Reverse Components Stems

1 Stem, 2 handlebar diameters. The Black One D-2 stem builds on the success of our flagship Black One Enduro stem and brings in the ability to run both Ø31.8mm and Ø35mm handlebars with one stem.
The special designed shim allows the use of Ø31.8mm bars and when removed, it works as an Ø35mm stem. The shim provides a wide, smooth clamping area which is ideal for use with carbon bars.

The intelligent no-gap clamping design in the bottom ensure no pinch points, and equal clamping force for safety and stability. Because the most loads and notching effects are always at the bottom of the handlebar. And our smooth no-gap surface enlarges the lifetime of your handlebars.

The Black One D-2 is ideal for riders who have a few sets of Ø31.8mm/35mm bars with different rises and want to continue using them all, or who may want to upgrade to a 35mm bar in the future, without having to buy another stem. Available in 35mm lengths in Black matt finishes.

We also offer an extra light Black One D-2 TITANIUM version of this stem with understated Black or Polished finishes, with full Titanium bolts.

To give you more guidance on your bike setup, we have developed the stem calculator.
This shows you how the reach & stack changes when you change stem length or stem angle. In addition, you will find an explanation of what the terms "reach & stack" are all about. (click here)

This fully CNC machined stem has been developed and designed for the All Mountain and Enduro use. It’s short 40 mm length making it perfect for achieving a fast handling ride. But many of our slopestyle athletes are loving the BASE!

Its stability and its short length and low height make this stem a popular dirt and slopestyle stem that you can rely on in every situation!

Yes, we still offer stems for 25.4 mm handlebars!
Most manufacturers have removed this size from their range long ago and anyone looking for a proper, stable, lightweight and nice stem is left alone!

With our Youngstar stem, we continue what we started in 2018 with the Youngstar pedal.
Child-friendly ergonomics, safe handling and low weight!

Our Youngstar stem uses our Reverse Power Cube technology for mounting on the steerer tube. The Reverse Power cube is located inside the stem and clamps both the handlebar and the steerer tube with only one set of bolts on the front of the stem.

Our specially designed clamping technology allows for a super light and easy to adjust system, which offers a high level of safety.
The technique specifically eliminates the need for bolts for the steerer clamp, allowing for a smooth, round design. This avoids harsh edges that could possibly cause injuries to the knees, arms or face in the event of a fall or slip.
As with the other products in the Youngstar series, ergonomic design, strength and safety are our top priorities.

It’s super easy to use if the handlebar is replaced, a spacer is added under the stem or routine maintenance is done. In order to reduce unnecessary weight and make the learning of riding MTB as easy as possible for the children, the stem is kept very short!
With a length of only 35 mm and a low stack height, this stem offers a compact, manoeuvrable cockpit to give children more control.

Features
- Length:  35 mm
- Clamping diameter: 31.8 mm
- Ø head tube: 1 1/8"
- Angle: 0°
- Stack height: 38 mm

Not many developments have had a similar impact on mountain bike sports as the E-Bike has. It’s opened up new people to the sport, new abilities to go further, faster!

But not only the frames, also the components have to be proven for the new requirements that E-Bikes demand. The components need to be able to take higher loads due to the frequency and duration of rides being significantly higher on an E-Bike, Your regular after work ride Trail round you did once in the pre-E-Bike-era, can be ridden three times in the same time today with support of pedal assist.

That's why the cockpits of modern E-Bikes have to take much higher loads than before. With the development of our E series stems, we responded to this development! The E-XC 6 ° stem is a real all-rounder with many different lengths to choose from to meet the individual ergonomic needs of our satisfied customers.

If you want to make the seating position more ergonomic on your e-bike and do not want to compromise on safety and quality, this cold-forged stem is the perfect choice!
The stems of the E-XC series have been tested according to the "EFBE EPAC MTB-XC Tri-Test" and can be mounted on all types of E-bikes.

Our XC stem is one of our most popular stems ever!
With its wide range of different lengths, its low weight and very high strength and stiffness, this stem offers the possibility to use it across all disciplines like no other stem in our program. Almost every conceivable ergonomic adjustment of the sitting position can be realized, regardless of whether a long or short reach is desired.

Thanks to the flip-flop system, it is also possible to mount the stem with both, a positive and a negative angle.

The Reverse Components lift adapter is specially designed for the well-known easyLOOPsystem for drag lifts, found in many bikeparks.

Our new adapter allows for improved use of the easyLOOPsystem for Downhill Bikes with Dual-Crown forks, and for single crown riders with standard stems without rear notches, for a firm mount to the system. With the adapter, it creates a super secure interface between the bike and the lift -making it easier to hold the line up the hill, with more stability and less effort to take the lift.

With Direct Mount Downhill stems, a 100% secure fit to the easyLOOPsystem lift hook can not always be guaranteed. This can lead to difficulty using the lift, or making the lift unusable for that bike. This can also be the case with standard MTB stems, that have no notch between the two steerer clamp bolts.

For this reason, we have developed the special steerer tube lift adapter to solve this problem. The adapter is mounted directly on the 1 1/8" steerer tube. For Downhill bikes, above the triple clamp, providing a firm interface for the easyLOOPsystem to hold onto.

With a standard stem, the adapter is mounted on the steerer tube above or below the stem instead of a spacer. This allows for a firm connection between the easyLOOPsystem and the stem, for a safe journey to the top of the mountain!

With Reverse's AirCon Brakepad System you will be able to install cooling fins to your brake. The fins are not attached to the pad, so that you can reuse the fins and produce less waste. Apart from the cool look it will reduce the heat in your brake caliper by up to 9 %. Now everyone can benefit from a simple brake tuning and run our AirCon Disc Pads. Another benefit is that you just need to buy the AirCon Sytem once and can replace the pads with our AirCon Replacement Pads seperately.
