RedShift ShockStop – A vibration damping bike stem – KICKSTARTER

Some KickStarter Projects look too good to be true. By comparison, some produce a knee-jerk “Why didn’t I think of that!” In this case RedShift has produced an “I NEED one of those” reactions. Anything that looks like it will reduce the vibrations going up through my arm gets my vote. Read on to see what I’m going on about!

So after having broken my arm, even though I’m cycling again, my RIGHT side is weaker than the left. Couple with large rough patches on the road can really make my RIGHT elbow sore after an hour on the bike. Thus seeing the RedShift ShockStop, I was immediately interested.

But what is it??

ShockStop is an adjustable-stiffness suspension stem, reducing the vibrations and jarring knocks than can get transmitted to the rider on the road. It works through having an elastomer within a joint at the stem allowing vertical movement – which in turn smooths the ride, whilst not affecting lateral movement – i.e. your steering input.

I’ll be honest, my first thought was the Trek IsoSpeed decoupler when I heard about the idea.

IsoSpeed decoupler

 

If I’m honest I think that RedShift’s own gif image does a very good job of explaining its function:

Bounce!

 

The above gif, the pivot design looks like there is quieten lot of movement, which initially looks a little excessive. But the stem is designed to come with different elastomers to allow you to fine tune the amount of movement you get. Certainly I’d like it a little stiffer than shown! (No jokes please!)

Isolate the movement

I’m really interested to give the RedShift a go, merely to see if it is as effective at reducing the road buzz, as the IsoSpeed has been, yet similarly without negatively affecting racing hard on the bike.

RedShift have a few graphics on the Kickstarter claiming the ShockStop will reduce shocks by up to 70%. Which is a very interesting claim, particularly as “whats is a standard stem”? Unfortunately this is going to be a VERY difficult claim to investigate in the real world

Good line, but what is a “standard stem”

One thing I’m more inclined to believe is their blanket “significantly reduces buzz”. Again significantly is a scientifically relevant word, but would be very hard to test in the real world. However given that people spend a lot of money on carbon stems, for lightness, but also to reduce road buzz, I’m inclined to be less skeptical of this claim

Reduced the buzz

Ultimately its cheaper than a carbon stem, so I’ve plunked down to see if it does reduce any road noise, and see if my Scott is a little less violent!

RedShift ShockStop is available today at KickStarter.com – available at $99, compared to a estimated RRP of $139. Take a look if you are interested, its going to be well into 2016 before you see a review though!
