To be released this 2011 is the redesigned eeCranks set from eeCycleworks. Little was changed in terms of aesthetics adding a black option to the silver one. For a standard English BB, the whole set, which includes the bottom bracket, cranks, spider and rings, it weighs approximately 630g to 650g.
A 170mm outer BCD will be utilized by the eeCranks along with inner bolt circle diameters for both standard and compact. With the larger outer BCD, the result will be 48T to 53T+ chainrings to most compact and regular sizes and the options for crankarm are 170, 172.5 and 175mm.
While the 2011 eeCranks Set has an incredibly light weight, its performance is not reduced as one might suppose. This crankset is one of the stiffest ones on the market, if not the stiffest. Also, still being worked on is a BB30/PFBB30 crankarm/spindle design.
