R+1 Road Bike
We’ve seen the future, and it’s 1x pure and simple. That’s proven by the growing interest in road bikes with wide ratio, 12 and 13 speed drivetrains and single chainrings.
Our single-mindedness gives us greater focus. And resulted in the R+1, a road bike with breathtaking per- formance, efficiency and comfort. Available in an Alto 880g frameset for wireless shifting and a Strato 1100g frameset with cable ports, the R+1takes some beating - whether pumping along the flat or powering up a Col.
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.
Comfortably better performance
Seatstays and chainstays
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.
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.
Bars with cable-ability
Vital statistics: Carbon fibre 385g, 6° flair, 80mm drop. Plain English: Excellent performance and comfort by being rigid in the right places and compliant where needed. With seamless internal cabling and CNC alloy stem section for stiffness and safety, these are the perfect fit for the R+1 frameset.
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.
The Powershift hub.
Powershift Technology is a wireless shifting system that allows you to shift gears instantly, under full load (up to 1000 watts). Coupled with the Classified Poweshift hub that provides 12 exra gears without the need
for a second front chainring and derailleur. The complete system outperforms traditional 2x systems.
Optimising the groupset
Vielo crankarm and chainrings
Specially tweaked chainrings and cranks bring out the best in the R+1 frame. Vielo chainrings are used with SRAM builds and forged at high tolerance from solid billets of 7075 alloy for maximum stiffness. They’re direct mount and available from 38 to 50 tooth. If you prefer, Vielo drop-forged alloy crank arms are teamed with Shimano builds. They offer incredible stiffness and come in a choice of 170 to 175mm.
For the ultimate R+1 experience plump for SRAM groupsets. Smooth, precise and effortless, their cutting edge technology makes 1x the new normal - and riding an absolute joy. Choose from Red e-Tap AXS 12sp or Force e-Tap AXS 12sp wireless groupsets.
Need we say more
Coupled with our Vielo Crankarm, the Shimano GRX groupsets deliver slick performance at sick prices. With optimised gearing options and a quiet, stable action they’re a byword for reliability. Choose from GRX Di2 11sp and GRX mechanical 11sp.
Dare to be different
With the EKAR mechanical 13sp, Campagnolo have entered the 1x race with a bang. High performing, light and reliable, this EKAR groupset boasts an exceptionally wide ratio rear cassette, stiff cranks and a sweet price point
On the road
Weighing in at just 880g, the R+1 Alto frame comes with two SRAM groupset options and Zipp 303s or DT Swiss ERC 1400 wheels as standard. Choose wheel upgrades and other custom options to create your perfect Alto in terms of build and budget.
Tipping the scales at 1100g the R+1 Strato frame comes in a number of variants: two Shimano groupset options with DT Swiss ER1600 / E1800 wheels, or the Campagnolo EKAR groupset with DT Swiss ER1600 wheels.
