*If you've chosen D21-22 rim, please do NOT choose "No Access Hole", because no enough room inside the low profile rim for the nipple to pass through, we can't build a wheel with both of these options selected.

    * Complete wheel weights are subject to a ±5% variance.
      * Each wheelset will ship with: spare spokes, nipples.
        * If you can't find the specs you need, please contact us directly to see what we can do, we will do our best to help you.
