Quick answer
World Climbing currently identifies Perfect Descent as its Speed auto-belay sole supplier and the Speed PRO as the model used at events. The system retracts line during the ascent and controls descent, but this guide is not an operating or inspection manual.
Why Speed needs a specialized auto belay
Elite athletes climb too quickly for conventional manual rope management to function like ordinary top-rope belaying. A Speed auto belay must retract line rapidly enough to avoid interfering with the ascent while remaining a life-safety system.
Current World Climbing system
World Climbing's equipment page lists Perfect Descent as the event sole supplier and Speed PRO as the current model. The federation and Perfect Descent extended their partnership through the LA28 Olympic cycle after updated performance requirements were developed.
What the athlete should notice
A properly functioning system should allow the climber to accelerate without fighting slack or rope drag. If connection, retraction or device behavior appears abnormal, the athlete should stop and involve trained staff.
Safety boundary
Installation, inspection, service intervals, connectors, mounting, rescue and retirement are manufacturer- and facility-controlled matters. Never use this educational page as a substitute for the Speed PRO manual, local standards or trained inspection.
Why supplier status is dated
Official suppliers and recognized equipment can change. SpeedClimbing.com treats current model/supplier names as time-sensitive and directs readers to World Climbing's live Sport Equipment page.
