MonbroFront Wheel Riser Block, Stabilizes Bicycle Trainer, Magnetic Resistance, Black, Road Bike

Its small, but does the job its supposed to at a good price. 4 stars not 5 as I felt the groove the tyre sits in could be deeper - if i knock the bike (when not on it) the wheel can pop out; but not a big deal to lift back on and never happened in use. Makes turbo training much more comfortable, not tilted forward and sliding off bike seat!

Not much to say, holds front wheel reasonably well even when out of the saddle sprinting...

Perfect height for my Tacx Flux turbo. Doesn't move around too much under load.

Does the job ok, nothing to write home about, it's a basic front wheel stabiliser and a budget price.

Does the job perfectly for the price.

Exactly as advertised
