Our precision handbuilt asymmetrical 34mm wide wheelsets are incredibly durable but at a respectable weight. Light enough to enter an XC race one day and strong enough for a full-on Enduro race the same weekend! The 28mm internal width maintains a modern tire profile without squaring off the side knobs too much.


For this product line, we decided to produce only the most popular and best product styles so that we can maintain inventory. DT Swiss 350, 240, and Hope Pro 4 Evo 32h 6-bolt wheelsets laced to UD Matte rims can ship within 3 business days !

* For unique hole drilling and alternate options, please contact us for special orders.

* In a addition to our standard 1 Year Warranty, Crash Replacement covers you for rider errors like chasing a big jump. This policy provides you with a 25% discount off the current retail price of the rim for up to 2-years after your original rim purchase.

  • Manufacturing process
    Our air bladders are made from a special material which produces smoother walls, result in a lighter rim, and are completely removed without harsh chemicals. They are removed through the valve hole with a unique process so that the rim does not have to be patched like traditional manufacturers use. This significantly improves the strength of the rims. Read More about our process here
  • Hand-Built
    Each wheelset is painstakingly built by hand to tension within 5% variance. Each spoke's tension rating is recorded in our system, as is the roundness and lateral tolerance.
  • Precise layup
    Each rim carries its own layup schedule documents which are followed meticulously by the layup workers. Our Engineering team creates a unique fiber orientation which amplifies the desired riding characteristics for a given rim.
  • Angled Holes
    Angled spoke holes allows the nipple to pull straight in line with the spoke for reduced stress. This results in fewer broken spokes and nipples.
  • U-Shape
    U-shape profile spreads the force of impacts and creates a more robust product.
  • Bead lock
    The small ridges on either side of the drop channel help secure tubeless tires in place. The bead lock makes it easier to seal up tubeless tires with a floor pump, and they are incredibly hard to burp.
  • Tubeless
    While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.
  • Asymmetrical
    The profile allows for equalized spoke tension which creates a stronger wheel that stays true.
  • Hookless
    Carbon fiber flows continuously over the bead area to provide the best impact resistance and a significant strength increase compared to a clincher rim.
  • T700
    Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.

Hello guys, want to order a wheel set and wondering if the red hubs are going to be available soon. Thanks

Hello Gabriel, Thanks for your inquiry. Do you like Hope pro4 boost hubs in red? If so, we can get the red hubs for you once you place the order. Because most of our customers prefer black or orange, and we only stock both color. Thanks, Lightbicycle
