The next time you need to replace your bike's rear mech hanger, consider the XLC derailleur hanger DO-A10. It is designed to fit a variety of bikes, including city, trekking, mountain, road and race-style frames. XLC has manufactured the hanger out of hardwearing aluminium, which is essential for saving weight and improving longevity and durability. The mech hanger is considered to be a consumable, a sort of fail-safe to protect your frame from damage in an event where the derailleur suffers harm from impact. This high-quality hanger will last longer and bend less than others. The XLC derailleur hanger DO-A10 has two holes to attach it to the bike at the dropout and onto the rear derailleur.
