CycleOps Stackable Climbing Block for Indoor Bicycle Trainers

This is a very much needed piece to complete the training setup. It keeps the bike level and stabilizes the front wheel. I feel this should almost be included with the purchase of the trainer.

The block was a little lighter than I had expected, but works fine. It holds the front wheel securely. It is also large enough that it is stable, even when I'm doing hard, standing intervals.

I was amazed by the size of this block. From the picture I would have though it was about 6 to 8 inches wide. Its not its about 12 inches wide and about 4 inches tall. I know that some people have had a hard time distinguishing which groove they were using to hold the tire steady. This is how I tell the difference between all three. I look at the yellow dot in the center and each groove has a different height from the yellow dot. Its pretty easy to see the difference from one to the other and just remember which one I used before. I am really glad I have this block and would highly recommend it. My front wheel does not move at all even when I stand up to peddle.

It doesn't matter how high your front wheel is, it will not simulate an actual hill climb because you are not working against gravity. It can only simulate your *position* on the bike when climbing a hill. If you want to simulate the important part of a climb, i.e. having to work harder to gain elevation, crank up the resistance on your trainer.

I recently purchased a CycleOps Fuid 2 trainer and bought the climbing block to use with it. It definitely stabilizes the rig and makes for a very good workout platform as you can ride as aggressively as you like and you don't have to be concerned with stability issues. It does what it claims to do very well. For those who want more incline, but don't want to buy another block, you can easily set this product on a block(s) of wood, books, etc. and you still have the front wheel stabilized in the designed "cradle" of the climbing block.

I agree with previous posters re: the lack of markings on the different cradles built into the block. I mean, how hard would it have been to incorporate an indicator of some sort ("A", "B", etc.) into the mold?
Although, I don't believe there is enough difference in the different settings to make any appreciable difference in your workout. Literally, we are talking fractions of an inch here, but still, if they are going to tout several different settings, then the settings should be discernible in some way.

I like it and am happy I bought it, so if you use your bike on a trainer, I highly recommend this product.
Stay fit, stay happy!
