Grand Bois Plume 650B latex inner tube
The Grand Bois "Plume" is an extralight latex inner tube for 650A or 650B tires, from 36 to 42mm wide. Tipping the scale at only 58g, it's one of the lightest tube available for these tire sizes.
Lightweight and extremely supple, these tubes will further improve efficiency on rougher roads and provide superior comfort.
We recommend the Grand Bois "Ecureuil" 650Bx38mm extralight tire for that perfect light and supple combo.
All Grand Bois tires and tubes are made in Japan.
