The Cradle3 from Daysaver is the holder for all potential helpers and tools for your bike, especially for the Original9 multitools and the Coworking5 extension. You can simply attach it to the frame like a tube or mini pump. The screws required for this are included in the scope of delivery. Magnets ensure that the tools are securely attached and a tube ensures that you can transport all the tools without rattling. With the Cradle3, you always have your own little workshop with you!
