Eclipse

Eclipse produces a specialist range of TPU inner tubes for mountain bikes, offering a lightweight and durable alternative to traditional butyl rubber tubes for off-road riding. At Swinnerton Cycles, we stock Eclipse TPU tubes for MTB riders looking to reduce rotational weight and improve trail performance without the complexity of a full tubeless conversion.

Eclipse's off-road TPU tubes are engineered for the demands of trail and enduro riding, with robust construction that handles the impacts and pinch risks of aggressive off-road use. Available for 27.5" wheels in a range of tyre widths, Eclipse tubes offer a practical upgrade for riders who want the weight benefits of TPU technology on the trail.
