R+1 frame Stiffer. Simpler. Better

1x is no fad. It’s the logical next step for road bikes. Lose the second chainring and you gain a beautiful symmetry. Nothing is offset, with a perfectly balanced downtube, bottom bracket and chainstay contributing to 30% greater lateral stiffness. Tube shapes are designed to maximise aero efficiency, and with less cabling (especially in the Alto version) streamlining is optimal and clutter minimal.

Seatstays and chainstays. Comfortably better performance

By replacing the double chain ring with a single, the chain stays complement the symmetrical design. And deliver far more bang for your buck. The unique seat stays profile is more aero and boosts rider comfort for lung busting climbs as well as handling confidence for those long, head down descents.

1x gearing. Tradition says no. Science says otherwise

Purists tell you 1x can’t provide the gears to climb effectively or to go fast. Vielo says rubbish. Top brands like SRAM, Shimano and Campagnolo have put their money where their mouth is with single drivetrains that compete with 2x. What’s more, the simplicity of a 1x drivetrain means less mechanical mishaps.

Tyre clearance from skinny up to 32mm

Optimum performance? Look no further than the 30-32mm tyres accommodated by the R+1. Proven to offer less rolling resistance and rider fatigue and, when combined with the unique features of the R+1 frame, offering greater aero advantages. The perfect pairing.
