Runwell have perfected the 15mm spanner with the Aqualia 15. Unlike traditional double sided spanners, the Aqualia 15 has a single closed ring and a more ergonomic flat edge grip. The total length of 170mm gives you plenty of leverage for even the tightest nuts. The craftsman at Runwell have taken the chrome vanadium to a mirror finish and given the spanner a 15 degree angle, so there is plenty of clearance between you and the frame. A fine tool for track bikes, or Bromptons. 115g.
Also available in a more compact, travel friendly version, the Drip 15.
