REDSHIFT ShockStop Suspension Stem for Bicycles, Shock-Absorbing Bike Handlebar Stem for Road, Gravel, Hybrid, and E-Bikes

Product Information

All Redshift Sports components are tested to the latest ISO 4210 standard for Racing Bicycles. These standards typically specify "Static Strength" tests (i.e. one-time application of force) as well as "Fatigue" tests (i.e. repeated application of force) for different bicycle components. Redshift Sports also run our own independent tests to better understand lifespan which typically involve cycling well beyond the specifications in the ISO 4210 standard.

I’ve covered 150 miles and about 15000 ft of climbing (as what goes up must come down, the same descent). If you are unable to measure the length of your existing stem then choose 100 mm. This is one of the most common lengths and tends to be a good fit for most people.Redshift Sports spent a significant amount of time on the pivot design focused on torsional stiffness and durability. The pivot is constructed using very high tolerance full compliment ball bearings (like the ones used in mountain bike rear suspension pivots) and a high tolerance custom pivot bolt. And we are not just clamping at the pivot we are also press fitting everything together to eliminate the possibility for wear. Without wear the pivot will stay stiff and will not develop play over time.

So overall marks out of 10. Well I give the stem a really solid 9.5 out of 10. With only 0.5 mark lost for the boxy look with every other aspect full marks. Installation was very easy, if you can fit a normal stem then the only thing to think about are the elastomers, I’m 70kg so went for the blue/orange set up which was already fitted. The instructions are very clear, in fact pretty much idiot proof so long as you read them properly (RTFI) Read The Flippin Instructions. You can measure the length of your existing stem by measuring the length from the center of the handlebar to the center of the steerer tube. Come and see us!

The Price Match discount and extra discounts, club savings or promo offers cannot be applied together, we can only offer one discount. Once you determine the length of your existing stem round to the nearest 10 mm and choose the closest match. Includes 5 swappable elastomers (2 pre-installed, 3 additional) to customise the ride feel for your bike, weight, and riding style.

Well fortunately Redshift have updated the suspension stem for something more reliable, lightweight and adjustable. In general, you'll find the +30 deg stem provides a more upright, comfort-oriented fit, whereas the +/-6 deg stem puts you in a more performance-oriented riding position (standard for a typical road bike). What is the answer? Well I went for a titanium frame, fatter tyres and the thought of suspension at the front. By the start of 2018 I had a near perfect build minus the front suspension. degree in 80, 90, 100, 110, and 120mm lengths (in both standard 1 1/8" steerer and oversized 1 1/4" steerer) For looks, quality and attention to detail I will give the stem 9.5 out of 10 (.5 lost for the boxy look)

Which shockstop elastomers should I choose?

Ride faster - feeling refreshed from the energy that is normally wasted suspending your body as it is converted into forward motion mm is common on older road bikes with drop handlebars. - There are other less common sizes that we do not provide shims for. However, other handlebar shim sizes may be available at your local bike shop.
