    • Reynolds Black Label 407 Carbon Boost MTB set

  • Reynolds Black Label 407 Carbon Boost MTB set

    This mountain bike (MTB) wheelset is kitted out with two versatile carbon fibre rims, so riders can enjoy fantastic stiffness and durability when climbing without any excess grams holding them back when hammering down the trails. Reynolds has also equipped this model's rims with an asymmetric profile that ensures a higher level of strength through even more spoke tension, making it more than capable of handling all the intensity of all-day epics in the mountains. Thanks to its boost axle spacing, riders will also benefit from more tyre clearance, smoother rolling performance and increased traction on their ride.

    Tubeless-Ready MTB Wheelset with Hookless Rim Profile

    Thanks to this wheelset's tubeless-ready technology, it's possible to run lower tyre pressures for improved grip, stability and smoothness as you tackle the more demanding of terrain conditions. This also means there are fewer risks of flats or punctures as you conquer your way across tree roots, debris and rock gardens. Another highlight is its hookless rim profile that allows for a no-burp tyre fit and easy inflation.

    Sapim CX-Ray Spokes and Industry Nine Hydra Hubs

    Built for performance wherever your next trail adventure takes you, Reynolds installed Sapim CX-Ray spokes to this wheelset for the ultimate combination of vertical strength and lateral compliance. As a result, this gives it exceptional toughness, so you can attack whatever the trail throws at you. Coming complete with precision manufactured Industry Nine Hydra hubs with a revolutionary .52 degrees of engagement, the Reynolds Black Label 407 Carbon Boost MTB Wheelset offers durability that you can trust.

    Black Label mountain wheels combine Reynolds' asymmetric, hookless MR5 carbon fibre rims and Industry Nine Hydra hubs to set the bar in mountain bike wheel performance. The rim design features a perfect balance of width, depth, and layup for wheels that provide ultimate durability, riding comfort, and trail hugging traction like you've never experienced before.
