What's the size of the two nuts holding on the Axle? I'll need to purchase a new wrench. Grr!

Thanks!

 

I think they're 50mm. I bought a couple of cheap tools that worked just fine. One was a 2" wrench for $9 that worked (was a tad too big, but still fine for the inner nut) and an 18" adjustable from JC Whitney for $18 that worked even better.

 

I used a pipe wrench to replace my stock axle with a DuraBlue X-33.

 

They are 50mm.
