WHAT GOES UP MUST COME DOWN R5 has one job—get to the top, fast. But for all the glory and fanfare that comes with a summit finish, they're rarely the only climb of the day. And while a race isn't usually won on a descent, they can certainly be lost. A climbing bike that can't carve a hairpin is a bit like a cup of decaf coffee. This is the fourth iteration of the R5, and while weight and stiffness have varied over the years, the handling, poise, and unmatched prowess on a descent have been consistent since day one.
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. - 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 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. - 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. - Balanced Handling Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.
The Tactic is a race-proven speed machine purposefully designed for carving up asphalt and dominating the race circuit. Engineered for performance with aggressive race geometry, an ultra-stiff Power Chassis, and slender ARC Race stays, the Tactic delivers the perfect balance of sprint-ready responsiveness and vibration damping compliance. You already have your strategy, execute with your Tactic.
The Section S is a stylish, nimble steel all-road rocket built around big tires and features that won't let any road interrupt the rhythm of a great day out. With lateral stiffness and shock-absorbing vertical compliance that allow for efficient power transfer while smoothing out rough surfaces, the Section S’s back tempered Reynolds 725 Chromoly frame lets you put your head down and keep your legs churning out the watts – no matter where the ride ends up. We made the Section S frame kit available to riders who have particular taste and needs when selecting components, but have given it front and rear thru-axle compatibility, direct mount disc brake interfaces, and compatibility with a wide range of drivetrain styles – 1x, 2x, and electronic. The externally-routed cables make it simple and quick to keep crucial mechanical systems running their best, and stealthy accessory mounting options make for a fast, adaptable ride.
