The triple bicycle Allen key (Y-Wrench) is a multi-tool that makes adjustments easier during the ride. It combines the three most essential sizes (4mm, 5mm, 6mm) into one ergonomic design.

• Y-shaped design: offers a comfortable, non-slip grip and efficient power transfer for loosening rusted bolts.
• Integrated sizes: cover 90% of the adjustment needs of a modern bicycle.
• Compact construction: total length of just 11 cm, suitable for storage in a saddle bag.
• Heavy-duty quality: made of durable metal with a red plastic coating for protection against wear.
