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

I purchased this in May 2017, and it has been a constant fixture on both of my gravel/all-road bikes since then (initially a 2015 GT Grade Carbon and for the last year an Ibis Hakka MX). Both bikes and stem have seen substantial hard usage off-road on some of the roughest tracks you might imagine (The photo is from an Exmoor crossing, Google "riding ridgeway foul weather" for more on another particular soggy adventure). Cons: - Weight, it's a bit heavier than a standard stem. - A bit more complicated than a standard stem and the bearings will eventually wear out (still good Feb 2019). Pros: - Very robust and well engineered - aside from oiling once, no maintenance but yet remains silent in operation with no signs of any bearing play. - No impact on bike handling or pedalling efficiency - even with slightly softer pre-load than recommended (to make things a bit easier off-road) I am unable to detect any downside. - Works - it is noticeably more comfortable. Some tracks can now be ridden at a speed that previously would have either had me in the ditch or seeing double. - Enables riding bumpy sections faster - maybe placebo but Strava times, particularly when paired with a ThudBuster LT (not so high quality), are noticeably faster. In summary On a bike, your backside and your hands are the two points of contact that aren't designed to take frequent large impacts, and both suffer when they do. Having this installed has added minimal weight and made zero impact on handling and pedalling efficiency while it has made things noticeably more comfortable. This stem was the first upgrade I made to my new Ibis. It remains the first upgrade I would make to any non-suspension bike I intended to use off-road. If you currently ride on rough tarmac or off-road on a bike with no suspension, then I can highly recommend the RedShift ShockStop as an excellent comfort enhancement.

Very impressed. As others have said, it's not a replacement for suspension forks, but it's much lighter and it really does take the edge off shocks from bad roads, gravel tracks etc, and also smooths out vibrations from stones and cobbles on my rigid frame hybrid bike. I found it gets better with use - after about 100 miles it's really 'settled in' and lost some stiffness, giving a significantly more comfortable ride then when new. Read the instructions before changing the elastomers as it's easy to damage the unit. The price is high for what it is, but I suppose the inventors need to recoup the development costs.

Technically brilliant although bit pricey but it works very well! Road surface where I cycle in Surrey UK, have, over the last few years, been getting progressively worse due to poor road maintenance. Each ride would inevitably result in hitting holes in the road or avoiding them at the last second, not just uncomfortable but dangerous. Looked at some Youtube reviews and comparisons between the Specialised Future Shock and the Redshift Stem suspension. Didn't want to buy a new bike so I went ahead and bought the Redshift Stem and frankly glad I did. Has made a huge difference, gives both comfort and confidence on the roads. Means I don't have to steer out of the way of every bump in the road apart from the larger potholes. Brilliant product!

Review after daily use for 4 months. I use my bike as a daily commuter in London as well as for road trips. My bike is a gravel bike with full Shimano 105 2019 group set and a very stiff frame. I run my tyres at 55psi so the bike isn’t too uncomfortable, however potholes and speed bumps, of which there are many on my commute, make for sore arms after a long ride. The shockstop stem isn’t not cheap, around three times the price of a quality standard stem but in my opinion it’s worth every penny. Fitting was relatively easy and the suggested elastomers for my weight are spot on. The transformation was noticeable immediately and the front of the bike absorbs abrupt jolts such as drain covers and potholes smoothly. I definitely feel less discomfort after a long ride. There was no noticeable change in the acceleration or cornering which was good as I’d feared it may have degraded it somewhat, especially with the extra weight. However as I have a gravel bike with wider tyres it may be a different experience when fitting to a very lightweight fast road bike. Overall I’m pleased with my purchase and can recommend buying.

