Frames

HAUL ASS, NOT CARGO We engineered Áspero for pure, unapologetic speed, ready to take down finish lines, KOMs, PRs, and FKTs. A bike built without limits, for the riders looking to test them. It’s stiff—Classics-racing stiff—and performs like you’d want a road bike to perform off-road. We think that makes sense, and it’s what we were trying to do when we were stuffing bigger tires into our existing frames and swapping in aftermarket forks to get a 40mm tire up front. TWO-POSITION ADJUSTMENT Trail—front-wheel response to rider input—is the most critical factor in high-velocity handling. Flipping the two-position "Trail Mixer" to compensate for the difference in circumference between a 650b and 700c tire maintains consistent handling by maintaining consistent trail figures. MULTIPLE CONFIGURATIONS We designed Aspero with clearance for up to 700c x 40mm tires or 650b x 49mm tires. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame. **New Shimano road (not gravel) 12 speed front derailleurs reduce tire clearance in the rear of the frame to 700 x 38c or 650b x 45c** BALANCED HANDLING Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.

The S5 prioritizes aerodynamic performance and stiffness, making it a platform preferred by the fastest sprinters in the world. You've no doubt noticed the now-iconic V-Stem. We optimized that shape to deliver the best possible performance in the wind, hid the cables inside, and made enough bar/stem/stack options to fit just about anyone. It'll clear 28mm tires, too so you can eke out even more aero advantage.

The Soloist. It's a name from deep in our history, but immediately familiar to anyone with bike racing memories extending back to the early-2000s. It was the weapon of choice for top World Tour contenders on CSC and the Cervelo Test Team, and we're bringing it back for a new generation. The new Soloist is designed for the week-in, week-out rider and racer who can only justify one high-performance bike. It balances light weight and aerodynamic advantages to deliver a bike that really is 'just right'. Soloist comes in a hair lighter than S5, but significantly more aerodynamic than R5, and borrows the threaded bottom bracket standard you find on the R5-CX. It's a race bike that can accommodate mechanical and electronic shifting, can hammer out the training miles in all weather, and yet still has the chops to leap off the front at that decisive moment. That's the Soloist.
