degree in 80, 90, 100, 110, and 120mm lengths (in both standard 1 1/8" steerer and oversized 1 1/4" steerer)

The downside to elastomers is that they can firm up in cold conditions, rendering them less effective – so, skip this design if you need it to work well in sub-zero conditions. I’ve also found they require lubrication around the edges of the elastomer, although this maintenance is essentially solved with a simple seatpost cover. The PNW Coast is an air-damped dropper suspension seatpost. Continuing their 20-year suspension seatpost legacy, Cane Creek recently announced the all-new, fourth generation Thudbuster ST (Short Travel). Designed with touring, commutes, and e-bike trips in mind, it features 50mm of travel—up from 33mm on the original Thudbuster ST—to smooth out bumps and bounces on multi-surface rides. Building on the original Thudbuster’s parallel linkage, it also got a redesign for a higher rider weight limit (now up to 330 pounds), increased durability, and more travel. 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. Redshift suggests that riders up to 80kg should only use the main spring and those from 90kg to 110kg must install the inner spring as well. With the main spring fitted, my unit weighed 538g.A suspension seatpost allows you to take bikes with narrow tyres on much rougher terrain than you normally could. Obviously, this isn’t an ideal situation, but you’d be surprised how off-road you can go on 38mm tyres! Krzysztof over at GravelBikes.cc has been using his smartphone with a vibration meter app to compare the vibration absorption of different bike components on both a bumpy forest trail and fast gravel road. Overall, I'm a big fan of this seatpost. I can overlook the weight issues purely because of how much adjustability it has, and the suspension action is just so smooth. It is really easy to tweak and set up, too, even out on the trail. Verdict Also it is worth noting that some suspension seatposts can have changes in the saddle to pedal distance, and that can be hard on come people knees, potentially causing issues. Are suspension seatposts any good? I did find that the neoprene cover (expensive for what it is) took away some of the rattle when the seat was not loaded.

Disfunctional_Threshold : I have the Syntace P6 Carbon Hi-Flex seatpost. I've never been able to detect any flex in it at all. I've recently bought one (Suntour SP12-NCX) and I'm super impressed - I ride mainly on the road in Devon, where the surfaces aren't exactly smooth. What really counts is everyday comfort. And the Redshift suspension seatpost definitely delivers that. We’ve seen the explosion in recent years of endurance road bikes designed to provide smoother rides through the use of modified carbon fibre layups, tube shaping or elastomer inserts. They’ve been very popular with cyclists who value speed and performance, but want a smoother ride, especially given how bumpy and rough roads in the UK generally are.With the knowledge that my tyre volume and pressure could cope with the sort of impacts I normally try to avoid, I steered towards the roughest patches of tarmac, potholes, ancient cobbles and uneven gravel. He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history. If you suffer from fatigue on bad roads and lumpy gravel, the PRO should keep you fresher for longer. Measure your current seatpost from the clamp collar to the saddle rail and refer to the chart above to choose your preferred size. I *think* my knees are happier for getting rid of the suspension seatpost also, it seemed to be aggravating some ITB syndrome or something in my left knee, but perhaps I just never got the saddle position right.
