22.2mm Shim

The light is very nice quality. Spread of light is great. Sometimes a single button that had multiple functions can be frustrating but this setup is pretty user friendly. The mount is for a 35mm handlebar and requires an adapter for smaller diameter bars. Little inconvenient but adapters are cheap, fit well, and allow one mount to be used on many bikes. Very happy with this light, adapters, and customer support

Excellent light but for the price point it should have a few adapters. Il have wait more, pay $8 and $16 shipping. Shame but the lights the best iv had yet il put up video review soon.

I bought this to mount my Detour light on Ninebot Max G2 electric scooter handlebars. It fits great!

Great products and excellent service. 💯

The light is fantastic, but what is even more outstanding is the product support I've received. Super helpful and generous to gel my unique issues resolved. DO NOT hesitate to order from these folk. I am sold and by the way...I now have a light that puts all my night riding partner's lights to SHAME!

I purchased the Detour road light. I love this light. It's bright I feel very safe with it. When I hold it in my hands it feels like it will last a lifetime. Super solid product. My handle bars are narrow. Talked to Tom and he helped me out with a 22mm shim. Great customer service. I wanna purchase another light so that every bike in my quiver has a mount for this light.
