Evil Nut

Are you looking to add an Old Man Mountain cargo rack or tow a trailer with your Evil? Our Evil Nut will replace the stock derailleur nut. This allows use of our thru axles designed for BOB Trailers, OMM Racks, indoor trainers, Followme or Yoke Trailers on all Evil bikes.

You will need our axle too; this is just the nut. No changes to the integrity of the Evil derailleur hanger system, and it maintains crisp shifting performance.
