Howdy,

The recent talk about butted Columbus Aelle tubing has got me wondering about my '84 Cilo here. It was built with Aelle tubing (lugged), fitted with a Shimano 600ex 6207 friction non-aero group throughout except for seatpost and stem, Gipiemme dropouts and fork ends, and brazed-on top tube brake cable guides. I've looked through the archives and found no exact specifications on tube ID/OD and seatpost size for the butted vs. straight gauge tubing.

By my best measurement with a well-used, non-digital caliper, the seat tube OD seems to be 28.6mm and it takes a 26.2mm post (post is stamped 26.2). Would this be normal for the straight gauge tubeset or could it possibly be the butted version? I have read that straight gauge Aelle has been spec'd to a 26.8mm seatpost, but I have no first-hand knowledge of this.

The original decal featured an "A" with extended legs, gold background. Due its location in the typical repair stand clamping area, it was damaged when I got the bike. I replaced it but there are certain details of the replacement decal that are different (the "A" lost its legs). Here are the photos:

At any rate, if anyone out there cares to send me the year/make/group, seat tube OD, decal type and seatpost size off-list, I'll compile a range and post it to the list in a week. Just a thought, but I figured it would streamline the archive purposes a bit. 

Looking forward to your thoughts.
