Freedom 29 x 1.90-2.10 48mm 普瑞斯塔閥內胎

Been running these in my plus tires for a few weeks now, and the 48mm Presta valve gives me plenty of clearance through my deep rims. No flats yet even on rocky singletrack.

Finally found a tube that fits my 29er tires perfectly without that annoying valve gap. The 48mm presta is just right for my deeper rims, and it held air solid from the first ride.

The 48mm presta valve was long enough for my deep-section rims, which was my main worry. Installed easily and has held air perfectly over a few rocky rides. Only ding is the rubber feels a bit thin compared to some other tubes I've used.
