http://www.lynskeyperformance.com Let us take 3 minutes and try to blow thru a comparison between the M230 - tried and true hard core hard tail 26er - and the Pro26 - this year's new race ready, helix tubeset /BB30 equipped cross country monster machine. This is not meant to be an all inclusive, full detailed walk around, more a quick shot hopefully answering the most FAQ's!! Thanks for looking. Now get out there and ride.
