Cane Creek's original Ergo Control took the bar end to an unprecedented level of performance. Its ergonomic profile, extending both fore and aft of the handlebar, gave riders more comfort and control than was previously possible. The design fit the rider's hands naturally and aligned hisher weight over the center of the steering. Now Cane Creek offers the Ergo Control IIwith even more technology that makes sense. Construction: The optimized shape offers more hand positions for improved comfort and reduced weight. The new aluminum spine clamp is engineered to be stronger and lighter. The composite skeleton provides better, more uniform support with fewer grams. The outer rubber surface with raised Cane Creek skinks and logos is softer and tackier to improve your grip. And by integrating ODIR's patented Lock On System technology, Cane Creek has introduced the first bar ends that mate with Lock On handlebar gripsincluding the Cane Creek locking grips. Of course, the Ergo II's are also compatible with traditional handlebar grips.
