On Sale! Boxxer Offset Crowns (2010-2018)



Future proof your bike and gain more front end grip! These crowns give you more stable handling, like a slack head tube angle except without the compromises. The offset adjustment ranges between -10mm to +8mm compared to the stock offset.

The Outsider Bikes adjustable offset crowns have been tested and fine tuned since 2016 with pro riders Kiran MacKinnon and Nathan Riddle.

The weight, strength, and stiffness are on par with the stock crown assembly.


  • Upper and lower crowns
  • Steer tube
  • All 3 insert options

Please read the Insert Selection, and Assembly pages before installing your inserts.

The stem positions are located at +8mm, 0mm, and -8mm. You can use the corresponding inserts so the stem tracks your offset to maintain the same stem reach, or you can position the stem wherever you prefer.
