REDSHIFT ShockStop Suspension Seatpost for Bicycles

Product Information

I also ran a suspension fork for this year’s event, and having a bit of front and rear compliance kept me fresh and comfortable, and allowed me to pedal through rough terrain. On the rough trail, the spring seatposts are, by a large margin, the most effective at mitigating vibrations (17-24% improvement when compared to a carbon seatpost). You may need to loosen the straps slightly to accommodate the movement that occurs between road and aero positions. If your saddle bag uses rigid clips, clamps, or some other inflexible attachment method, it's possible that your bag may not be compatible. Massive adjustability lets you fine-tune your fit - extension length, armpad fore-aft, armpad width and height ( Extension Riser Kit sold separately) The other unintended consequence that occurs if the saddle position is not adjusted is that the aerobar armpads tend to be too far away to reach comfortably. You end up riding in a "superman" position with your arms extended too far forward, which puts a lot of stress on the supporting muscles of the arms, shoulders, and core.

Interesting: I used one on TCR4. It has lots of things going for it, but don’t use it any more because I found that the forward position didn’t put my saddle quite high enough and could cause knee problems. If you ride a mix of gravel and tarmac roads, I don’t know if you can do any better than the Cane Creek eeSilk. The Cirrus KINEKT 2.1 is an aluminum suspension seatpost that’s designed to isolate your body from surface vibrations and impacts to improve comfort and control. Each post comes with two extra springs so you can mix and match, creating a custom experience. The KINEKT post springs are available in five color-coded tensions for riders ranging from 50-320 pounds.The NCX seatpost features a patented parallelogram design that Suntour claims works well for small bump compliance. The post has a total of 50mm travel and was designed with low maintenance and long term durability in mind. Since ultra-distance bike races have no such rules, why wouldn’t ultra-distance cyclists want to have a seatpost that puts the saddle as far forward as possible all the time? The reason is that ultra-distance road cyclists tend to use drop handlebars with aerobars mounted to them and frequently switch between the positions. The seatpost offers the ability to switch the head around, offering more fit flexibility. Russell Burton / Our Media I have a proprietary Giant seatpost on my gravel bike, so unfortunately the Redshift post won’t work there 🙁

Lastly, we have air springs, which are sometimes used in telescopic seatposts. The main advantage is that you can adjust the spring stiffness to a higher degree of accuracy. Suspension Seatpost DesignsI am considering using the dual-position seatpost in conjunction with a Fred Bar to setup a comfort oriented aero position on a full suspension trail mountain bike (which already has a fairly aggressive effect STA at 75.5 degrees, but a long reach, as is fashionable for modern trail geometry) for a Tour Divide run.

The weight chart runs from 50-110kg, with riders over 90kg advised to use both springs, the smaller sitting inside the main spring when fitted. The system feels well-damped and there’s no noteworthy ‘bounce’ at any cadence. The saddle bottomed out a couple of times over bigger bumps; more spring compression might be useful off-road. A telescopic post is usually considered inferior, as the angle that it compresses is different from the direction of force coming from the rear wheel – resulting in a less reactive suspension system. Telescopic posts also end up with a shorter saddle-to-pedal distance when you are riding over bumps. Suspension seatposts allow you to pedal while seated on terrain that normally requires standing up. Compared to a rigid post on the same bumpy climb, I find that my legs often feel fresher simply because I’m standing up less.The eeSilk Post comes in a 27.2 diameter and is 350mm in overall length. Interchangeable elastomers allow the post to accommodate riders ranging from 100 lbs (45kg) to 330 lbs (150 kg). This is simply due to the higher percentage of weight on your saddle. Conversely, if you have more weight on your hands because you ride in a more sporty position, you can get away with less suspension travel. Best Suspension Seatposts Coil Sprung Can I use a shim to adapt to a non-round or "aero" seatpost?Unfortunately, the seatpost shim is only designed to adapt our 27.2mm round seatpost to other larger round seatpost diameters (for example, 31.6mm or 30.9mm). If your seatpost is oval or "aero" shaped, then both of our seatposts are not compatible with your bicycle. The patented Dual-Position Seatpost lets you ride a true aero position on a standard road bike, without sacrificing your normal road position. And you can switch between road and aero positions on-the-fly while riding so you can always choose the best riding position for every part of your ride.

So, you should expect to spend a few more minutes getting your preferred saddle angle right before hitting the road. The CG-R seatpost features 18mm of vertical compliance via a vibration damping carbon construction. The CG-R promises comfort and efficiency without adding weight or complication to the frame. The CG-R also has a cylindrical aluminum head assembly that adjusts fore and aft, and tilts with a single bolt. These seatposts are particularly active or ‘bobby’ in the initial part of their travel, so they tend to be better suited to rougher trails, rather than smoother roads – in my experience. If your bike has rear suspension, your saddle is already suspended so you do not need a suspension seatpost.

Many of the popular models of dropper posts used on mountain bikes don’t work perfectly unless they’re setup correctly and well maintained. Fortunately, the RedShift post is far simpler and works smoothly every time with no special setup or care needed. I appreciate you said that it takes a positive action to alter/swing the saddle position, but is there any hint of a suspension effect? There must be a small amount of give? First, why would you want to vary the position of your saddle while riding on the road? The main reasons are aerodynamics and comfort, which are both important criteria for ultra-distance cyclists. But the key difference to a carbon post is that the spring rate isn’t determined by how much exposed seatpost you have, allowing you to tune it perfectly to your body weight, using the five different elastomers available. Meanwhile, the elastomer Cane Creek eeSilk offers around half as much vibration improvement, however, it’s worth noting that it only has around half the suspension travel (20mm). It’d be interesting to see how a longer-travel elastomer seatpost compares here.
