Good things come to those who wait. With our OSPW X for SRAM’s Eagle Transmission group that’s no exception. Building off a cutting-edge and acclaimed foundation has kept us on our toes, but we firmly believe we’ve been able to develop something that elevates SRAM’s innovative group. In true CeramicSpeed fashion making something already good even better.

Introduced here for the first time with our FURTHER DRIVE Technology – a preliminary culmination of our commitment to combining efficiency and durability. It consists of two new tech features -Active Debris Remover (ADR) and the ALPHA Disc – that are both aimed at making the new OSPW X boost the Transmission group’s ability to perform efficiently over time.

For our new OSPW X, the FURTHER DRIVE Technology is combined with an entirely new cage structure utilizing more material mass – without adding unnecessary bulk – that makes it perfectly in line with the robustness that the Eagle Transmission group is celebrated for. But the true value is found in the FURTHER DRIVE Technology’s ability to provide peak performance deep in races or late in the season when riders need it the most.

Faster now, faster down the line – Cover More Ground

Active Debris Remover (ADR)

ADR is a patent-pending technical feature that is based on a unique combination that makes it virtually impossible for debris to enter the bearing.

It consists of a new dust cover design that sits safely anchored in a groove in the pulley wheel, thereby completely enclosing the bearing. This is paired with a bladed groove structure that surrounds the dust cover, which dynamically extracts debris from the pulley wheel when it’s rotating.

ADR has been developed in a constant pendulum between our R&D department, the CeramicSpeed test lab, and field testing conducted by a select group of our professional off-road teams.

ADR was tested to its limits during this year’s Cape Epic, where our XCM team Buff/Megamo was riding prototype versions of a solid pulley wheel featuring ADR. During what proved to be the worst conditions experienced at Cape in recent times, the ADR feature stood its ground and kept all mud, water, and debris from entering the bearing.

ALPHA Disc

On our new OSPW X for Transmission, we’re introducing a 20-tooth solid disc pulley wheel, simply known as the ALPHA.

The ALPHA Disc features a two-piece construction. A separate narrow-wide tooth profile produced in a composite material that offers prolonged wear protection and noise reduction. As well as a solid aluminum disc that eliminates the potential of external objects getting stuck between the spokes of the pulley wheel, while adding strength and stiffness to the Pulley Wheel design.

The first iterations of our solid disc pulley wheel design were tested in the field during CycloCross World Cups a couple of years ago. During the 2022 CycloCross season, our sponsored team Tormans used the solid disc design extensively and provided valuable feedback on its ability to provide mud clearance in the worst of conditions.

 

Development Story 

Get an exclusive look into the heart of CeramicSpeed when Morten Andersen, Technical Engineer – and Lead Engineer on the OSPW for Eagle Transmission – and Mike Garrigan present the foundational work that went into the OSPW X for Eagle Transmission and how it’s newly added patent-pending technologies were brought to life.

Development was not a straight-forward process and relied heavily on both crucial feedback from our sponsored teams and test validation from our own Test Lab:

Testimonials

MTB Marathon Team Buff/Magamo and Belgian World cup Cyclocross team Tormanns have had a important role bringing valuable knowledge from the field – and made it possible for us to stress test the ADR technology and Alpha Disc under in some the toughest real world conditions.

This being an integral part of the development of our OSPW for Eagle Transmission.

Hans Becking

“At this year’s Cape Epic, we had crazy weather, lot of rain. After so many brutal race days, I was really surprised how good the Alpha Disc works. I see so many issues in the peloton, but it is super reliable. It’s a gamechanger for me.”

Guillem Alba

Mechanic on Buff/Magamo

”We had the ALPHA Disc one month before the start of this year’s Cape Epic. We used them at Cape Epic – and stayed on them after because they worked perfectly. For the last six months, I have only done maintenance on them once – and they work perfectly.”

Head Mechanic Tormans Cyclo Cross Team

“To optimize the current version of the OSPW, we started to think of solutions to let it perform even better in heavy mud. We gave feedback to the CeramicSpeed R&D Department – asked them to work on a full disc design to avoid mud sticking to the pulley wheels, to perform better in heavier conditions.

We used the first version of the full pulleys for 1 season, then we got an updated pulley wheel with a bigger bearing and caps with the “ADR function” to avoid grass and mud turning in the bearing and mud sticking to the pulley wheel.

Till now we are still using these same prototype pulleys in the heaviest circumstances and “grass races”, because it makes a huge difference for our riders to ride their bikes without a hopping gear or bad-turning drivetrain.”
