This evening just get my new arrival rear mudguard installed, was prepared for some difficult cut on it but surprisingly it matched almost perfect without doing any modification on my Levo 20, I don't even need to remove the bottom plastic/rubber protector, while the suspension compressed, the mudguard actually is moving away from the frame, so no worry about friction. This mudguard is designed for fork which is a long version, I am currently running a 27.5 2.6 rear wheel by the way, but for the clearance and space I think 29 2.3 should no problem as well.
