I own a Klein Quantum road bike with serial # 20218. What does that tell me about the age, origination of this bike?

Hi Brett, I may be able to help but I have a few questions. Are there any letters before the serial number? Where was the serial number? (check the bottom bracket and under the read dropouts is there more than one number? Is it a Quantum or a Quantum Pro or a Q-pro? Could you send me a picture of the rear dropouts?

Well, I was distracted by another build for a while. But, I finally got around to ordering some of the parts I will need for the 1994 NOS Klein Quantum II. The replacement outboard bearing bottom bracket from Phil Wood is here along with the Campy Record headset and a shim so that I can use a 1 1/8” stem with the 1” steerer tube. It starts to feel real when the parts begin to arrive!
