I made a mistake ordering a nipple wrench.

But I figured this was a good opportunity to replace it anyway.



↑Looking closely, the grip is worn down too, and

most importantly, the square hole is worn out.
It's the same product number, but the specs are different.
The new one I got this time has a deeper square hole.

DT nipples come in three lengths: 12, 14, and 16mm. The standard is usually 12mm. The 16mm is what they call a long nipple.
Sapim's standard is 14mm, so the new spec is designed with Sapim in mind.
