Front Wheel Riser Block with Sturdy Wheel Holder Indoor Bike Trainer Stand for Mountain Bicycle Training Trainers

This riser block works well to level out your bike and somewhat stabilize the front wheel while using a stationary trainer. I used to use a block of wood or a thick book, but I like this better. It has a smaller footprint and looks a little better too.

This product is sturdy and non-tippable. Definitely worth the money.

Ok - this is my first experience with a wheel block, so take this with a grain of salt.1) It works. The front wheel is now raised about 1+ inches. That said, I could have used a book to accomplish the same thing.2) VERY light, very plastic (the word "cheap" comes to mind, but that would be unfair). I'd think (?) this would be more effective if it were heavier. Why not fill it with sand or something?3) With regard to stabilizing the wheel, I'd say it is marginally better than just raising the wheel on a book. It's not like the wheel moves around a lot while on the trainer, so...

Keeps me sturdy with my trainer. Used on Carpet so can't speak to wood, but worked just as intended on a street tire for a fixed gear on carpet.

This is what I need...inexpensive, yet effective and does what it's supposed to do.

works as described.

barely holds the standard bicycle tire. and is not slide proof on hardwood floor

Nice front wheel riser block that serves its purpose really well. It is sturdy molded plastic with a graduated interior design to fit both road bike tires and mountain bike tires, and it has non-slip integrated rubber skid pads to protect from floor damage. It sufficiently raises my front tire for a more natural riding position when I have my bike positioned on my bicycle indoor exercise trainer. I would certainly recommend.
