Soloist Ultegra Di2 R8170 Bicycle
Description
Cervelo's original Soloist design took it's cues from the their earliest pure NACA aero triathlon bikes. It evolved from aluminum to carbon and eventually became the S-series, winning podiums and stages at every step. The design evolved and NACA shapes became the squarer D-shape flat back improved tube shapes that also added more torsional stiffness and some more compliance. Cervelo has recognized the need for a new Soloist, one designed with beginning and developing racers in mind, along with every day enthusiasts who desire the best blend of aerodynamics, comfort, simplicity in adjustment and service. Now the reimagined Soloist hits the scene, at a reachable price point, great build options, and carrying the the essence of Cervelo's history and dedication to the cycling experience. Built here with a Shimano Ultegra Di2 12-Speed / Hydraulic Disc groupset, carbon aero Reserve 40|44 wheels, and a sensible build overall, the Soloist is ready to carry you forward!
The return of the Soloist was just a matter of time. Ideally placed price wise, and engineered with clean aerodynamics taken from the S5, but counter-balanced with elements of the R5, including the geometry, the Soloist is the perfect option for an everyday road cyclist who seeks speed and enjoyment while powering through a 2-hour favored loop. It is also the ideal bike for developing cyclists learning to race and applying their physical abilities to get stronger, faster, and more comfortable taking corners at speed and riding in a tight peloton.
Design features of the Soloist favor the modern cycling scene with clearance for wider rims and 34mm road tires if desired. While having a super clean cockpit and internal routing for either mechanical or electronic shifting, a new headset system allows the rider to swap and adjust stems easily, without having to bleed disc brake lines. Compliance comes from the R5 tubeset and lay-up influences, and pedal power transfer is exceptional via the asymmetric chainstays and BBright T47a threaded bottom bracket junction. This Cervelo-specific T47 system is easily removed for cleaning or maintenance, and if properly fastened in place, should be dead quiet. A thrill to ride, easy to adjust and maintain, the Soloist is back, but better.
Shimano's updated and improved 12-Speed Ultegra Di2 system is lighter, faster shifting, and even more precise than ever, with improved hydraulic disc brake response. Cervelo's Reserve 40|44 aero carbon wheelset rolls with fast responding Zipp ZR1 hubs on Vittoria Rubino Pro TLR G2.0 28mm tires. This Soloist was built for race-level performance and speed out of the box, and delivers on Cervelo's commitment to creating the most efficient, best riding road bikes to more cyclists.
