Dual Edge Block - 28RXE
Dual Edge Block - 28RXE
A 28mm rolling edge for full-pad FDP work. The roll biases load toward your deep flexors with zero skin drag, which a fixed edge cannot.

Take the next step in your finger strength and finger health journey with this compact, FDP‑focused rolling edge. A completely different experience than traditional fixed edges, the smooth rolling surface minimizes skin drag while maximizing muscle activation. Designed to work across a wide range of hand sizes, it’s ready to use at the gym, at the crag, or at home.
- Universal fit: One tool for both hands with an extensible roller system.
- Efficient strength building: Targets the deep finger flexors within a controlled, strength‑focused protocol.
- Low‑friction design: Helps protect skin and tendons while keeping the emphasis on engagement.
- Controlled stimulus: Small‑edge grip training that stimulates and supports a 3/4 edge position.
Perfect for targeted FDP‑biased work and for exploring more advanced high‑angle crimp positions in a structured way. If you’ve heard climbers like Aidan Roberts, Hamish McArthur, or Daniel Woods discuss high‑angle crimping, this tool lets you practice similar grip positions with deliberate loading and progression.
Includes the platform grip base, one (1) straight 28mm roller, one (1) variable‑radius unlevel roller, and tools to interchange the grips. The unlevel roller is the most popular choice and comes pre-installed.
Choice of cord color. Carabiner not included.
NO
FRICTION
The edge rolls. Your fingers do the work.
Smooth ball bearings take skin drag out of the hang. What is left is the FDP, the deep flexor that closes a crimp. A light texture says where to grip without letting skin carry the load.

General
Think of this as a small, high‑quality finger session you plug into your existing programming, rather than something you do randomly. It is complementary what you do now and isn't meant to replace any current training.
We feel most can gain benefit from the 28RXE while we only recommend the 22RXE Micro Elite to those who have long standing training and are comfortable or have used edges around 10-15mm.
A few factors play into why it feels "harder" or you end up using less weight. Friction plays a huge role in hanging on holds, edge and most everything else in the world. Thats why we have fingerprints.
The RXE is designed to remove friction and focus on engagement and form. We have all have seen poor form of fingers hanging on for dear life only using friction and connective tissue to lift an edge.
This tool won't allow that.
There are some core differences between all 2 sized platforms.
- 28RXE is perfect for most people as its a near full pad comfortable edge platform and is good introduction into FDP training with its solid roller design and swappable rollers. We suggest this as a starting point.
- 22RXE Micro is a much smaller edge than the 28RXE and can be a benefit to those who need higher stimulus to the FDP. The roller will lie on about 1/2 to half of a pad. When you use the block it might feel like a 10mm edge in terms of skin pressure.
The goal for form is to make sure your DIPs are engaged on the roller surface and your middle phalanx at 90 degrees to the platform backface.
It is helpful to think of sort of gripping your finger tips in a talon grip position.
Avoid hyper extending to get behind the roller surface. Form is everything and a little goes a long way.
- Ensure a good warmup
- Start with standard edge no hangs or hang boarding, then proceed to RXE training
- A common pattern is using 10 or 20 second holds keeping the weight much lower than your usual training weight.
- Integrate into structured finger training with timed isometric holds.
- We suggest avoiding 1RM or near max training as the failure mode (rolling off the fingers) is not controllable.
In order to find a good starting weight, we suggest using 1/2 the normal weight you would use on a standard edge.
22RXE use 1/2 of what you normally use on a 10mm edge while hanging or lifting and 28RXE use 1/2 of what you normally do on a 20mm edge.
A rolling edge feels very different from traditional finger boarding and different than normal climbing. Expect even more isolated loading of specific finger flexors. Not a replacement but, a complementary tool.
- The intense fingertip pressure is expected on the Micro during power sessions the effective "feel" of this edge is similar to 10mm holds.
- With sensible progression and no clear technique error, user will typically adapt as skin and tissues condition to the new loading.
- You would experience the same thing if started hanging on micro edges without exposure.
- We recommend reducing weight to a place where you can comfortable hold for 20s and progress from there.
