The R3's massive BBright bottom bracket and Squoval (square/oval) tubes are optimized with the greatest possible stiffness-to-weight ratio for exceptional power transfer.

The R3 features Cervelo's Squoval chainstays that stiffen the rear end which frees the slim seatstays to act as leaf springs in the vertical plane for the ultimate combination of strength plus comfort.

Additionally, Cervelo optimizes the R3's carbon with Kevlar and special carbon stiffening plies on the down, head and top tubes for the ultimate ride every time the rubber hits the road.
