Kleins are one of those brands that to some they are highly desired, but to others it might as well be a RoadMaster, some think the brand is highly collectable because there was one hanging on a wall in the Jerry Seinfeld TV show, others say "who's Gary Steinfield?".

Apart from that they are aluminum frames for the most part, and in spite of that I'd like to have one some day. I was in a NorCalif bike shop once years ago when some Klein Reps brought in a prototype Klein with the huge single bubble tube beer can thin aluminum framed MTB. The shop guys were taking turns flicking it with their thumbnails and watching the reps freak out when someone pushed inward on the tubing to see it flex. I was just a customer so I didn't get to touch it, but all I could think of is what would happen if I dropped it while riding one of the local fire/mining roads/trails and dinged it hard on that tubing. I still want one someday regardless of my sanity.
