The gear box bike has been kicked around for a while now.  I think that technology is getting better and the gearboxes are eventually going to take over in the gravity market.  Here is the offering from Suntour.  Sully from Rotec stopped by and let us take some spy shots before he installed this unit on one of his prototypes.  The weight on this badboy is a hefty 9 lbs (including crank arms).  But just take into account that you are loosing cassette, freehub body and chainguide.  That is around 1.5 pounds plus a pound for the cranks.  So realisticly the gearbox weighs in at 6.5 lbs.  I cant wait to try out Rotecs new creations.  He had a nice aluminum hardtail with him that was geared towards dual slalom / 4X.  Sully also mentioned talking to Weagle to get some advice on a new design that will use the Split Pivot.  Using Lawill and Weagle designs should make Rotec’s new line something to check out this next year.  Stay tuned for more details!!!
