I have an older Kona Cinder Cone Race Light bike and i am trying to identify the year and possible value of it. It has what looks like 4510 and 7515 stamped below the crank area. It has up shift and down shift paddles along with rock shox magnesium front forks. It has a Mavic rear wheel and a Zac 19 front wheel. Race light seat post and front bar. Any info would be helpful. Thanks.
