ShockStop: The Shock-Absorbing Bike Stem

$88,226

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 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.

The patent-pending 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.

We offer a variety of different lengths and angles with adjustable stiffness so that everyone from performance cyclists to recreational riders and commuters can find the perfect fit.

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.

In testing, the ShockStop reduced peak forces transmitted to the hands by up to 70% when compared to a standard stem. And road buzz? Forget about it. The ShockStop eats it right up.

Unwanted vertical movement is absorbed by the elastomers, but lateral motion (i.e. steering input) is directly transmitted into the fork, so your bike feels just as responsive as the day you bought it. 

Each stem comes with a number of different stiffness elastomers that can be swapped out, letting you tune the ShockStop's road-feel to match your riding style.

The ShockStop uses the same sealed cartridge bearings that are used in high-end mountain bike suspension pivots, and the forged aluminum components are extremely torsionally rigid, so climbing and sprinting feel completely natural. The travel is also specifically limited to 1-2 centimeters (6°) - enough to provide amazing cushioning against most road impacts, without affecting the geometry or handling of your bike.

So what does it feel like? In a word: smooth. Road buzz is almost completely eliminated and impacts from larger bumps and cracks are dramatically muted.

Twin interchangeable elastomers let each rider fine-tune the road feel to perfectly match their own riding style. Racers, triathletes, and competitive riders can choose firmer settings to retain a more traditional front-end feel, while commuters, fitness enthusiasts, and endurance riders can dial in a softer feel to maximize comfort.

Yes! The ShockStop will fit virtually all road, hybrid, and triathlon bikes. If your bike has a threadless stem (similar the the picture on the left), then it's an easy swap. If you're bike has a quill stem (like the picture on the right), it's still easy, but you will also need a separate quill stem adapter (commonly available for $10-$15 USD).

Installing the ShockStop is simple - you'll need a couple of standard hex wrenches (these are part of every bike multitool) and a few minutes.

On the handlebar side, the stem clamps to 31.8mm handlebars and includes shims for 25.4mm and 26.0mm bars. This covers pretty much all road, hybrid, and commuter bikes.

The ShockStop also comes in a variety of lengths and angles with adjustable elastomers so everyone will be able to find a perfect fit.

Two years ago, we started Redshift Sports to combine our passion for cycling, mechanical engineering, and product development. We launched our first product line, the Switch Aero System, right here on Kickstarter, and the response we received from the community was amazing! Our backers' support let us turn an idea into a sustainable company, and today, thousands of riders all over the world have Redshift components on their bikes. 

As mechanical engineers, we love designing innovative, elegant solutions to solve real problems. Our extensive product development and manufacturing experience let us build Redshift on a foundation of delivering the highest quality products. We have excellent relationships with key suppliers and manufacturers, and we've developed a solid production and fulfillment infrastructure. And the best part about our job? We get to ride our bikes whenever we want ... all in the name of research and development.

THANK YOU FOR YOUR SUPPORT!

Thank you so much for backing us, sharing our project with your friends, or just rooting us on!  If you have a question, check out the FAQ and if you don't find the answer there (or if you just want to provide feedback) please post a comment or contact us.  We'd love to hear from you!

Risks and challenges

Since our first Kickstarter campaign in 2013, we've built Redshift on a foundation of delivering the highest quality products. We've stayed closely connected with our original backers and continue to get amazing and positive feedback from them.

Our previous Kickstarter experience, as well as our product development background and bike industry experience, mean we have strong existing relationships with key suppliers and manufacturers. We have a realistic production and fulfillment schedule that we are confident we can achieve.

Our main priorities are to ensure that the production ShockStop is the highest quality, safest product possible, and that it reaches our backers hands as soon as possible. To that end, we have taken steps to ensure that potential risks are managed properly.

QUALITY

We have worked hard to design a great product and want to make sure that all of our production parts are of the highest quality. We carefully selected our manufacturing partners based on their proven track record with cycling products.

SCHEDULE

Over the years, we have taken numerous products (including our 1st Kickstarter project) through the manufacturing process, so we know how long each part of the process actually takes. Our experiences have also taught us how best to manage the efforts to minimize delays. We are in close contact with our manufacturing partners regarding their schedule to ensure that our timeline is appropriate.

MANUFACTURABILITY

All prototypes are not created equal – many are made using techniques that would be impossible to use in manufacturing. Our final prototypes were designed for manufacturing from the start. In addition, sometimes prototypes just look like they work - all our prototypes are fully functional and ready to be turned into production parts.
