For 2012, Cervelo has compiled its innovative knowledge in an excellent frame called R5CA. The R5CA is the product of the new production techniques, test methods, and lay-ups developed by Cervelo, which means that this frameset is a technical breakthrough with many things to offer, like its rotor crankset.

Very light weight, the Rotor 3D30 is a thoroughbred performance aluminum crank. For riders who want to tackle bad roads and long rides with much ease, this is the ideal frameset as it offers much comfort from its vibration damping and vertical compliance.

Climbing is made easier by the low weight of the 2012 Cervelo R5CA Road Frameset with a Rotor Crankset. Torsional stiffness allows the riders to descend with confidence and safety while BB stiffness helps them conserve energy. Also, its tube is made light, stiff, strong by its Squoval design.

2011 eecranks set   2011 eeCranks Set

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.
