Near instant hub engagement

The buzzing 120-point, three-pawl Micro Notch engagement in the Supa Drive rear hub means that the Halo 4XRs’ instant catch and drive is the first thing you notice.

The wheels are light enough to make the most of that snap for those who like to blitz between corners and jumps. The 21mm internal width rim gives enough girth to handle big tyres without wobbling and we’ve put a hard year of use and abuse into our long-termer sets without suffering any rim issues.

Halo hubs generally last really well too and they come in every axle standard you could want including a bolted stub axle option up front. Keep a spoke key handy though because they can go baggy over time. They’re not tubeless-ready without an aftermarket kit either.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
