In need of some help/advice.
My rear derailleur mounting screw keeps coming loose on my 2016 Giant Glory Advanced 0, bike runs a Sram X0 DH 7spd, i've tried loctite, it only lasts for a day or so. Is there a proper fix for this Sram issue?
Any help would be much appreciated.

Late answer but i've had the same problem on my 2015 Glory.
You need to dismantle the mounting screw assembly and grease it up. It's called the B-bolt, and you can buy this as a kit "B-bolt kit"

Mine had seased up completely and the derailleur was pivoting around the dropout threads. Resulting in a broken B-bolt and dropout, perfect when going for a bike vacation, 10days chainless Smile

Hey skorp, thanks for the info, but i have since found out there is a sram fix for this problem, part # 11.7518.068.000
it's to replace the T25 B-bolt with a Hex 5 B-bolt, like they have on current model rear derailleurs GX & X01 DH.

nice, was yours stuck or not moving properly when you dismantled it?

Could not find the part you are talking about, is it steel?

I have Zee on my 26er "4x" bike and a Saint on my new dh bike. they work really well, but they cant compare to a X01 dh. Crisper shifts, less chainslap and the chain doesn't jump around as much. On the X01 you always had the correct gear, my saint sometimes needs half a pedal stroke to get into the right gear again.

Got no problem when pedalling/shifting with shimano though, just these small things.

It just keeps coming loose off the derailleur hanger, it's a Sram problem, hence they fixed it on the new ones by using Hex 5mm instead of T25.

I have the same problem on my V10. I got the new 11.7518.068.000 part number and it only lasted a few days then the bushing seized up in the derailleur. Is yours still working Slash?
