|This is a question about frames only.If you put next to each other, what is the difference between:
quantum, quantum pro and quantum race?

|same for '02, except the qpro had the carbon seatstays. For '03 the line-up has changed a bit, as Klein has introduced compacts. The qpro carbon team & qpro carbon frames have the traditional geometry and are identical(both w/the carbon seatstays). Klein has added the "q-carbon" series which are their compact line. This line includes: the q-carbon team, q-carbon race, and q-carbon. All three of these frames are also identical(as far as I know).

|The Q-Pro in years past has tended to use its own headset and sometimes its own bottom bracket.|

|Pro's have a lighter, stiffer fork than the rest. the others have and Icon fork.
I think the only other real diff is the headset...
look at klein's website for details. they keep some old bike spec there

|In past years, Quantum Race and Quantum were identical with different component spec. They had the same frame and fork. Quantum pro had lighter, straight blade fork with integrated headset. Only difference in 2002 was the Q Pro got a carbon seatstay and kept the integrated headset. All three frames also got a newer aluminum alloy. The 2 cheaper frames kept the Icon Air Rail fork with alloy steerer (the same fork that is on Trek frames - it's heavy but performs excellent for the price). 2003 lineup is just plain wierd- Trek/Klein added a whole compact frame line. That's all I know.
I got an unused '99 Klein quantum frameset for $350 last year, built it up with Chorus and weighs 18 lbs. including fairly heavy open pro wheelset. The bike is perfectly capable of competing with almost anything else in an amateur peloton. Best all around frame I have ridden. Light and very stiff. It's rigid but not nearly as bad as other aluminum frames. It's deceptively stable in a straight line - which is nice when you're tired and in a tight group, but not the most "flickable" through tight gaps. However, with the steep angles and high bb, you'll be amazed at the tight corners you can carve when it comes time to lean a little bit. Very honest road feel too, but that also depends on wheels and tires. Also makes an acceptable time trial machine, given the straight line stability and steep seat angle. As I said before, it doesn't excel in any one event, but does darn good in everything. It looks good and is just plain fun to ride, more like a steel frame than Trek carbon or cheap aluminum. I would suggest looking elsewhere if you're a flyweight or doing only long rides.
