This rear derailleur makes Sram and Shimano look really old

There's no question that the circuits from these two circuit giants work perfectly. But when it comes to repairs, both could offer significantly more spare parts. This is where Madrone Cycles steps into the breach, focusing on the so-called right to repair. Even the smallest part on the rear derailleur can be replaced.

Madrone Cycles leads the way with the Jab Derailleur: There are many spare parts available for the rear derailleur, so a complete replacement is not necessary in the event of a defect. What's more, there are clear and detailed service videos for every product, so repairs shouldn't be a puzzle. And if you don't want to do the repair yourself - provided you are within reach of the US manufacturer - you can take advantage of this service at Madrone Cycles.

The component specialist not only offers the so-called Right of Repair for its own parts, but parts are also available to get derailleurs from Shimano or Sram fit again, for example. Quite apart from the repair option, the Jab Derailleur also has a lot to offer technically. The Jab's Flex Cage technology is designed to control chain vibrations. The lower derailleur pulley offers lateral freedom of movement, while the upper one is fixed. This keeps the shifting precise, but gives the chain more room to maneuver on rough terrain. This improves chain stability without compromising shifting performance.

The compatibility is really impressive: The shifter is compatible with 9-, 10-, 11- and 12-speed drivetrains - simply by replacing the so-called Shift-Cam module. Mechanical shifters from Shimano & Sram are supported, including for road bikes.

Sram presents new generation of rear derailleurs

The first pictures made the rounds back in January 2012, and now Sram is officially raising the curtain on a new product generation for shifting on the rear wheel: With the "Type 2" gear changers, a tensioning mechanism on the cage of the X0 and X9 groupsets ensures smooth gear shifting when rodeoing downhill. When designing the new rear derailleur, Sram also thought about easy installation and removal of the rear wheel.

XTR launches a carbon rear derailleur for the first time

In the coming year, not only the new XT groupset will rely on the "Shadow" rear derailleur, but also the top XTR group. The rear derailleur with the technical designation RD-M972 also sits behind the dropout and is offset inwards by 11 to 18 millimetres, depending on the gear engaged. In this way, Shimano ensures that the derailleur is less prone to damage in the event of a fall and hits the chainstay less often.

Is my rear derailleur really crooked?

Cable tension, end stops, the angle of the rear derailleur and several other factors determine whether the derailleur on the bike works correctly or not. And if the rear derailleur cage is warped after a crash, the adjustment can become a fiddle or even be impossible. As the T-Type rear derailleur from Sram is remarkably crooked by nature, there is now a clever helper that shows whether the rear derailleur is still ok or has gone off the rails.
