Eclipse Performance Off-Road Tube — 32" × 40/65 mm valve length:50mm 60 mm + — deeper32 inch wheels carry more load, cover more ground, and until now came with one unavoidable trade off: a heavy inner tube. The Eclipse Performance Off Road 32" is 69 g up to 70% lighter than a butyl equivalent built for cargo bikes, wide tired adventure bikes, and plus size setups where the wheel size is unusual but the weight penalty doesn't have to be. Made in Germany with a patented all aluminum valve and a patented end to end welding process. Why
