I bought these to replace a broken spoke on my 17" Supermoto wheelset. Even with a lot of soapy water I could still damage them after the first use. My tire caliper/spoon bit through one. Upon closer inspection my rim had some new nicks despite use. For some reason I can't upload photos to this review. My tires didn't make much effort so I don't know why they didn't perform better . Of course, if I hadn't used them, there would have been a lot more damage.
