Just looking for some general feedback from you all on whether wheel/tyre rub and indentation on carbon bike chainstays is anything to be overly concerned with? I ride a 2010 Scott CR1 Pro with 25mm (Michelin Pro4 service course tyres) on Dura-ace C24s or Mavic Cosmic Carbone SLs.
My LBS on a recent frame inspection had declared that my chainstay was 'cracked' based on a quick visible inspection (all of two minutes). Having looked a bit closer myself afterwards, what they are mainitaining as a crack is a fairly uniform indentation in the paintwork on the inside of both chainstays in line with where the tyre is closest to the chainstay. There is not a lot of clearance for 25mms on my Scott CR1 however there is certainly no apparent chain rub when climbing or putting the power down.
Having researched on the internet, there are a number of posts identifying a similar issue either due to wheel flex or where new tyres have a rubber edge or stalks which catch on the chainstays.
I intend to get a second opinion from another LBS for piece of mind but just wanted to gauge the forum here for experience here? Perhaps I need to revert to 23mm tyres to prevent any further wear on the paint lacquer??
