ONIPAX Bike Seat Clamp for Standard Rail Saddles

Perfect I've only had 2 rides with this and I can already tell it's solid and will last I bought a new seat the attachment it came with failed almost instantly The seat itself is great but I needed a new one of these and this worked perfectly

Had to replace a very old seat (non-rail type) on an old bike. I had a spare rail-type seat but need the clamp for it so ordered the Onipax. Like another reviewer, I found the Onipax a bit too big in diameter for my standard 7/8" post so just squeezed it close just a bit with a vice grip. I put a small piece of cardboard between the vice grip and clamp so as not to damage it. From then on, the installation went quick. Good product for a very good price.

This job is sometimes a pain to complete, however just take your time and do not try and force the products on or off. Worked perfectly.

Used this to replace a seat clamp on Peloton bike that had worn out. It’s a right fit, but once installed, it’s really solid.

I was adjusting my super old saddle clamp on my 80s road bike and the bolt snapped. Fortunately this seemed to be a correct replacement. I didn't realize there was an installation video on the product page, but I eventually figured it out on my own - be sure to watch the video to save you a few minutes of confusion!

I suppose it would be OK if I needed it, but it was the same thing I had on my bike seat before just didn’t fit the adapter for the seat to make it lower

Saved our riding seats. These are great. Great quality, fit, and ease to install. And they don't tilt like others. Meaning, once you have them in the spot you want, they're solid.

Does the job!

Used along with steel post to upgrade my static indoor spin up bike to a racing saddle.

The item was just what I needed to fix a bike and it came on time as expected

Product works well. My son is very pleased.
