SRM Launches Power Crank With Replaceable Batteries

The "power meter" wars are on ! And, everyone, to include a well-known Japanese electronics giant, is looking for a piece of the action. But, let’s to forget about the trailblazers like SRM who ventured out into the arena of performance power cranks long before anyone else. And, still continue to set the standard for others to follow.

However, there was always one niggle about the SRM power cranks that always proved bothersome to users, and that had to do with the fact that the crank had to be sent back to the manufacturer for a battery replacement. Well, SRM lovers the world over can rejoice now that SRM has announced it’s new UCB (User Changeable Battery) design. 

Designed in collaboration with FSA, the new K-Force Light based BB386 EVO crankset uses just plain old batteries now. That’s right ! Instead of coin cells or square batteries that were once located inside the power meter, the new UCB crank uses two standard AA batteries which are stored inside the crank’s spindle. According the SRM, after about 4000 hours of use, the batteries can be replaced by simply removing them from spindle. In addition, FSA’s one-crank-fits-all BB386 spindle and cup design will accommodate all applications involving BB386, BB30, PF30, BBRight, and standard threaded bottom brackets with their threaded MegaEVO cups.

The suggested msrp for the new crank is $2845.00. While that’s by no means inexpensive, it’s still in keeping with most of SRM’s previous pricing. The new crank is currently available in a 110 compact BCD, with a 130mm BCD planned for the near future.
