A CNC-machined aluminum rail that mounts a Hailong-1, 21700, or Reention-case downtube battery almost anywhere on your frame — regardless of where (or whether) your bottle eyelets line up. The wide, flat platform gives the cradle a solid, rock-free base and bolts on with three M5 bolts.

• Machined channels accept up to 4 hose clamps to lock the battery tight (heat shrink included)
• Designed and made in Canada by Grin
