Minoura Mag 3 riser block

Our review

Levels any bike on a turbo, at a price that makes DIY moot
Skip to view product specifications

Turbo trainers hold the back wheel 2cm or more off the ground, tilting the bike and putting pressure on your hands and wrists.


This plastic block – grooved to fit narrow 700C or fat 26in tyres – levels the bike and makes bar, stem and saddle adjustments unnecessary, as well as steadying the front wheel.
