Redshift ShockStop Stem Review: First Impressions

Unboxing The ShockStop Stem

When the Redshift ShockStop Stem arrived, the packaging was neat and tidy. Inside the box, we found the stem itself, a set of color-coded elastomer inserts, and a clear instruction manual. A sticker warns about the access hole to the internals, emphasizing the importance of following the setup guide. It’s clear from the start that careful installation is key.

Initial Setup And Elastomer Selection

Setting up the ShockStop Stem involves selecting the correct elastomer based on rider weight. Redshift provides a range of elastomers to cater to different riders, from lighter individuals to heavier ones. We found the elastomer selection process straightforward, guided by the included manual. It’s important to get this right for optimal performance and to avoid any issues. We recommend checking out installation videos online to supplement the manual, especially if you’re new to bike maintenance. Getting the elastomer setup correct is vital for the stem’s function, and we found it to be a pretty simple process.

Compatibility With Handlebar Styles

The ShockStop Stem is designed to work with standard 1-1/8″ A-HEAD steerer tubes and is compatible with both drop bars and straight handlebars. It’s primarily intended for 31.8mm handlebars, but shims are available for smaller diameters like 25.4mm. This broad compatibility means it should fit most modern bikes, including many e-bikes. We appreciate that Redshift considered different handlebar setups, making this a versatile option for many cyclists looking to add comfort to their ride. If you’re curious about how it might fit your specific bike, checking out the Redshift website is a good first step.

Performance On The Trail: A Real-World Test

We took the Redshift ShockStop Stem out for a good long ride to see how it handles real-world conditions. Our testing focused on how it deals with the kind of bumps and vibrations that can make an e-bike ride uncomfortable, especially over longer distances.

Dampening Rough Roads And Vibrations

On pavement that’s seen better days, the ShockStop Stem really shines. It noticeably smooths out the constant buzz from cracked asphalt and uneven surfaces. We found that it significantly reduces the fatigue in our arms and hands, which is a big deal on longer rides. It feels like the road is less

Comparing The ShockStop Stem To Alternatives

When we look at ways to smooth out our rides, especially on e-bikes where comfort can mean longer adventures, the Redshift ShockStop Stem isn’t the only game in town. We’ve spent time with various setups, and it’s worth seeing how it stacks up.

ShockStop Stem Versus Suspension Forks

Suspension forks are the traditional go-to for front-end comfort. They offer significant travel and are designed to absorb big hits. However, they add weight and complexity. The ShockStop Stem, on the other hand, is a much simpler, lighter solution. It focuses on damping smaller vibrations and impacts, rather than soaking up massive drops. For many e-bike riders, especially those on paved or light gravel paths, the stem provides enough relief without the added bulk and maintenance of a full suspension fork. It’s a trade-off between targeted vibration reduction and all-out bump absorption. We found that while a suspension fork handles a pothole better, the ShockStop Stem makes rougher roads feel much less jarring over time.

ShockStop Stem Versus Other Stems

Most stems are rigid metal tubes. That’s it. They connect your handlebars to your fork’s steerer tube. The ShockStop’s unique selling point is its internal elastomer system, which allows for a degree of movement. This movement is what dampens vibrations. Compared to a standard stem, the difference is night and day on anything but perfectly smooth pavement. Some other aftermarket stems might offer different angles or materials for weight savings or aesthetics, but few, if any, incorporate suspension like the ShockStop. We did notice that some stems might offer a slightly stiffer feel, which some riders prefer for precise steering, but at the cost of comfort.

ShockStop Stem Versus Suspension Seatposts

This is where things get interesting, as Redshift also makes a well-regarded suspension seatpost. While both aim to improve ride comfort, they do so in different areas. The seatpost handles impacts that travel up through the rear wheel and into the saddle. The stem deals with impacts coming through the front wheel and handlebars. We’ve found that using both the ShockStop Stem and a suspension seatpost can create a remarkably smooth ride, almost like floating. However, if you have to choose one, consider where you feel the most discomfort. For us, the stem made a noticeable difference in hand and arm fatigue on longer rides over chip-seal roads. If you’re looking for a way to add comfort without altering your bike’s core geometry too much, the ShockStop Stem is a strong contender.

Design, Materials, And Construction

Engineering and Materials Used

The Redshift ShockStop Stem feels solid from the moment you unbox it. We’ve found the main body is constructed from 7075 aluminum, a material known for its strength and relatively light weight. Redshift employs a 3D cold forging process for this part, which generally results in a stronger, more durable component than standard machining. The fasteners are also a good grade of stainless steel, which should resist corrosion well. It’s clear that Redshift Sports, being mechanical engineers, put a lot of thought into the build quality. They even fatigue test their components to higher loads than industry standards, aiming for long-term reliability.

Available Sizes and Configurations

We tested the 6-degree version, which is a good all-around choice for many road and gravel bikes. However, Redshift also offers a 30-degree option, which might be better suited for hybrid or more upright touring setups. The stem is primarily designed for 1-1/8″ A-HEAD steerer tubes, but adapters are available for other sizes. For handlebars, it’s built for the common 31.8mm clamp diameter, with shims available for smaller bar sizes. Length options for the 6-degree model include 80, 90, 100, 110, and 120mm, giving us a decent range to dial in fit. The 30-degree version only comes in a 100mm length.

The ShockStop Stem Pro Option

While we focused on the standard ShockStop, it’s worth noting that a Pro version exists. The Pro model offers a wider range of adjustment and potentially a slightly different feel, though the core design and materials are similar. For those seeking the absolute finest tuning or perhaps a specific aesthetic, the Pro might be worth investigating, but the standard version is already a very capable piece of kit. It’s interesting to see how companies like Redshift are adapting their designs, much like how e-bike manufacturers offer different battery options, such as the choice between 36-volt and 48-volt batteries depending on rider needs.

