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.
