RAM® Level Cup™ 16oz 飲料架，附煞車/離合器油壺底座

I was skeptical about mounting a drink holder to my bike's reservoir, but the double socket arm keeps it rock solid even on bumpy trails. The cup stays perfectly level through every lean and turn.

That gyroscopic self-leveling cup holder actually works on my Jeep's bumpy trails, keeps my coffee from spilling even when I hit a big rock. Clamp fits perfectly on the brake reservoir, and the short arm holds it tight without wobbling around.

I had my doubts about how well the clamp would fit on my bike's brake reservoir, but the included hardware made it a breeze. The cup stays perfectly level even when I hit bumps on the trail, which is exactly what I needed for my morning coffee.
