Wheels Manufacturing is making available its most popular machined derailleur hangers in three-piece packs. The packs, which include hangers that fit Specialized, Trek, Giant, Fuji, KHS, and other bike brands, don't include mounting hardware.
Dealers can purchase the packs directly from the company for $15 per pack.
Wheels Manufacturing is also allowing retailers to trade in any derailleur hangers, new or used, for new hangers. Up to 10,000 derailleur hangers will be made available through this trade-in program in July.
