Derailleur Hanger 144 Fits Specific Trek Gary Fishers Bicycles with Mounting Hardware Trek Part Number 322175

I first tried a local bike shop where I bought the bike (Bicycle Village in Aurora, CO). It was going to take them 2-3 weeks to get part for which they were going to charge $25 and an additional $30-$40 to install. I went home and the ordered the part and with tax and next day shipping the price was $24 (less than what the bike shop wanted for just the part). It arrived the following day and was simple to install (less than 15 minutes including time to get tools and stand out).

Put it on my 2020 Trek Roscoe 7. Great fit.

This part is the correct one for a Trek X-Caliber 6 from 2015.I was sad that it didn't actually have the tree logo on it as depicted on the website here. I thought it looked cool. In any case it'll get the job done.

Fits into my trek Roscoe 8 pretty well, but my 12th gear is popping into the 11th every once in a while. I don't think it is a problem with the hanger, but I know its not a problem with the derailleur, so it's either the cassette or the hanger not sitting perfectly. It might be good idea to spend twice as much and get it from the trek online warehouse store or a local one just to be sure.

Item received not as pictured. Missing tree graphic

Fit my 2016 X-Caliber 8, good machining. Installed with no issues, included hardware.

works great, I will get this again when I break another hanger.

Fix my trek perfect. Haven't used it on the trails yet but overall seems very good quality. Fast shipping!
