A friend of mine pointed out to me last week that my right seat-stay appeared to have a crack (must - not - shoot - the - messenger...). Sure enough, it's got a nice crack all around the perimeter. My Raleigh bike is an older carbon model. It's served me very well these past two years, but I'm not sure if I can justify a large repair expense - I only spent $1000 on the bike (marked down from $2000) when I got it. I'm in Pennsylvania - any tips on where to get it repaired, and what to look for in possible repair options?
