I was impressed with this Aventon Aventure, a 26″ fat tire mountain bike style that checks all the boxes for sturdy, well designed and good looking. It has an SUV vibe for sure, you feel really secure when riding. Unfortunately, none of that helps if the a fall happens, which was the case for this beast.
After the fall, it just would not shift worth a darn, and it was easy to see on quick inspection that while the derailleur itself was just scratched, the hanger was bent several degrees out of true.
So I removed the derailleur, took a ride to the hardware shop and got a long fine thread bolt of the correct diameter, and screwed it into the bent hanger. I applied some weight and leverage to the bolt, eyeballed it once, applied some more pressure, and voila, as close to perfect as I could get.
I reattached the derailleur, tightened the cable, set the high and low limit screws, and then (to my surprise) indexed the gears so that there was smooth shifting from top to bottom. I felt good that I was able to repair with having to replace anything.
But, if this were to happen again, I would want to replace the hanger, as it is softer metal, and will break with sufficient stress. But getting the right replacement is often a hassle, as each manufacturer has their own design, and with the supply chain issues we have, it can be a long wait for parts. So I think I did the right thing for now!
