Fast gravel racing asks for shifts that land cleanly under load, and the Universal Derailleur Hanger is a UDH derailleur hanger that replaces the stock hanger on frames designed around the SRAM UDH. It mounts standard, non-Full Mount derailleurs from SRAM, Shimano, Campagnolo, and TRP across road, gravel, MTB, and EMTB drivetrains. The hanger is fully CNC-machined from aluminum. What Our Gearhead(R) Experts Are Saying:"Hundreds of shifts into a long gravel day, the indexing was still dialed in, because the hanger stays stiff under load instead of letting the derailleur drift out of line. I never had to re-tune the shifting to chase it back."
