Tight lockring, but loose sprocket ?
Hello!
I've recently installed a Shimano Deore m5100 11-51t 11speed sprocket to my mountain bike. My rear hub is a Shimano TX505.
I've tightened the lockring with the recommended 40nm, with a torque wrench.
After like a 5km ride on a bumpy road, I'm able to "rotate" the chain rings individually from each other on the hub, but just for like 1-2mm.
The interesting part is, my lock ring is still tight. I can't tighten it more with 40nm. If I tighten them with 50nm, it will be fine for another 5 kilometers, and then same thing.
I've allready tried to replace the included plastic spacers with steel ones, and looked all over the internet. The lock ring is not nesting on the top of the hub, it's pushing down on the sprocket. No broken rivets on the spider.
I dont have shifting problems, but I'm concerned if I keep riding like this, it will damage the hub and/or the sprocket.
Is it fine like this? Do anyone have an idea or a solution?
Thank you!
