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.

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.

Works great! It's bigger than I expected... so better for a semi-permanent spot (thinking home gym) as it will not just slip into bag or something like the small oval ones will. I only bought the one, but by the looks of it, most likely "stackable" as described. A large stable base for your front wheel that has different heights as you rotate it and reinsert the wheel. Great product all in all.

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 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.

super stable!

Yes you can use a phonebook or any thick book but this is nicer and easier. No more book collecting mold, dust, and Silverfish in my garage. I use the highest slot although there’s not a lot of difference between the different slots. It’s lightweight but still solid. I haven’t had any issues with my bike moving. It doesn’t really raise your wheel. It evens it out.

The Saris Indoor Bike Trainer Stackable Climbing Blocks is an outstanding product that has transformed my cycling experience. Its innovative design, ease of use, and exceptional performance make it an essential accessory for anyone who loves to ride indoors. 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.
