UDH - the abbreviation stands for Universal Derailleur Hanger - is designed to simplify what can be quite complicated on a bike: Replacing a defective derailleur hanger. These anchor points for the derailleur are designed as predetermined breaking points so that only this small part breaks off and the whole frame doesn't roll off towards the graveyard. Depending on the manufacturer, the search for the right spare part can be very simple, but also very time-consuming. Not only are there countless different derailleur hangers, there are also some that are very similar but don't fit.

Sram now wants to put an end to this: the UDH naturally fits the company's own shifters and rear derailleurs, and also works with shifters from Shimano, Box or Sunrace. Sram is trying to establish a standard here, there is no license on the part, so the way could be clear for many manufacturers to install this derailleur hanger. The Sram derailleur hanger is also cleverly designed: In the event of hard impacts, it should be able to deflect backwards and prevent damage to the rear derailleur. It should also protect the frame from chain jamming and, at 15 euros, is easy on the budget.
