Pro DH Rider Scott Mears has been using the Supadrive 150 on the World Cup circuit this year and has this to say:
"The new halo hub performs extremely well from maintenance to on the bike. The new hub design which allows you to remove the full free-hub and axle without any tools is just excellent, rather than pulling out the cone spanners like conventional hubs. The super paw design sounds rad and also gives an instant engagement of any gear. The hub is super light and very good to look at, slim curvy and with multiple color choices.
The hub is definitely a recommendation for full-on downhill or even an XC bike due to the lightweight ergonomic design. A breeze to use compared to other hubs".
