The Deuter Triangle Frame Bag offers lightweight, secure, and easily accessible storage for the well-stocked cyclist. The 1. 7-litre capacity allows you to hold everything from a first-aid and tool kit for long-haul rides to your wallet, keys, and phone for commuting and casual weekend cruises. Three Velcro straps hold the bag securely in the rear frame triangle, meaning your essentials are just an arm's reach away. A great alternative to backpacks and baskets! Please Note: Dirt getting under the Velcro fastener can scratch the frame. Please protect your frame accordingly before attaching your bike bag.
