What are the ShockStop stem features?

The information given below is a shorter version of our comprehensive Redshift Sports shockstop stem review and FAQ

The stem has been designed to reduce vibration through a clever elastomer suspension system. As with all suspension systems, a bike fit may be the best solution to your ailments, but this suspension stem is your best mechanical solution. The Shockstop aims to improve:

  • Comfort - Reduce shock and vibration transferred to your hands and wrists. 
  • Ride faster and at the same energy level over rough, uneven roads.
  • Energy - Your body absorbs less shock, saving energy and less fatigue.
  • Control - Focus on the road instead of dodging bumps and cracks.

Why do I need a Shockstop stem?

  • Bikes should be comfortable, but ride more than a few miles and you realize very quickly that bikes are stiff, and they transmit every little bump straight to your hands and arms. After a while those impacts and vibrations make it hard to enjoy the ride.
  • The ShockStop bike stem does what gloves and extra bar tape can't: it isolates your upper body from the imperfections of the road, letting you ride further, faster, and more comfortably.

Who has the Shockstop been designed for?

ShockStop is designed from the ground up specifically for road and hybrid bikes - the suspension travel, weight, feel, and aesthetics are finely tuned to perfectly complement modern bikes and the roads we ride on.

How does the shockstop work?

The ShockStop dramatically improves the quality of your ride, without compromising steering responsiveness or detracting from the aesthetic of the bike. The subtle pivot design allows the front end of the bike to move up and down over bumps in the road while your hands follow a smoother path, cushioned by the elastomers inside the stem.

Took a dip at this for £140 as I was close to parting ways with my supersix.First impressions are you expect more until you realise it's working all the time at reducing vibration through to your hands.Due to riding on poor road surfaces in UK this along with heavier wider tyres will transform your ride.Descend faster ,no bobbing whilst climbing and no tingling hands anymore.Roads which I usually avoid are now rideable.

A great stem from Redshift Sports. Kit Radar..... surely you can do better?

I have the Redshift Sports stem fitted to my fast daily-ride, based around a Kona steel fixed gear frame with a carbon fork and 28c road tubeless tyres on a light and stiff fixed gear wheelset built by DCR Wheels.( The stem has made the bike a blast to ride fast on the worst of urban tarmac, with the ability to hold the fastest line especially in sustained out-of-the-saddle efforts. Highly recommended.........!!
Before purchasing the stem, I emailed Redshift Sports in the USA - Alex from Redshift replied very promptly and his answers to my technical questions showed his in-depth knowledge of all aspects of the ShockStop Stem. In contrast, the product enquiry email I sent to Kit Radar went unanswered. Following on from that, the stem that I ordered from Kit Radar was dispatched quickly. I received it in a strong, well-taped cardboard box. Oddly, the stem in it's Redshift packaging, was left rattling around inside (ie. no additional protective packaging material). In my experience, that would be an unusually poor way to ship an item with a cost of £140.00.
A final observation would be that Kit Radar's website showed the stem fitted with sleek, black taper head bolts and washers on the face plate and rear clamp. The stem that I received came fitted with very industrial-looking silver cap head stainless steel bolts and over-sized steel spring washers. I have changed the bolts for black hardware, which hugely improves the aesthetic of the stem, particularly if it is to find a place on a fast road or fixed gear bike.
