The hub has been machined to remove excess material and make it as strong and light as possible. Nukeproof have increased the thickness of pawl springs in these hubs to give secure engagement on every pedal stroke.The 6066 alloy rim has been extensively to ensure it is a rim which is light enough for aggressive trail riding but strong enough for DH. Nukeproof have used J-Bend spokes meaning tensioning and spoke replacement is much simpler than using a straight pull spoke.The wheels come taped with tubeless valve installed so all you need to do is add sealant and your tyre to get a finished tubeless setup. The valve supplied is Nukeproofs Horizon valve which also has a core remover built into the cap. This valve is also compatible with tyre inserts like Nukeproof ARD.
