Cyclist Bikers question

[DaShen]

Anyone heard of the new Carbon SRAM Force Grupo?
Has anyone used it?

**EDIT**
How about Power Cranks?

 

[DaShen]

Anyone?

The SRAM Force looks interesting but expensive, but Power Cranks sound like a lot of fun and good for training. What do you think?

**EDIT**
BTW for anyone that doesn't know. 'Power Cranks' are cranks that have free rotational axis for both side. Meaning you can pedal with only one side if you want while having your other foot remain stationary. It is supposed to strengthen your legs and also take away any problems in your pedal stroke.
