Mountain bikers with GT bikes, listen up - if you've bent or broken your derailleur hanger, this replacement is exactly what you need to get back on the trails! This is Hanger 94, specifically designed for GT models like the Aggressor, Avalanche, Hans Rey, Carbon Marathon, and compatible with KHS bikes using hanger 276. It replaces GT part numbers ATIDH0239, ATIDH0246, and ATIDH0071. Now, super important - this isn't a universal hanger, so make sure it matches your broken one before ordering. This version has a threaded hole and uses an M8 x 12 chainring bolt for installation. The design is precision-cast to fit perfectly with your frame's dropout, maintaining proper derailleur alignment for smooth shifting. Having a spare hanger is one of those smart moves every mountain biker should make - these things are designed to break before your frame or derailleur does in a crash, saving you from much more expensive repairs. The quality matches OEM standards, so you're not getting some questionable knockoff that might mess up your shifting. The set of 2 means you've got a backup for when (not if) you need another one down the road. Whether you're tackling technical trails or just want to be prepared for the inevitable mishap, having the right derailleur hanger on hand can mean the difference between a quick trailside fix and a long walk back to the car. Seriously, this is cheap insurance for keeping your bike running smoothly.
