. Initially, I bought one for an electric bike (30.9mm), which was such an improvement on the rigid post that I bought a second for a non-electric hybrid bike (27.2mm). As many others have observed, the seatpost smooths the ride over bumps to the extent that they become simply undulations and not a bone-jarring experience. There are a range of rider weight-related settings, adjustable for comfort, helpfully listed (as a starting point for fine-tuning) in the seatpost's instructions. In terms of softness, the aim is to ensure there is no excessive 'bottom-out' when riding over uneven roads/tracks. The settings I've used are based on my weight with the rucksack (toolkit; spare inner tubes; etc.) I carry on all my rides: 84kg. 30.9mm seatpost setting: '4'; 27.2mm seatpost setting: '3.5'. Highly recommended.
Review: Comfort at last 😊 - This seat post is a game changer for me... Comfortable for miles and miles... Brilliant piece of kit 😄

### ⭐⭐⭐⭐⭐ Smooths out small bumps and helps a lot with bigger ones!
*by M***T on 8 February 2022*

My road bike already had headset suspension for the bars which helps avoid numb hands, but with country roads around here being so damaged, I was looking the something to help soften the shocks at the back too… The Shockstop seatpost is clearly very well and thoughtfully engineered, and that’s clear both as you take it out of the box and if you watch the detailed and thorough installation video that Red Shift have put on YouTube. The most fiddly aspect of installation is probably swapping the saddle over from your old seatpost but it’s really not tricky at all. To get the best out of it, you need to adjust the ‘preload’ for the spring (or rather springs): too soft and you’ll bounce a little too much when pedalling hard. Too hard and you won’t get enough benefit for smaller bumps. This is adjusted by turning a large screw at the bottom of the Shockstop seatpost - you can use a small screwdriver or Allen key if it’s too stiff for your fingers. There’s a guide in the box for an initial setting according to weight, but it’s more of an art than a science and the right setting will also depend on what type of surfaces you mostly ride on and your posture on the bike. Heavier riders (myself included) will need to use both of the included springs to be able to set the correct preload. For me, it took another two tweaks after installation to find the perfect ‘Goldilocks’ preload for me and my bike. And the result is great! Before getting this, I would definitely think hard before doing all but the smallest rides without padded bike gear, but this honestly adds enough comfort for trips to the shops or pub in normal clothes without your bum complaining. ;) It’s not a miracle cure for bad roads, but it makes a bigger difference than I would have expected and for me at least - who rides for fun and exercise rather than racing - it’s well worth the extra weight for the massive boost in comfort especially over longer rural rides.
