I would say 221 lb-ft! spec is 188 to 254 so for sure 221 is correct.
Right, I also did a measurement that gave me 36 but read a different thread that said 32mm. Not sure if there is a difference between Gen 1 and Gen 2, I have Gen 2I just did a rough measurement with the wheel still on of 1.390" which works out to 35.3mm which is definitely not a 32mm. Interesting nut. Doesn't have an additional sleeve and cotter pin but sleeves built in it?
