It completely replaced the rear disc brake mount. Fitted perfectly. It's very strong.
Rear Disc Guard - 690/701
More substantial than expected and terrific design.
I put rear disc guards on every bike because your front wheel hates your read wheel and it throws giant rocks at it which always hit your disc guard. I bent this one on ride #1 and there's still 2mm of gap between it and the disc. Huge save for my ride, will buy a new one soon to replace it for the next rock that gets tossed at it.
Have not put it to the test yet, but I am sure it will do the job. looks great, well-made and fit perfect. Vanasche was great to do Business with, shipped fast and on time thanks again!
