This riser has varying heights and works well with my trainer and others as well.

This product does indeed do what it is supposed to do. It was definitely larger than I expected, but it makes no real difference. And indeed, they could have placed some numbers or something to indicate the angle increments, which is why I gave it 4 stars instead of 5. I'll give it high points for durability, though.

Upon receiving this product I was slightly disapointed to find that the levels on all 3 rivots are the same (or really really slight difference). It works thought

Item exactly as described. Not much to say about a large piece of plastic, but it does raise the front of the bike to the required level as advertised.

With the below freezing temps this is just the ticket to get my cardio work out in,inside, works great
