SRAM's Dub cranks can become so stuck that even long levers are of little help; even brute force, a heat gun, or other workarounds don't work. This is exactly where Ceramicspeed’s new Crank Bolt Removal Tool comes in. 

The Crank Bolt Removal Tool relies not on brute force, but on mechanics. A threaded rod rests against the pedal axle, while a lever with an Allen key is inserted into the crank bolt. Turning the handwheel causes the system to build up pressure in a controlled manner and increase torque evenly—until the seized bolt loosens. This eliminates the need for extension tubes, hammer blows, or other makeshift solutions.

This clever method reduces the effort required, protects tools and components—and minimizes the risk of injury. For anyone who regularly works on Dub cranks, this special tool should be a much less stressful alternative to the previous feat of strength. Or SRAM could design the cranks so that they’re easier to disassemble.
