The Rush has a swift geometry and stiff chassis, but the smooth riding blend of lightweight chromoly tubes makes it at home on chewed-up asphalt as much as the velodrome.The current iteration has side-tacked seatstays and S-bend chainstays for more crank clearance and tire clearance. To cap off its more vintage Keirin-inspired look, we are matching the Rush with a threaded fork to allow you to equip it with a clean-looking quill stem. - Tange Prestige heat-treated double butted CrMo steel; butted CrMo rear end- Aggressive track geometry- Investment cast Tange horizontal track fork ends- Drilled for caliper brakes- One set of water bottle bosses on the seat tube- Includes threaded 1" sloping lugged crown Tange Infinity CrMo steel fork with straight blades (38m rake)- 1" headtube- 27.2mm seatpost size- 120mm rear hub spacing- Max. tire size: 32c(w/o brakes) / 28c(w/brakes) Please contact shop for complete bike/frame shipping rates!
