The Wolf Tooth B-RAD Strap Base is perfect for when you want to carry more water or supplies on your rides. Wolf Tooth’s new B-RAD Strap Base is a versatile mount that allows riders to add a bottle cage where there once was none. The silicone-backed hook and loop straps are grippy and can easily be installed or re-positioned as needed. In addition, the Strap Base can function as a mini B-RAD base, offsetting existing bottle cage bosses by up to 22mm (.85 in) to make room for frame bags, piggyback shocks, or other accessories.
