These bikes came with suntour xce kit. The cranks been unusual in that the ring are mounted from the rear leaving a flush spider like mavic star road stuff. Also worth noting is that the whole group been labeled xce but the cranks are made by sakae the brakes by diacompe leaving only the mechs(rear mech xcsport) and x-press shifters made by suntour. hubs are sansin(suntour) with araya rx7 rims. I always find it crazy with so many brand names been produced by the same company if you know what i mean! Would love to see a catologue pic
