When we set out to make Project DH, we wanted to build an epic racer.  At the top of most podiums and under some of the top riders you will usually find Shimano’s premier gravity line of components – SAINT!  We spoke with Joe Lawwill over at Shimano on putting the drivetrain together for Project DH.  In the search for something new, he explained that the Saint group just isn’t ready for it just yet – its just THAT GOOD of a component group.  He said “We are focused on the XT and SLX lines right now.”   Now thats not to say that some of the technology from the other lines wont make it into the Saint line, as we can only assume that the ICE Tech rotors and a PLUS version of the rear derailleur are likely candidates to come to Saint.  But for now, “if it aint broke, dont fix it”.
