Ryder Seat Post Water Bottle Cage Clamp Mount, Black, 30.9mm

The clamps work great. They keep the bottle cage, with a full bottle, very secure. I would recommend using a bottle cage that releases the bottle on the side. This way you can mount the cage high on the seat post and use the seat as a way to prevent your bottle from jumping out. I’ve ridden hard with mine and have never lost a bottle. Also take a tool with you for the first few times you ride so you can retighten the screws that hold the cage onto the clamps. Mine came loose. After I tighten them they were fine. Or use lock tight like others have.

Great quality! Work as advertised. I got them to go on my down tube but no hinge or other way to do that. My fault.

I was looking for a seat post water bottle holder to hold a second bottle on my full suspension bike and this did the trick. I was pleasantly surprised at how well it held the bottle even on rocky descents. Definitely recommend this to anyone

Arrived on time. Beautiful, solid, works perfect. No complays, it does the work. 5 star.

Works well
