Park Tool - SW-40 & 42 - Four Sided Spoke Wrenches

Park Tool SW-40 and SW-42 Four-Sided Spoke Wrenches

Four sided spoke wrenches that grip on four flats instead of three. That extra contact gives more support and helps stop alloy nipples slipping or rounding off. The SW-40 is the same size as the black SW-0, the SW-42 matches the red SW-2. Not sure it fits your bike? Talk to us and we'll check.
