Determining length of rotor cranks

Triathlon Forum

I have a set of rotors, they are stamped with 70FGB at the ends, does that mean they are 170s? If not, where does rotor stamp the size on their cranks?

Hi Nebmot,

You got it, 170mm.

Rotor used to engrave the whole length (“170”), but wanted to use a couple of digits for other purposes.

Thanks Damon.

Good question! I just ran downstairs and checked mine, and my first numbers are 72. I guess this means 172 cranks. I had measured shortly after buying the bike and thought they were 175. Nice to know.

Yes that means 170.
