Last spring I noticed a crack in my Cannondale frame on the right chainstay about 2-3 cm from the
dropout. The tube was nearly off. I friend of my welded it and the welding seems to be OK. My friend
estimated that the strenght has been reduced by 30%.
I will continue to use the bike and I will look for any new cracks in the area before and after
every ride.
