Saris Indoor Bike Trainer Stackable Climbing Riser Block – Adjustable 3-Level Design for Stable Cycling Training – Compatible with Rear Wheel-Mounted Trainers

My wife and I had the cheaper Sunlight block for her bike, and that one was fine but definitely on the cheaper side. She got bigger tires for her road bike, and the other block seemed to have a hard time keeping the tire in place. When we moved to our new apartment the block went MIA, so I decided to order this one. When the boxes arrived (I ordered two) we were definitely surprised - I didn't think they would be quite so big. But they really do a great job at giving us a stable ride when we're using our bikes on a trainer. Also, the fact that the two blocks can stack to create a more strenuous workout is really neat. They're a little pricey (to me, anyway), but if these were to get lost during our next move I would feel comfortable spending the money on them again. They're very well built, very stable, and make me feel very comfortable on my bike. I'm 5'10" and around 200lbs, and my wife is 5'5" and 130 - both of us feel very stable on our bikes, even when we're in higher gears and peddling quite fast. We clip in to our pedals as well, and where the other block made me feel terrified of tipping over at any moment, thankfully this one doesn't give me the same dread.

Great item for the money.

Lightweight but high quality, stable unit. I bought this go go with my CycleOps wind trainer. Glad I did because otherwise I'd be riding downhill the whole way. Yes, this is a "leveler" and you would need to stack another to go "uphill." Keep in mind that if you raise the entire bike up, it may be harder to get onto the bike if the top beam of your frame is already high for you. Can't imagine what could be better. Recommended. Update: I still think think this is a great item and worth buying with the trainer, but more for stability than leveling. The trainer only raises the back wheel a little bit so the downhill sensation I was worried about isn't so much of an issue. The bigger problem is that without this item your front wheel may be wobbly.

This CycleOps Stackable Climbing Block essentially does what it is supposed to do. It raises your tire to simulate climbing a hill. First things first. If you purchase just one of these to use with a trainer, the best it will do is raise your front tire even with the back. Indoor bike trainers raise your tire, and this thing merely raises the front to be level with the back. You would have to stack them (they are stackable) to achieve any height. This being said, I don't see how stacking these things would provide a harder workout. With my wheel on the ground, I do not feel as if it is easier than in the block. You're not fighting gravity like if you were walking/riding up a hill (or on a treadmill), so I don't see how this "climbing block" would simulate that. It simulates the position of uphill riding, though, and maybe that's all some people are looking for. In addition, the levels (there are six, supposedly) are not marked. Therefore, unless you mark it yourself, you have no way of knowing what slot you had it in. Small quibble, but a quibble nonetheless. Lastly, it WILL slide if you want it to, but it is VERY stable. It does the job I wanted it to do perfectly, which is to level my front wheel with my rear on an indoor trainer. It doesn't scuff up my hardwood floor, and that is a definite plus. Overall, I am pleased with the construction and usefulness of this product, for what I use it. It is sturdy, well-built, and does not mar the floor. On the other hand, it is not well-marked, and it doesn't seem to simulate a "climbing experience." I didn't figure it would, though, so I am pleased with my purchase.

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.

The Saris riser is a perfect complement to any trainer. Some riser put most of the pressure on the front and back of the wheel where this unit provides ample support to prevent causing issues with creasing the tire or affecting tube inflation. It may take up a bit more space than the other units but it’s worth the space. A nice design of the unit is how you can stack multiple units, essentially crisscrossing them to create a hill climb effect. While standing up on the pedals and pushing hard, the unit keeps great stability to the front end. Finally, the price point is good for what you get.

The CycleOps block works exceptionally well as a lightweight, durable, and sturdy wheel support for spinning. I've been using this with my road bike for a year now, and it goes great with my TACX Cycleforce Basic trainer. There are multiple options to get your frame just where you want it, and it holds your wheel with no wobble, even when climbing out of the saddle. Spinning indoors is a great way to improve your pedal stroke, increase leg power, or do single-leg work safely. It also helps in working on body position. Get a quiet fan and an interesting training video, and spin away. I have not yet purchased a second block to take advantage of the stacking feature - one seems to accomplish all I need it for. Highly recommended low-tech tool with nothing to break or malfunction.

super stable!

The Saris Indoor Bike Trainer Stackable Climbing Blocks is an outstanding product that has transformed my cycling experience.

Whether you're a seasoned pro or a beginner, this stabilizer will give you the confidence and stability you need to enjoy the ride. I highly recommend it to anyone looking to take their cycling to the next level. Rating: 5/5 stars

Sujeta perfectamente cualquier rueda

Cumple con la función, ayuda mucho a estabilizar llanta delantera

Works well.

Un poco grande, pero la propuesta para tener diferentes alturas para provocar un pedaleo variado es bueno.
