Sunlite Inner Tube
Best replacement tube for small-wheeled bikes with angled valve access.
The angled 70-degree valve makes inflating tight, small-diameter wheels significantly less frustrating than wrestling with straight stems. While the specialized geometry limits its compatibility to specific tire sizes, it solves the clearance issues that plague most standard tubes on compact bikes.
