Redshift Sports ShockStop suspension stem represents another option that packs some suspension into a stem that does not look much different from the one that’s probably on your bike. And there are plenty of us who turn to higher-volume tires or more supple casings to both reduce rolling resistance and add comfort to our cyclocross or gravel experience. Some use fat, shock-absorbing bar tape, others use two layers of tape or add gel inserts or wear gel gloves. Founded by a small group of mechanical engineers that happen to also be avid cyclists and triathletes, Redshift Sports aims to make components thatll. We would guess most readers will find common ground agreeing that for cyclocross and gravel, taking the edge off bumps has some value for control and reducing fatigue. Yet, we have not heard the same reactions to Katie Compton’s Front IsoSpeed-equipped Trek Boone that she’s won the last two National Championships on or the Specialized Future Shock and Fox AX Cross Fork we have also looked at. We can hear the groans and feel the eye rolls from purists and those who bounced away from past suspension designs after their run of mountain bike dominance. You can quickly adjust to dampen just the right amount of ‘road’ vibration.Suspension stems made a big splash in the UCI Mountain Bike World Championships in the 1990s, and in recent years, they have experienced a bit of a renaissance with products such as the Stafast suspension stem. Tested here is the +/-6° in 100mm.Īll-in-all, this is a great choice for a stem and with its vast adjustability, can be used as your road stem or your gravel stem. You also have a choice of 15 different firmness options as well as 4 different stem lengths for +/-6° and 1 stem length for +/-30°. This is a very simple stem to assemble and really does absorb shock from the road and/or gravel trails. It not only includes a detailed test of the SHOCKSTOP but goes into the history of suspension stems. While I was writing this review, I found this article which I highly recommend you read. But, that is what is so great about this stem, many, many possible configurations! If I would be riding the TCR Advanced exclusively as a gravel bike, I would go even softer, starting with 110 (50+60) and maybe even going to a single Black 90. For my riding, I thought the recommended 150 durometer (70+80) was a little too firm so I dropped down to 130 durometer (60+70) which worked out better for me, especially since I am still using this as a road bike. The great thing about this stem is that you can fine tune it to meet your needs.Ībove: Select your elastomers based on your weightīelow: Select the orientation that you would like your stem to be then drop in the elastomer piece(s).
With the SHOCKSTOP stem, you can go all the way down to an ultra-soft 50 durometer to an ultra-firm 170 durometer. Again, this is a recommended starting point and after a ride or two, you can swap out elastomers to increase or decrease the amount of flex resistance. At my weight of 185lbs, REDSHIFT recommended an 80 and a 70 (green and blue). Included was a +/-6° x 100mm Redshift Sports Shockstop stem.Īt first glance, the instructions seemed a little daunting, but, breaking these down into small steps, all they really were saying is to (a) select your weight then (b) match to the recommended elastomer pieces and (c) place elastomer piece(s) in TOP PART OF STEM OPENING ONLY, NEVER PLACE IN THE BOTTOM SLOTS.Įach elastomer piece has a different durometer, or hardness rating from 50 to 90. After opening the box, I laid all of the parts and directions out on the workbench.
