The Bolt On Cache requires you bike to have bolt on top of the top tube by the stem. This bolted design eliminates velcro around your stem for a clean and secure one-handed zipper access to open and close while riding. Bolt-on option includes mounting hardware and internal velcro cover to prevent damage from contents rubbing on bolts. Please add your bolt-on spacing (see photo diagram) in comment field at checkout.

All sizes taper to help avoid knee rub while still providing a large amount storage with cord access for your electronics. Stiff foam is located on both sides and bottom. All sizes are compatible with the Spacelink (sold separately).
