The Maravilloso Race XPR-3 wheel system features XERO flat stainless spokes that slice through the wind like a hot knife through butter. It creates similar effects as a disc wheel against the airflow from straight ahead, which has been proven to be very effective in the wind tunnel tests. But it does not create drag like a disc wheel when side wind is introduced. XPR-3 utilizes straight pull pattern with SPS-91/35 hub.
The 4 seal bearing hub SPS-91/35 is interchangeable with Shimano 8, 9, 10 speed, or Campagnolo 10 speed cassette body. Can be sold seperately from XPR-3 wheel system.
Weaknesses: Rubbish after care, can't get parts, never worked right!
Bottom Line:
I've had my maravilloso wheels for more than 2 years now, admittedly they are not quite the same as these but they've never worked right and I've now been waiting for new parts for over 3 months. The wheels have NEVER! been right
