<span>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. </span> <strong>FEATURES:</strong> <ul> <li> <strong>Two-Position Adjustment:</strong><span> </span>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.</li> <li> <strong>Multiple Configurations: </strong><span>We designed Aspero to fit most 700c x 42mm or 650b x 49mm wheel/tire combinations. 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.</span> </li> <li> <strong>Balanced Handling:</strong> <span>Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.</span> </li> </ul> <strong>SPECS:</strong> Frame Cervélo All-Carbon, Tapered Áspero Fork with Adjustable Trail Wheels Reserve 32mm DT370, 24h (F), 24h (R), 24mm IW, Center-Lock, Tubeless Ready Axles Cervelo Indexed Thru-Axles w/ Lever, 12x100/142 Tires Panaracer Gravel King SK Folding 700x38 Bottom Bracket JY-BB 24 Crankset Shimano GRX 810 48/31 Shifters Shimano GRX RX815 Di2, 11 spd Front Derailleur Shimano GRX 815 Di2, 11 spd Rear Derailleur Shimano GRX 815 Di2, 11 spd Cassette/Freewheel Shimano HG800, 11 spd, 11-34 Chain Shimano CN-HG701, 11 spd Brakes Shimano SM-RT800, 160mm Handlebars Easton EC70AX Carbon Stem Easton EA90 Alloy Headset FSA IS2 1-1/8 x 1-1/2 Seatpost Easton EC70 Carbon Saddle Prologo Dimension NDR T4.0 Pedals Sold separately Accessories & Extras Smartpak 400A Top Tube Storage Bag
