The Avian Versus Youth Carbon fork — full carbon steerer, 20x1", 10mm dropout. This is the correct fork for youth-class frames with a 1" integrated head tube. If your kid is racing Mini, Junior, or Expert class on a frame designed for younger riders, this is the fork.
Full carbon steerer keeps rotating mass as low as possible — the difference between a carbon and alloy steerer matters more to a lighter rider than a heavier one, so the Youth configuration prioritises it. Same integrated M10 locking system as the full Versus range: no star nut, no expander plug, just a bolt that threads directly into the steerer tube. Simple, clean, and the correct way to do it.
When combined with the Avian integrated headset, the whole front end is self-contained with zero loose hardware. That combination is worth considering if you're building a complete race setup.

Frequently Asked Questions
Which Versus version do I need?
It depends on your frame's head tube and the axle standard of your front hub:
— Youth (1" carbon steerer, 10mm): Mini and Junior class frames with a 1" integrated head tube.
— Pro (1-1/8" alloy steerer, 10mm or 20mm): Expert, Expert XL, Pro frames with a straight 1-1/8" head tube.
— Pro Tapered (1-1/8"–1.5" alloy steerer, 20mm): Pro and Cruiser frames with a tapered head tube.
— Cruiser Tapered (24", 1-1/8"–1.5" alloy steerer, 20mm): Cruiser class frames with a tapered head tube.
If you're unsure which head tube your frame has, check the spec sheet or call us.
What torque should I use on the locking bolt?
4–5 Nm recommended. 5.5 Nm is the absolute maximum. Use a torque wrench. If you overtighten it, you'll strip the threads inside the steerer — there's no repair for that.
Do I need a star nut or expander plug?
No. The Versus uses an integrated M10 bolt that threads directly into the steerer tube. No star nut, no expander plug. That's the whole point of the system.
What headset do I need?
Youth: Avian or Sinz 1" integrated headset.
Pro (straight): Avian or Sinz 1-1/8" standard integrated headset.
Pro Tapered / Cruiser Tapered: Avian or Sinz tapered 1-1/8" to 1.5" integrated headset.
