The Horizon Attitude is a 1992 made frame according to frame nbr. It also has thinner seattube with 27.2 seatpost & 31.8 FD clamp where the 1993 model has 31.6 and 34.9 respectively.
The stickers are like 1993 though.
Very nice collection mate, well mainly the Klein's anyway I am jealous ...
They must have changed the decals early accross the range my Quantums are both 1992 build (Aug & Oct) but have '93 decals.
Thanks, though it has been changed quite a bit after the last comment made in 2008.
Anyways, your Quantums are actually 1993 models since they're made after summer holidays of 1992. That's when the factory started making models for the next model year.
