These Nimbus tubes are lightweight and have taken the 36 commuter world by storm! These tubes are explosion proof and will form an airtight seal around the nail or glass, slowing down the leak. This gives the rider extra time before they have to fix the leak. ( We have even seen this tube fixed with a lighter.)
Please note: These tubes are made from unvulcanized rubber which is lighter than traditional rubber but more porous. This means it is normal to loose 5psi to 10psi a night.

Nimbus Clear Inner Tube 36"

This tube has a Foss Schrader valve. The Foss Schrader valve is required for some Nimbus rims so please use caution when buying tubes for your rim. The Foss Schrader is 1-2mm smaller than the Schrader so the Schrader will not fit without drilling. The Foss valve stem is much better quality and is a great product. I punctured this tube while putting it on the rim (getting the tire on was a pain) but this was nothing that slime or other sealants cannot fix. This tube seems to be high quality and have never had any problems with it. I would recommend this to anyone with a 36" x 2.5" rim, especially if it is a Nimbus rim!
