Crack in Giant Defy 2 seat tube
Bit of a worry, cleaning the bike today after a ride and I notice a crack in the seat tube. It's a Giant defy composite 2 and the crack is just where the seat tube narrows, so it looks like the bottom of the seat post may be the culprit. I'm going to visit the LBS where I bought it but I'm not massive, 65kg, but I do ride it to work over some rough roads, is this likely to have caused this? Riding over rough roads and the impact of these?
