Apologies for writing in English, but I don’t speak Dutch, and this incident occurred in England. As this model is still in use in Belgium, I would like to warn you over there.
My Giant Explorer’s frame had a sudden catastrophic failure a few weeks ago. The aluminium frame split in two without warning across both tubes as I was dismounting, with the two wheels completely separating. It is a mere 9 years old, I bought it new, no-one else has ever ridden it, and it has not been mistreated in any way, nor involved in any accident. Being a road bike type with a built-in carrier it should be designed to carry a load. It has not had a huge amount of use, only on local roads and cycle tracks, and mainly for shopping, travel or pleasure, perhaps three times a week. It has not been ridden long distances. The tubes fractured at what is clearly a weak point, where the cables entered the tubes. This should be a warning to other owners of this model to check the frame in this area, especially the bottom tube. I was only relatively lightly injured, but it could have been far worse, even fatal, had I been in traffic or travelling at speed. I have other photos if anyone is interested in this DEATH TRAP.
