Ochain measurably reduces pedal feedback and chain turbulence to enhance perception and amplify focus. Its ability to “quiet the chaos” we didn’t even know was happening is soothing and surprising. It’s as though our feet come alive, able to better connect with the bike, to truly feel what’s going on. Like never before.
By allowing the chainring to rotate backward, Ochain decouples the rider from all three forces of pedal feedback. A simple, spider-based solution that greatly enhances suspension feel, stability in rough terrain, and traction while braking and cornering. For more confidence, more control, and less fatigue.
With a simple turn of a dial on Ochain R or S, or a travel chip swap on Ochain N or E, every Ochain model can be tuned for different terrain types, ride styles and bike designs. Designed for the full range of trails and machines, from short travel and highly versatile, to DH-specific and free ride. Because all riders deserve this feeling.
Studies prove that when the bike is moving faster than a walking pace, forward wheel rotation compensates to negate what’s known as “pedal kickback.” So even though pedal kickback rarely happens on the trail, Ochain still eliminates it.
A significant source of pedal feedback, Cassette Backwards Slap occurs on all mountain bikes when the chain bounces. This causes the cassette to roll forward, then “slap” backwards, which tugs the chain and crankset with perceivable force at the rider’s feet. This high-frequency event is no small disturbance, but by rotating backwards, Ochain controls this feedback, letting riders better feel their suspension and trail without distraction.
To counter our weight naturally shifting forward under the decelerating forces of braking, every rider unintentionally presses against the pedals. While totally normal for all bike types and rider levels, when combined with what the rear wheel is doing under braking, it exposes a stark reality. Data and slow motion footage shows that as the wheel comes off the ground under braking, it locks up for an instant, and so does the cassette. This momentary lock up transfers directly through the chain to the crankset, creating firmness under the rider’s downward pedal pressure—producing pedal feedback. As the wheel contacts the ground again, it releases. With Ochain, all these forces from rear-wheel lockup are drastically reduced, allowing riders to feel a lot more stable. Which leads to a lot more confidence.
Even if it creates tension with sponsors, even if they have to pay for it themselves, many of the fastest World Cup pros today won’t ride without Ochain. Look at their bikes, and you’ll see. Ochain equipped bikes won the 2025 women’s and men’s elite DH World Championships, as well as both World Cup overall titles.
Because Ochain is mounted on the crank spider, both descending and pedaling performance remain consistent, regardless of the gear you’re in. When you consider that hub-based options sacrifice points of engagement to provide travel, and also suffer from inconsistent travel that is either amplified while climbing or reduced during descending as the gear ratio jumps up or down, the choice is even more clear. Ochain gives you consistent and reliable, crank-based travel. And for maximum efficiency, pairing Ochain with a high point of engagement (PoE) hub removes any variability from the transmission of power, key for technical climbing.
External Travel Adjust (Ochain R and S) lets riders fine-tune the amount of travel with a simple turn of a dial. Choose 0º, 3°, 6°, 9°, or 12°. Go for more or less to match terrain, riding style, and bike setup.
The Ochain External-Adjust Upgrade Kit lets Ochain N and E riders swap to a dial-adjust faceplate that works just like Ochain R or S. With a premium finish to match Maven Ultimate and Eagle Transmission, riders can tune degrees up or down, right on the trail, for max efficiency on tech climbs, or max feel on the way down.
By combining premium-grade aluminum with an optimized wall-thickness design, it’s beyond DH tough, but still light enough for any gram-counting trail rider maximizing performance.
Full Ochain service intervals align with suspension service (200h of ride time) and can be done by most home mechanics. Thanks to a new sealing system, expect nothing less than super low contamination and super high performance between those intervals.
