SPINGO Metal TPU Inner Tube MTB 29 Inch / 27.5 26 Bicycle Pack of 2 Ultralight with Presta Valve 48 mm (MTB Inches x 2.1-2.5)

【Wide MTB Fit with Metal Presta Valve】Designed for mountain bike tires from 29" with 2.2–2.5 width, these SPINGO TPU tubes are built for common MTB setups. The 48mm metal Presta valve offers a secure, reliable fit for most compatible rims. 【Lightweight Upgrade for Faster Riding】Compared with traditional butyl tubes, TPU tubes help reduce rotating weight, making your bike feel quicker, lighter and more responsive on climbs, technical trails and fast race sections. A great choice for XC, trail riding, enduro training and race-day performance. 【Compact Spare Tube for Trail & Race Use】The size of a single package is only 4.13" × 2.55" × 1.95", taking up far less space than a standard butyl tube. Easy to carry in a saddle bag, frame bag, jersey pocket or hydration pack, so you can stay prepared for flats during long rides or MTB events. 【Durable TPU Material for Demanding Terrain】Made from high-quality TPU material, these mountain bike inner tubes are designed for lightweight performance, flexibility and dependable air retention. Ideal for rocky trails, forest routes, gravel sections and everyday off-road riding when installed correctly. 【Ride Prepared with SPINGO Support】This 2-pack gives you a practical spare solution for training, racing and weekend trail rides. If you have any questions about installation, compatibility or use, our support team is ready to provide technical guidance and responsive after-sales assistance.