Ich hatte vorher schon eine Redshift Shockstop Sattelstütze verbaut (auch SEHR zufrieden damit) und wollte am neuen Gravelracer ein wenig Komfort für die Handgelenke. Was soll ich sagen, ich bin 100% zufrieden mit der Entscheidung. 1. Habe ich im Vergleich zum Serienteil 10 mm kürzer gewählt, jetzt sitze ich besser auf dem Rad und auch das Lenkverhalten ist etwas zackiger. Die Federung beeinträchtigt das Lenkverhalten dabei kein bisschen. 2. Das Wesentliche ist aber, daß der Vorbau den Schotter fast komplett wegbügelt (in Bremshebelposition) ! Wurzeln, Kanten und Schlaglöchern wird der Schrecken genommen, unten "zappelt" das Rad und auf den Hoods herrscht fast Stille. In der Unterlenkerposition ist der Effekt etwas schwächer ausgeprägt, aber immer noch deutlich vorhanden. 3. Wiegetritt ist kein Problem, der Vorbau "geht" nur in die Richtung, die er soll, und auch unter Belastung funktioniert die Federung weiter. Top. Natürlich ersetzt der Vorbau keine gut eingestellte 80mm+ Federgabel, aber WAS er leistet, ist echt enorm. Elastomer-typisch spricht die Federung bei kleinsten Stößen bereits an, und genau das macht die Fahrten mit dem Redshift so entspannend. Das wenige an Zusatzgewicht, was die Stütze und der Vorbau mitbringen (zusammen ca. 500 Gramm verglichen mit regulären Aluteilen) machen sie meiner Meinung nach dadurch um ein Vielfaches wett. Die Montage war in der Beschreibung vorbildlich erklärt, die Auswahl der Elastomere passte auch (ich, 75kg, habe 50/70 eingebaut bei 90mm Vorbau und -6° Einbauposition, die 40/70 Kombi, die ich wegen des kurzen Vorbaus angedacht hatte, war mir zu weich). Die Verarbeitung ist vorbildlich. Abweichend vom Produktbild bekommt man schönere (finde ich) Klemmschrauben. Alles in allem bin ich richtig glücklich mit dem Teil und empfehle es jedem, der auch nur gelegentlich seinen Renner/Cyclocrosser/Randonneur oder Gravelracer über auch nur moderat schlechten Belag steuern möchte. Ein echter Peacemaker für die Handgelenke!

The Shockstop stem has all the benefits of suspension with none of the drawbacks. I was concerned that it would be too heavy, would not absorb enough shock or would negatively impact the ride. The ShockStop is brilliant. On my flatbar road bike it works exactly as advertised. It is a very stiff bike with narrow wheels and I felt every bump. The 10mm of travel completely absorbs most bumps and saves so much pain and numbness in my hands. I’ve changed from cautiously avoiding bumps to actually aiming for them! The stem does add a small amount of weight but I absolutely did not notice it. My concern that it might effect performance or ride negatively was also unfounded. I previously had significant pain in my arms when riding but the ShockStop stem has removed it. It’s made it feel like a completely new bike and I could not be happier.

ロードバイクで使用。初め、ろくに説明書も読まずに装着したところ、全くサスペンションが効かないので、説明書を熟読。 このステムには上下があり、+6°または-6°を選択可能とのことだが、そのままひっくり返すだけではダメで、ステム内の部品をを上下逆にする必要がある。厳密には+6°または-3°。製品の精度かもしれない。 使用感は素晴らしい。軽トラからレクサスに乗り換えたような感覚。 乗り初めはやや違和感があるものの5分で慣れる。 通常のライディングポジションでやや沈み込むので、ハンドルをやや上向きにセッティングした方が良い。 上り坂は通常より疲れる印象。ヒルクライムには向かない。 ロードバイクで使用する場合、もう一段階固くした方が快適度が増すかもしれない。 サスペンションが樹脂なので、使用時期によっても硬さを変えた方が良いかもしれない。 色々と試せるのも魅力。 取り付け器具があり、プラスチック製品なのだが、注意して締めた方が良い。当方は締めすぎて破損してしまった。 あらゆるパーツの中で最も乗り味が変わると思われる名品。 本格的なレースには不向きだが、快適な通勤やポタリングを望む方には是非おすすめしたい。

After reading some of the negative reviews and comments I wasn't sure what to expect. This is definitely working for me on my new Cannondale Topstone gravel bike. My commute to work is 8 miles (one way) and the bike path and roads are not even. Especially roots pushing up the pavement is common on the bike path. It is rather painful when going 20mph and hitting them unexpectedly (e.g., in the dark). I am also going on an unpaved trail through the woods. The before and after are astonishing to the point that I am still impressed even after riding this for a couple days now. The movement of the handlebar is substantial. I didn't expect that. The quality and craftsmanship of the stem are excellent. The installation was easy (unless you are as stupid as I am and remove the original stem with the magnetic brackets falling down to the bottom of the fork inside the carbon fiber tube - duh). Overall, a much smoother experience now and a lot less impact on my hands and arms. So much more fun! One little side effect that is somewhat annoying is that my rearview mirror is shaking quite a bit due to the dampening effect :). I followed the weight table, and it seems to be just right. I wouldn't want it any softer or harder at the moment. Once the weather gets better, I'll try out a mountain bike trail with it. I am very impressed

Ho aspettato molto prima di montare sulla mia bici gravel questo strumento che attenua le scosse sul manubrio che mi aveva consigliato un amico perchè mi sembrava eevato il costo. Devo dire che mi pento solamente di non averlo fatto prima, cambia completamente la comodità, ma anche la sicureza in quei tratti dove ci sono molte scosse a causa delle asperità del terreno. Il costo vale tutto assolutamente consigliato. Prenderò anche quello per il sellino tra non molto.
