The Oi Luxe is luxe in every sense of the word. Its CNC machined ringer and brass dinger, stitched vegan leather' shim and metal injection moulded stainless steel, make it a pleasure to have on your handlebars. The Large Oi Luxe fits 23.8 - 31.8mm bars. What about the handle-bar cables No worries. Built into the shape of the mount is a cable management system. So not only does it allow the bell to look and sound uninterrupted, it also helps gather your cables (for the organiser inside us all). The Oi bell's shape originates from its home - the handle bar. Where bells usually protrude up or out, Oi doesn't. It appears to hover around the handle bars. In one sense, it's discreet. But in another, it stands out as unrecognisable. With a CNC Machined ringer and a brass dinger, the strike of the bell is firm and fast, allowing a good balance of volume and longevity of sound. Our bell actually has several pitch tones - one core and several supportive higher tones to ensure it's unmistakable and safely heard. What about getting it on the bar Just pop it over, give the hex screw a quick tighten up, and you're good to go. No sliding down the handlebars, no dismantling and re-assembling.
