French startup targets niche climbing market with certified solo device
French startup Roc Amadeus has launched the first CE-certified lead rope soloing device, targeting a high-margin outdoor equipment niche left vacant for nearly two decades.
Roc Amadeus, a French startup founded by Wolfgang Putzhammer and Stéphane Mauvais, has released the Roc Solo. The device is designed for lead rope soloing, allowing climbers to ascend without a partner while maintaining safety during falls.
The launch targets a specialized outdoor equipment segment that has lacked a dedicated commercial product since 2008. That year, manufacturer Rock Exotica discontinued its Silent Partner device because it was unprofitable, leaving a gap that drove secondary market prices above $1,000.
Roc Amadeus is attempting to professionalize this niche by establishing a new European safety standard. The company created a specific certification for lead rope soloing devices, making the Roc Solo the only product in its category to carry a CE mark.
The concept originated from a personal equipment failure experienced by co-founder Wolfgang Putzhammer. After a standard belay device failed to engage during a fall in 2018, tearing tendons in his foot, he sought to engineer a more reliable self-belaying system.
Priced at $620, the device commands a premium justified by advanced manufacturing and small-batch production. The side plates are machined from single pieces of aluminum, and the internal mechanism uses four steel rollers instead of the traditional two to distribute fall loads.
This engineering has been validated through rigorous stress testing. The device survived a factor-two fall with a 265-pound load, generating an impact force of 10.29kN, and withstood over 1,000 factor-one falls with a 175-pound load with minimal cosmetic damage.
Professional climbers are already adopting the gear for high-stakes ascents across Europe and North America. Pete Whittaker used it for an 800-meter first free ascent in Norway, while Brent Barghahn noted its superiority for catching upside down falls on roof routes.
Roc Amadeus currently produces the equipment in small batches to maintain strict quality control and ensure no corners are cut. The company plans to expand its distribution network with a United States release scheduled for October 2026.
