At the suggested preload setting, I immediately felt neutrally suspended and didn’t notice any negative effect on seated pedalling. The small unweighted saddle height increase needs a slight adjustment when mounting up for the first time. When weight is added to the post a link compresses the internal spring(s), creating user-adjustable sag, which Redshift recommends should be around 20 per cent of the 35mm total travel. Its two-bolt saddle clamp remains level atop a parallelogram linkage pivoting on dry-lube bushings.

Turn the preload plug to the required position and fit the post. Numbers one to five are printed within its thread pitch and relate to rider weight and the spring(s). With the main spring fitted, my unit weighed 538g.Ī preload adjusting plug in the base of the seatpost tunes the suspension.

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. Its larger main spring is pre-installed and a smaller diameter inner spring is supplied – to be fitted within it if a stiffer spring rate is necessary. Tech detailsĭeveloped together with Redshift, you get the same tunable ride feel with two of 5 different interchangeable elastomers inserted into the stem to suit rider weight or riding style preference.īMC’s solution though is a bit wider and boxier for improved stiffness, spins on wide-set sealed bearings, and also includes BMC’s integrated faceplate GPS/GoPro out front mount.Unlike existing designs, the Shockstop uses springs to provide its suspension. More comfort for longer rides over rougher terrain, in addition to the benefits of lower-pressure, high-volume tires. All that while allowing for split spacers to adjust stem height as needed and using a conventional bar to ensure hand position adjustability. What’s really new is the way the BMC stem tucks cables out of the way inside an integrated cover just below the stem body, and then directs those cables inside the steerer tube or frame via custom steerer spacers that seamlessly transition into the headset’s upper bearing cover. Thus, the BMC ICS MTT suspension stem combines adaptable compatibility with integrated cockpits and up to 20mm of elastomer travel at the bar to complement the 10mm of MTT elastomer travel in the back of the URS or also the 20mm of coil-sprung HiRide front suspension of the URS LT gravel bikes. What’s new?īMC’s gravel suspension stem take the names of two of their existing technologies – Integrated Cockpit System (ICS) & Micro Travel Technology (MTT). When we reviewed it two years later, we were pleasantly surprised at how good it is.īut now everyone has gone aero and cables have been integrated – with BMC leading the charge – so they decided to work together to make an even more-modern gravel suspension stem. But Redshift did it better, and it seems to make a lot more sense on all-road & gravel bikes than it ever did for serious mountain biking.

When reimagined by Redshift in 2015 it was already an idea we’d ridden for over twenty years. Look, the ShockStop suspension stem concept isn’t new. BMC ICS MTT suspension stem x Redshift c. If it looks familiar to you, then you’ve been paying attention, because it is essentially the exact same proven Redshift ShockStop stem tech, combined with a BMC faceplate and tidy, semi-integrated cable routing to clean up your cockpit.

BMC quietly combined aero integration and gravel comfort this summer with their new ICS MTT suspension stem, just after they dropped the new Roadmachine AMP.
