The Avian Versus Pro Fork steerer tube is made of 4mm thick 7005 aluminum. It features a M10 thread internal locking system to eliminate expander plugs & star nuts that often compromise fork strength. The aero carbon fiber legs are made of highly durable Toray fiber, and the alloy drop-outs are available in your choice of 10mm or 20mm. This fork has a 1-1/8” steerer to accommodate frames that do not have a tapered head-tube.  

The Versus Pro Carbon Fork is compatible with BMX racing frames that do not have a tapered head-tube. Although with the right bearing race, this fork is compatible with a tapered head tube, it is highly suggested that you would use our Versus Tapered fork model.
