absoluteBLACK Oval 104 BCD Chainrings for Hyperglide+ are designed for any cranks that use a 104 BCD mounting interface. These chainrings will only work with Shimano CN-M9100, 8100 & 7100 Hyperglide+ chains due to different thickness and shape of the teeth. They are crafted from CNC machined 7075 aluminum, and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2 - 14.4%, with timing of 110.5 - 116.3° after TDC (top dead center).

Makes switching chainrings very easy… although you do need a specific tool for the job.
The new price for a replacement for my gen2 is silly. This one is better price and works, you just have to swap the bash guard and bumper at top. This is a better price and I also got a sale discount. much more reasonable. Thanks!
I'm glad I bought these guards. They do what they're made for: No more bruised or bloody ankles from smacking rocks or cranks. I do have to say, however, that the photo seems a little misleading to me. I thought these would have a smooth finish like other G-Form products, based on the photo. Instead, they are fabric, so only time will tell on durability.
