CycleOps Riser Block for Indoor Bicycle Trainers

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

Strangely, I ordered the riser block, but received the climbing block in the mail. Not that it matters, same price, same overall function. This product does exactly what it claims, and honestly, I don't think the CycleOps trainer can be used comfortably without it. If your front wheel isn't propped up on something, you'll be in an oddly downward facing position at all times, which I can't imagine would be desirable. One complaint would be that the different slots for the tire aren't marked or numbered in any way to let you know which setting you've used, so I feel like everytime I set up the trainer, I need to spin the block around and sit the bike in it, then look at the angle the bike is at, then reposition if necessary. It's just molded plastic, is it too difficult to have a little number 1, 2 and 3 set into it somewhere? Sort of annoying, but aside from that, the block is good. It even helps keep the bike upright while you're playing around properly securing the back wheel to the trainer.