Maintenance And Durability

We’ve put a good number of miles on the Redshift ShockStop Stem now, and it’s held up well. Redshift Sports, being mechanical engineers, really focuses on making sure their gear can handle a lot. They test their products way beyond standard requirements, which gives us confidence in its long-term use.

Routine Checks And Tightening

After the first few rides, especially after hitting some rougher roads, we noticed the stem bolts needed a slight snugging up. This is pretty normal for any new component, really. We found that giving everything a quick check every 50 miles or so, especially after a wash, is a good habit.

• Check stem faceplate bolts.
• Ensure the main pivot bolt is secure.
• Inspect elastomers for any signs of wear or damage.

We haven’t had to do much beyond that, which is a good sign.

Elastomer Longevity And Replacement

The elastomers are the heart of the suspension system, and their lifespan depends on how much you ride and the terrain you cover. We haven’t had to replace any yet, but Redshift provides different elastomers for various rider weights and preferences. If you ride a lot on rough surfaces, you might wear them out faster. Replacement seems straightforward, involving removing the faceplate and swapping them out. It’s a good idea to keep a spare set handy if you do a lot of off-road riding. You can find replacement elastomers on the Redshift Sports website.

Long-Term Durability Observations

So far, the stem’s finish has stayed looking good, with no signs of corrosion on the fasteners, which are a decent grade of stainless steel. Barring any major crashes or improper installation, we don’t foresee any significant issues. The design is pretty robust, and it feels solid even after extended use. It’s a well-made piece of kit that seems built to last, offering a noticeable improvement in ride comfort without adding much weight or complexity.

Who Is The Redshift ShockStop Stem For?

We’ve spent a good amount of time with the Redshift ShockStop Stem, and it’s clear this isn’t for everyone, but for a specific type of rider, it’s a game-changer. If you’re looking to add some comfort to a bike with a rigid fork, especially an e-bike, this is definitely worth considering.

Ideal Rider Profiles

We found the ShockStop Stem to be particularly beneficial for riders who prioritize comfort on longer rides or those who frequently encounter less-than-perfect road surfaces. It’s great for:

• Commuters dealing with rough city streets.
• Gravel and adventure cyclists looking to smooth out washboard roads.
• Road cyclists who want to reduce hand and arm fatigue on longer outings.
• Anyone with a bike that has a rigid fork and wants to improve ride quality without a full suspension setup.

Ultimately, if you’re feeling the sting of every crack and bump, this stem is designed to help.

E-Bike Applications

On e-bikes, the ShockStop Stem can be especially effective. Many e-bikes, particularly those with smaller wheels like some 20-inch models, can feel quite jarring on rough surfaces. The stem helps absorb those impacts, making the ride more pleasant. We tested it on a bike with a rigid fork, and the difference was noticeable, particularly when hitting smaller obstacles or uneven pavement. It’s a good way to add comfort without the added weight and complexity of a suspension fork, which can be a significant factor on an already heavier e-bike. For those exploring urban environments or light trails on their e-bikes, it’s a solid addition. You can find some great examples of e-bikes that could benefit from this kind of upgrade, like those with 20-inch wheels.

Limitations and Considerations

It’s important to be realistic about what the ShockStop Stem can do. It’s not a replacement for a full suspension system. While it smooths out vibrations and smaller impacts, it won’t provide the same level of control or comfort on truly rough off-road terrain as a suspension fork would. We also noted that it’s not compatible with all handlebar styles; specifically, swept-back or cruiser bars can interfere with its intended function. Setup also requires a bit of attention to detail to get the elastomer selection just right for your weight and riding style. If you’re planning on aggressive off-road riding, you might be better served by a different solution, but for general comfort and vibration reduction, it’s a strong contender. Remember, it’s designed to smooth out road imperfections, thereby reducing rider fatigue.

Frequently Asked Questions

What exactly does the Redshift ShockStop Stem do?

Think of it like a little shock absorber for your handlebars. We’ve found it really smooths out the bumps and shakes you feel when riding on rough roads or trails. It uses special rubber pieces, called elastomers, to soak up the jolts, making your ride much more comfortable and less tiring.

Does it work with any type of handlebar?

It’s designed to work great with most common handlebar styles, like the straight ones on many e-bikes and the drop bars found on road bikes. However, it’s not a good match for handlebars that sweep way back, like those on some cruiser bikes, because the way they’re shaped can mess with how the stem’s suspension works.

How does it compare to a full suspension bike?

While it won’t give you the same kind of big travel as a full suspension bike, especially for off-road riding where you need maximum grip, it’s a fantastic way to add comfort to bikes that don’t have front suspension. It’s much lighter and simpler than adding a suspension fork, and it does a really good job of taking the sting out of smaller bumps and vibrations.

Is it difficult to set up or maintain?

Setting it up is pretty straightforward, especially if you follow the instructions closely. You can even swap out the rubber elastomers to fine-tune how much cushioning you get based on your weight and how you like to ride. We haven’t had to do much maintenance beyond making sure the bolts are snug now and then, and the elastomers seem to last a good long time.

Who would benefit most from this stem?

We think this stem is awesome for anyone who rides on less-than-perfect roads, whether that’s gravel paths, bumpy city streets, or just aging asphalt. It’s especially good for e-bike riders who might be covering longer distances or want to reduce fatigue. If you’re looking to make your current bike feel smoother without a major overhaul, this is a great option.

Are there different versions of the ShockStop Stem?

Yes, there is! Besides the standard version, Redshift also offers a ‘Pro’ model. This version uses even better materials and some clever engineering to make it lighter. It’s a bit of a premium upgrade if you’re really focused on shedding every possible gram from your bike.
