Three-way Y-wrench
Most of the bolts on a modern bike are 4, 5 or 6 mm, and this PRO Y-Wrench puts all three on one tool. Saddle rails, stems, seatpost clamps, bottle cages and many brake and shifter clamps are covered without digging through a set of loose keys.
The Y shape is quicker to use than an L-key. Spin bolts in fast with the tool held by its centre, then use one arm as a handle for extra leverage when snugging them up. The grippy rubber handle keeps it secure in greasy hands.
It's a staple on workshop benches and home toolboards alike, and a good first tool for anyone starting to look after their own bike.
Home mechanics who want a quick, comfortable tool for everyday adjustments.
