Ugh, you're right.
From memory, the 18" & 19" models shared the same head tube length and the 20-21" were another size. My LBS wasn't ready to handle the fork switch w/o knowing I had another set of headset bearings but I need to dig that fork out of the garage first and confirm what I have. Remember, my original '93 never had the rigid fork mounted because it came with the Rock Shox instead, so until I know for sure, I'll remain hopeful that perhaps Klein might have messed up my order even more and perhaps sent a fork that will fit the 19" frame I now have.
how long is the steerer tube of your rigid fork? i think the length for a 20" MC1 frame is 120mm. if it is that long, it will not fit your 19" frame because of the elevation for the upper bearing. would be working on a MC2 (you could cut the steerer tube, although the fork rake differs for the different frame sizes). the steerer tubes for MC1 were only the same for 18 and 19", all others were different. i doubt that there was 21" sizing available already to MC1 frames.
