Kuat spent years renovating his NV 2 bike trailer rack. 0 and fine-tuning it to perfection That's why we trust him to transport our bikes. Kuat was able to find ways to improve almost every feature of the NV 2. 0, each of which contributes to stable and more reliable towing than the already solid predecessor NV 2. 0. Take two mountain highway gravel or fat bikes with adjustable cradles and enjoy peace of mind with this year's heavy-duty custom bike cable locks.
