Quetzal Misterio

[Tim Wright]

Hi, I recently purchased a second-hand ow-milage Quetzal Misterio.

More recently, it broke - the forks at the back (between the rear
suspension and the wheel) have actually bent to the side meaning that my
rear wheel no longer points in the same direction as the bike.

I was wondering if this is a common problem with this model bike, and if
so, what's the best way to stop it happenning agaon (and to fix the forks?)

Has anyone had a similar problem or heard stories (I'm worried it might
be a design defect).

I sensibly bought the bike from a good bike dealer so they've got it
back for repairs (aah, warrenties but I was wondering if there was
something I could tell them to ensure it doesn't happen again.

Pictures? Is this the same bike currently sold as the Quetzal SR:

Were the fork blades warped or did the bend occur at the pivot with the
main tube?

Did any unusual event occur; e.g. rear wheel stuck in storm sewer
grate, or did the damage happen during regular riding?

If the damage occurred during regular riding, you are either too heavy
for the bike, the frame lacks an adequate factor of safety against
plastic deformation, or there was a manufacturing defect; e.g. change
in materials, material section or improper heat treatment.

Not enough information has been presented to form an opinion.

That looks like exactly the one.

The fork blades were warped - the pivot with the main tube is fine.

regular riding - I'd stopped at some lights and when I rode off the
chain came off and I noticed that the back wheel was pointing in a
different direction.

The bike shop assured me I'm not to heavy for the bike - I weigh about
100KG.

I rang the bike shop today and they are busy straightning and re-welding
the back forks. I guess they are planning to put extra strengthning in
there but will check it when I pick it up.

At the moment, I'm assuming that it was a mistake made when building the
thing.
