Q-Tubes Mountain Tube 27.5

High quality Presta valve tube for 27.5" (also known as 650b) mountain wheels. The 32mm valve is perfect for most standard rims and features a removable valve core. For those riders who are running tubeless, you still need a back-up and that is where this 27.5" tube comes in handy.

Q-Tubes are known for the consistent wall thickness and strong seams. As far as tubes go, these are very durable and reliable. The replaceable valve core is a bonus in case you want to run sealant in your tube, replace a bent/faulty valve core or add a valve extender.
