I'd like to plug our rear hubs.

They're based on a downhill MTB hub so the manufacturer rates them for extreme duty.

They're track threaded on both sides.

They're built with SKF bearings and crack-proof nuts.

32H, 120mm and 135mm (which works just fine with 130mm spacing).

And plenty of axle for tugs -AND- pegs.

$50 which includes shipping.
