Correct, 29er. The thing is, to be really honest, nothing hit the ground as far as I could tell, no rocks, just sandy dirt on a building site. If I fell I could understand that this would happen. This is why I am so unhappy cos I did nothing out of the ordinary. according to me I did put some strain on the bike because of the angle of the hill. But none the less I will take it back to the store as it still under warranty. About the service, that's correct, it needs to go for the first service tomorrow according to date. Do you think that it might be due to the bike being "ride in"?
