I just bought a Merlyn 11a and will be racing it for the first time very soon. I'm wondering if I need to replace my donuts immediately. I see some metal beginning to show through the rubber but it's in a spot where the rubber appears to be very thin to begin w/, so I'm not sure if it is really a structural concern. I'd like to be able to make it through the first race weekend as is b/c i don't have a lot of time to change them out between now and then, but I also of course don't want to blow one knowing that's definitely not a good situation. Picture attached...
Thanks guys
