Pedals are arguably the most overlooked, yet mechanically abused, contact point on your mountain bike. They aren't just platforms; they are high-performance bearings asked to survive constant torsional loads, repeated rock strikes, side loading, and a relentless barrage of mud and grit—all while spinning smoothly for thousands of kilometers.

It’s a big job for a small axle and a few bushings. At Funn, we’ve been refining this interface since the mid-’90s, when our wide platforms helped define early gravity riding. Whether you’re on the Sam Hill side of the flat-pedal debate or the Greg Minnaar clipless side, the goal is the same: total confidence in your connection to the bike.

What is AES?

While the industry has seen many "revolutionary" changes, we believe in practical refinement. Our Angular Engagement System (AES) is built around the proven, gold-standard SPD cleat, but with a mechanical twist that changes how you interact with the bike.

• The Mechanism: AES positions the cleat at a slight angular offset and incorporates a spring-loaded rocker. This ensures the binding mechanism is always "presented" to your foot at the optimal angle.
• The "Stomp" Factor: Traditional SPD systems often require a deliberate "toe-in, then heel-down" motion. AES is designed for a flatter, more intuitive downward stomp.
• The Benefit: In dynamic riding—think unclipping mid-turn to dab and needing to get back power instantly—AES makes re-engagement noticeably faster and more consistent.

Real-World Performance: The Corner Test

In practical testing, the difference is clear. When comparing an AES-equipped pedal (like the Ripper 2) against a standard SPD-style pedal, the ease of re-engagement becomes a major performance advantage.

During cornering drills where riders unclip their inside foot to "dab," AES allowed for nearly instantaneous clipping back in. Without the system, riders often found themselves hunting for the mechanism, which can lead to missed power transfers or instability exactly when you need control the most.

Built for the Long Haul

We treat pedals with the same respect as a bottom bracket. They handle similar loads but with significantly more impact and exposure. Because of this, "disposable" isn't in our vocabulary.

Every AES-equipped pedal is fully serviceable. From replaceable axles to high-quality bushings and bearings, these are designed to be maintained, not replaced. When you’re deep in the woods or halfway through a race season, knowing your gear is as tough as the terrain is everything.
