Nitto B353AAF Touring Handlebar 580mm

The Nitto B353AAF is a legendary swept-back handlebar — originally developed in collaboration with Rivendell and now the benchmark for Bosco-style bars. Its massive backsweep and high rise deliver an upright, relaxed riding position that transforms long-top-tube bikes, vintage MTBs, and everyday commuters into genuinely comfortable machines.

Made in Japan from heat-treated aluminium with the immaculate finish Nitto has been known for since 1946.
