BPW Derailleur Hanger Extension

The BPW Derailleur Hanger Extension is designed to improve drivetrain performance by offsetting the derailleur’s position. This allows cyclists to use wide-range cassettes while keeping the simplicity and reduced weight of a single front chainring setup. It’s ideal for road, gravel, cyclocross, or commuter bikes and benefits riders with double chainring configurations seeking lower gearing for steep climbs. Made from durable alloy CNC construction, it ensures reliable shifting performance, even in the smaller cogs of the cassette.
