I picked this up locally for a steal. It was listed as a Klein carbon because of the fork but am unsure of what brand the frame is. Appears to be titanium or a titanium alloy. Could be an off brand but overall the build quality looks nice. It somewhat resembles a couple of Sandvik frames I could find but the serial number being hand etched is throwing me a little since most I can find are stamped. Any info would be appreciated. I posted it here since it is apparently older and has a 1" steer tube. Does this frame look familiar to anyone? Thanks!

Litespeed Classic perhaps

The dropout joint doesn't look like a TST/Sandvik nor a Litespeed. (I have both)

Agreed. I can't find a similar drop out joint online either. It doesn't look as refined as some of the better know brands, not necessarily "chunky" but definitely not streamlined. Also, maybe it is hard to tell from the pics but the downtube is ovalized.

99% sure it's a Habanero. They were big fans of 1" head tubes longer than anyone else in the titanium biz. I think they're still using dropouts that look like that.

Good call! It looks like their team issue. I am going to email them to see about the serial number.

I have an Airborne Zeppelin Ti, I think 2004, that I purchased used. It has an ovalized downtube, but that is about the only similarity. Dropout, chainstays, serial number, BB area, etc. are totally different, especially the seat and chain stays. Mine has an etched serial number: SER10845. I have tried to find a data base for these with no results. If you, or anyone else, thinks it will help, I can upload more detailed pictures tonight.

My first thought was Habanero as well, but the two that I have had do not have serial numbers. Could have been added by an owner along the way. The welded in bottle bosses is something that Habanero does. Is it a 27.2 seat post?

I am fairly certain it is a Habanero team issue based on the dropout details and the downtube but I emailed them to make sure. I am not sure about the seat post size, the one that came with it was way too small and I haven't tried another one.

Not that this has anything to do with that... but what do you have going on for your mirror?

The mirror is a Mirrorcycle brand. It connects under the hoods of 9 speed Shimano brifters. It works pretty well with not that much vibration. However, the knob that it mounts on snapped off and it is no longer on that bike. I know they are now available for 10 speed and maybe 11 speed. I have another one of the same brand that is for bar end mounting. It is a bit harder to get it focused properly without it being in the way of the hand or blocked by the arm. Also, a bit harder to use visually due to location. I have an old Roadgear that mounts on the hood of brake lever/brifter hoods with a velcro strap that is my favorite mirror. They are no longer made. I did find a couple of them on Ebay but expensive, around $70.

The Mirrycle for old non-aero levers is my ideal mirror- I just haven't found anything quite as good for aero levers.

The closest I've found is an old Axiom mirror.

It would be atypical for a manufacturer to use an engraving tool for a serial number but it would be plausible to reverse engineer it to 1999, which would be consistent with the 6500 series Ultegra components that were introduced for the 1998 model year.

I emailed Habanero and they said it is most likely one of their custom frames. It has a few details that don't match up with the production frames of the era but it has all the signs of their fabricator. I emailed them again about the serial number but I assume they would have numbered their custom frames to differentiate them from the production line. Since they didn't usually number their frames then that might explain the engraving tool and not something stamped.

If it is the Team Classic, you will enjoy the ride immensely. It has been my favorite non-vintage frame to date. Simply rides perfectly.
