All-natural ingredients rarely overlap with drivetrain performance, but Phil Wood's Bio Lube bridges that gap with a formula that's both biodegradable and functional. This lighter-viscosity oil positions itself as the fair-weather counterpart to Phil Wood's Tenacious Oil, which earned its reputation in mud and slop. The Bio Lube takes the opposite approach: a thinner consistency that penetrates link rollers and plates without leaving behind the tacky residue that attracts road grit on dry summer rides.

The formulation earns its eco credentials honestly. Non-toxic and completely biodegradable, it's made without petroleum-based components and wasn't tested on animals. That environmental consideration doesn't compromise the basic function of keeping metal moving smoothly against metal. The drip bottle delivers controlled application, letting you place a drop on each roller without flooding the chain and creating unnecessary mess on your chainstays.

If you're running Phil Wood hubs or bottom brackets, this lube comes from the same San Jose workshop that's been building those components since 1971. The Bio Lube works on chains, derailleur pivots, and cable friction points where a light oil does the job without gumming up over time. It also handles household duties like door hinges and drawer slides, so the bottle won't sit idle between rides.... Read More
