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

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.

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.

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.

This block works great for use with the trainer to get different front wheel heights. It's very light and very sturdy and keeps the front wheel far more stable than just trying to prop it up on something. My only complaint is that it's fairly wide, making it a bit bulky. Good value and glad to have it nevertheless.

super stable!

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.

I purchased this with the Kinetic bike trainer and i could not imagine riding without this. Not only does this hold your bike on par with the trainer, it also supports more of the front tire than the rest of the products sold out there. Keep in mind that the pressure that you are going to be placing on the front tire the entire off-season. You want as much surface area as possible so as to not put too much strain on the front rim and tire. This works out perfectly!

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.
