Pocket Bicycle Multi-Tool
Keep your wheels turning when you have the Pocket Bicycle Multi-Tool to hand. A nifty bit of kit with a ball-end hex key set, spanner set and socket tri-tool, plus other essential instruments, all folding neatly into a wooden centre.
It may be small but it's definitely strong - the tools are coated in titanium and held firmly in place with chunky bolts. Stores away in its own vintage style tin.
