The trainer powers on and connects, but I am selling it for SPARES OR REPAIRS because the ERG mode gets stuck on extremely high resistance, making it too hard to pedal. I haven't opened it up, but it is likely a hardware/circuit board issue. Perfect for someone who knows how to fix smart trainers, or someone who needs to strip it for mechanical parts (flywheel, belt, freehub). Includes a Shimano 11-speed cassette in good condition (plenty of life left in the teeth). Heavy item, collection only.
