If you ride a bunch in the backwoods, or are into bike camping, this bottle cage is the best thing going to stay hydrated. It can hold a 32 or 48 oz Nalgene or similar sized bottle from Hydroflask, Kleen Kanteen, etc. It will hold that weight under all but extreme mountain biking. For gnar trails, add a Voile strap and you are set. Ideal for steel frames with beefy water bottle mounts. Mountable to 2 or 3 bottle bosses. US made. Stainless steel. The black ones are stainless that’s powder coated. Pairs well with a King Cage, as far as looks go.
