Turning

Wheel height
3 cm
Setup
No assembly, no batteries
The JetBlack Turn Block replaces a fixed front wheel block on your indoor trainer. It holds the front wheel at a neutral 3 cm height to suit most trainers, keeping the bike level, and its top turns up to 20° each side so the handlebars can move with you.
That small amount of movement makes long sessions on Zwift and other training apps feel more natural. Your upper body is less rigid, you can shift your weight like you would on the road, and there's less of the static strain that comes from holding one position for an hour.
It's plug and play: no assembly, no batteries and no pairing. Drop it under the front wheel and ride.
