Minoura Mag Riser Block 3 for Bicycle Trainers

The Minoura Mag Riser Block 3 has received mixed but generally positive reviews from customers. Users appreciate that it fits well and doesn't move on wood floors, making cycling more level and easier. It's noted to be strong with no flex when in use, but some found that it slid out on laminate flooring, requiring an additional surface underneath. Some customers found it necessary to use this riser block with their trainer, as it keeps the wheel still and level. It's reported to work well with different types of trainers, but one user found that it raised their 29" mountain bike too much. Despite this, most users find it to be a nice riser block that effectively raises the front wheel, particularly when paired with specific trainers.
