Title: dr pulley sliding roller weight
Post by: x9 rider on October 01, 2009, 04:21:54
recently i've purchased 11 g dr pulley sliding rollers for my x9 180 amalfi. low & mid range torque had improved drastically . for da info , my stock round rollers are 10.7g   . however found out later that the conversion from round rollers to sliding rollers should not be 1:1 but should less between 10 - 15 %. in other word i should go for 10g instead of 11g. the question is , will my top end decrease if i opt for 10g sliding rollers which is lighter than stock ?

Shouldn't make any difference. Dr Pulleys give a higher ratio at full lift anyway than normal rollers.
