ABSOLUTE BLACK Oversized derailleur cage System Hollowcage | SRAM Red/Force AXS 12-speed
With the hollow cage, the guys from Absolute Black are taking a completely new approach to oversized rear derailleur cages. The Monoplate construction is lighter and more aerodynamic than any solution previously available on the market.
Stiff roll
The popular belief is that a stiff cage equals good shifting. But if you take a close look at how the derailleur gears work, it quickly becomes apparent that the shifting precision depends largely on the upper roller. Since the upper roller is installed directly in the pivot point, the rigidity of the cage hardly plays a role in shifting precision. Rather, a stiff bearing of the roller is crucial. In contrast to other manufacturers, Absolute Black uses oversized bearings to reduce the lateral play of the wheels to a minimum and thus increase shifting performance.
Flexible cage
The design of the cage allows for some alignment of the lower roller to keep the chain running as straight as possible. In addition to the smooth running of the chain, this special feature also reduces running noise.
X ring pulley
The patent-pending Xring-Pulley uses special rubber bands to reduce the noise of the chain by 12-14dB compared to the standard Dura Ace wheels. This corresponds to a noise reduction of about 60%.
High tooth profile
Some of the competitors use rollers with a very flat tooth profile in their oversized derailleur cages. However, a tooth that is too flat will never shift the chain to another gear as precisely as a tooth that is too high can. Absolute Black uses very high teeth on the upper roller of the hollowcage for exactly this reason. In conjunction with the large and stiff bearing , this results in the best possible shifting performance.
The game with the watt saving
There are many variables that can contribute to saving a watt or two. Lightly greased full ceramic bearings are used in the hollow cage for maximum service life. Thanks to the high tooth profile, the system manages with little cage tension and still shifts extremely precisely. The aligning lower roller also saves some power because the friction in the chain run is minimized.
The cage is suitable for SRAM AXS Road 12-speed rear derailleurs.
IMPORTANT:
When travelling, please remember to dismantle the complete rear derailleur with an Allen key, as very few bicycle transport bags offer enough space for such large rear derailleur cages.
