The 4.3\/4.4 mm double-sided wrench is a niche-but-essential tool for the workshops that service heavier-rim builds; if you've never seen a 4.4 mm nipple in your service queue, this isn't the wrench you need, but if you've ever fought a 4.4 mm nipple with a too-small wrench, you understand why the dedicated tool exists.\u003c\/p\u003e\n\u003ch2\u003ePro tip from our mechanics\u003c\/h2\u003e\n\u003cp\u003eA 4.3 mm wrench is close enough to 4.4 mm that a tired mechanic at the end of a long shift can mix them up. The result is a slightly-loose wrench that will round the larger nipple. Same trick as the 4.0\/4.4 wrench: tape one end at the start of the build, leave the other bare; the visual cue keeps the size-selection decision separate from the size-stamping decision.
