CycleOps Stackable Climbing Block for Indoor Bicycle Trainers

the climbing block is the one accessory I would recommend to anyone buying an indoor trainer. It stabilizes your front wheel for those really intense workouts and the height of one is just enough to add a little something to your workout. My only dislike is that I wish the three grooves were differing heights, but then this is also a stackable item so I should stop being cheap and buy another one if I want more height.

The seller's description of the item was accurate and sent very quick. Thanks.

This stand is perfect. It gives you a few different settings and provides stability. This is a must with any of the trainers, because it makes your bike level; otherwise you would be exercising at a serious decline.

This block helps to hold the bike a bit more steady but overall, I don't think that it is needed. Apparently, you can stack two blocks to increase the grade but I haven't tried this (I don't want to buy another block).

If you are tight on money, I would suggest passing on this item.

I went looking for more info on this product as i was curious about the "4 separate height adjustments" on the ribbon brochure and i could only see 3 possible positions. It turns out that 2 of the separate height adjustments are using a 2nd climbing block in combination with the first: back-to-back and front-to-back.

As far as i can tell there are the three positions with the one climbing block. Measuring how high the front tire is raised gives the possible height increases of 1.25 inches, 1.75 inches and 2.125 inches (these are eye-balled so not perfect).

The combination of a CycleOps trainer and my wife's bike raises her back tire 1 inch off the floor so like the previous reviewer, Adam Rhuberg said, the block is more like a leveler than a climber. Unless you buy that 2nd climbing block of course.
