This stupid "tool" is a must for sram RD proper setup but the build maiteral is a real joke as so many people have experienced. I've bought one in 2022 when building a SRAM RD bike and after a couple of uses, it's left in the drawer. A few months later when it's being used again, the plastic fin first broke; then what's left got disintegerarted after still being used with struggle for a few mins.Now here in Aug 2024, I bought another one and it was already in several broken pieces inside the package upon arrival, may be due to the summer heat or being crushed en routeShame on Sram for making such a crappy item with inferior material. With so many complaints over the years, it didn't get any improvement. It's as fragile as patato chips and 100% will become even more brittle over time. If you have to buy this, please coat it with some epoxy glue which will help to hold it together better.

Ich konnte meine Gangschaltung damit auf einfachste Art und Weise wieder einstellen. Bin sehr zufrieden. Eigtl. sollte sowas gleich zum Rad dazu verkauft werden, finde ich.

After two years of riding, shifting to higher gears on my 2022 Stumpjumper (SRAM X01 Eagle AXS) was becoming problematic (delayed, sometimes indefinitely). I was able to obtain smooth and reliable shifting in two steps.1) Align the derailleur. I used a DAG-2.2. The hanger was indeed bent (it didn’t look bent).2) Adjust the B-gap of the derailleur. I used the SRAM Rear Derailleur Chaingap Adjustment Guide, Eagle 50/52t. I was surprised at how far out of adjustment it was. The guide made it quick and easy to obtain the proper adjustment.

If you understand what this is for and how to use it, this product is perfect out of the package. Cut it open and adjusted my derailed in a few minuets, keep if on the top of the tool box to prevent it from being cracked and should last me for the life of my bike or longer. Appreciate the availability!!!!

Does its job well and makes quick work of setting the tension screw.Hint: search YT for the official SRAM video on this--it's designed to be used on the 11th (2nd biggest) sprocket, not 12th as some videos show.

Helped me to accurately adjust the derailleur. Without it, I just couldn’t set correctly. First ride after using the tool, I had super smooth shifting. It’s made of plastic and a little fragile.

I was so excited about this little tool from sram, but it's broken on arrival. I used it anyways, tool is simple to use, does the job well, however, this is made with very cheap plastic. Why not use polycarbonate for water bottles? That would have been a good and inexpensive choice considering how many water bottles being thrown away every day. Very disappointed. Need a refund.Update:I felt bad leaving a bad review and thought I should give an update. Contacted seller, they are very professional! One of the nicest response I have gotten from a 3rd party seller. Received a brand new one within days. This tool might not be of best quality, but it is usable even if its broken, and it's a must have tool. Overall:This tool is 4 stars - great design, bad quality.Seller service - 5 stars

Really easy to use and it works great. BUT handle it like it's made of glass. Very flimsy and it breaks easily.
