Vertical-Angle Adjustable Bike Cup Holder

At 14.5 x 17 cm and approximately 280 grams, this cup holder delivers optimal balance of compact footprint and functional capacity. Constructed from corrosion-resistant stainless steel and resilient nylon plastic, it withstands UK climate variability and mechanical stress. Its U-shaped base clamps firmly to round tubes measuring 1.5–3 cm. The gear-based T-block allows incremental angular installation, ensuring consistent vertical alignment of the cup cage. The sliding block accommodates drink containers from 6 to 7.5 cm in diameter, and the red knob features intuitive left-to-loosen, right-to-tighten operation for secure, repeatable fastening.
