ULTIMATE USE Flow Aluminium Riser BarsFor its Flow Aluminium Handlebar, ULTIMATE USE adopted the same 9° backsweep and 5° upsweep of its carbon "Nail" model, but gave the Flows a 40mm rise for a more upright riding position. This geometry makes them ideal for cross country and all-mountain type riding.Multi-Butted HandlebarsThe Flows are constructed from butted aluminium, which provides extra strength in key areas and a slight amount of flex in others for extra comfort on longer rides.Features: Material: Butted Aluminium Finish: Flat matt black Bar Clamp Size: 31.8mm Upsweep: 9° Backsweep: 5° Weight: 740mm: 234g; 780mm: 227gBuy ULTIMATE USE Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
