Wolf Tooth has expanded their B-RAD line with the new Half Bottle system. This adaptor offsets the bottle mount on a mountain bike’s down tube, allowing the rider to mount other accessories, like a multi-tool and a pump, next to it.
MSRP for the adaptor is $24. The strap and accessory mount costs $30, and the rail mounting system retails for $18. More info is available on Wolf Tooth’s website.
