They’re great for making the most of your tyres and the width/weight ratio is good. The paint flakes off where I’ve dinged them (easy to ease back, 18psi tyres mean occasional dings, so be it) and they look a bit tatty after a year or 2 but I don’t care about that too much. Expensive for what they are but they do better things for my bike than something smarter, lighter and narrower. No issues with tubeless on them either.
They don’t really increase the width of tyres much, just adds volume and changes the shape, so they should fit ok if the tyres fit ok now.
