Tool Storage Bottle

Birzman Tool Storage Bottle turns a standard bottle cage into secure, on-bike storage for the essentials—ideal for riders who want tools and spares kept accessible without a seat bag or stuffed pockets.

Built with an impact-resistant shell and internal soundproof padding, it helps protect contents and cuts down on distracting rattles on rough pavement and gravel.

• Standard bottle cage fit - Drops into virtually any bike’s bottle cage for clean, centered storage
• Impact-resistant body - Helps shield tools and spares from knocks and trail vibration
• Three-piece soundproof internal padding - Reduces rattle and keeps contents from clanking together
• Compact exterior dimensions - Outside diameter 74 x 135mm for easy fit on most frames
