thx mate...pinknugget said:I'm running a Totem coil and thinking about switching to something in the 160-170mm range...hmmm... The longer fork makes the bike ride a little slacker, adding to the down hill stability and increasing your margin of error up front. Either way you are going to sacrifice something. If your doing mostly DH type stuff I would go with 180, otherwise try the Marz 55 for a while and see how it goes.
