I'm sure there are other Mikkelsen threads here. bamab2's frame does look very nice. Bernie's known for building fast, but that doesn't mean he didn't make 'em pretty. My '82ish Mikkelsen is similar in build details, except mine has fastback "shot-in" stays instead of OP's very lovely wraparound, and my lug points are a little broader/shorter.
I contacted Bernie some years back about mine, which I got used, and had a very nice chat. Bernie hadn't serialed his frame up till that time, I'd assume he still doesn't, but could roughly date mine based on build details. The build cues for OP's/my frame are:
French-finish stay/blade ends: "early '80s"
Cinelli fully-sloping fork crown: "pre-'85"
He couldn't nail it down any tighter than that, and I've been thinking of my frame as '82ish. Looking at it today, and seeing the under-bb cable routing, maybe '84ish is a better guess? Anyhow '80-'84 seems to be the window.
He also said mine was likely Columbus tubing, prob. SP downtube in my 61cm size, .9-.6-.9
He said the seatpost binder bolt was originally 10/32", so don't muck it up with a metric wrench. He also said don't use a stainless bolt if you replace it.
I haven't ridden mine in several years, I oughta get her sorted out and on the road.
Hey pcb. I would like to see some pics of yours. Mine actually has a serial number. I can't make out the first three digits but I sent it in the email to Mr. Mikkelsen. Maybe he can help when he has time.
