O,Symetric chain rings make the news on Cyclingnews.com
O,Symetric chain rings are featured in Cyclingnews Sept 22 new arrivals. A more detailed review of the rings by them is expected in the following weeks.
«O,Symetric non-round chainrings have graced the bicycles of such
prominent ProTour contenders as Bobby Julich (Team CSC), Alexander
Vinokourov, and Andrey Kashechkin (Astana). While they certainly
look unconventional, O,Symetric says that altering the effective
gear ratio throughout the pedal stroke in relation to the rider’s
muscular force results in a 5-15% improvement in efficiency with
a concurrent 3% increase in speed. O.Symetric offers road rings
to fit standard and compact cranksets as well as mountain bike rings
in the current 104/64mm four-arm bolt circle diameter and older
standard and compact five-arm patterns. Our 52/42T road samples
weigh 100g and 58g, respectively, and carry a suggested retail price
of US$245 for the pair.»
