Made an interesting discovery on the GT Bravado, one of the 
reasons i bought this frame is that it has the cool GT Groove tube, 
all the cables are run through a groove under the top tube, pretty 
neat, the German seller i bought the frame off said there was a bit 
missing to guide the cable to the front mech, no problem, i'll build it 
as a 1x8 (though would have prefered fully geared), turns out the
 missing bit is just a simple plastic tube that runs the inner cable
 over the rear seatstay bridge 
Wish i'd known this before i spent £25 on a fancy Gusset chain roller
 though  :roll:
