Add popped up close to me. I have first viewing in the morning, its going to be a buy now check later thing. (Its been sold with a load of shimano 600 arabesque stuff so that alone is worth the asking)

However, I've seen this fork boss before and I cannot remember who makes it.


Any ideas?

Thats a fork...JK

True, I cant edit the title though. If it helps the same marking is on the top of the seatstays too.

Henry James? Holland? Hennessy?

I don't think its any of those. It rings a bell though, I've seen it before. Bearing in mind I'm in Ireland, so a Holland would be a rare thing here.

Okay, I picked up the frame plus components. The what I'm presuming it is is an "h" with two lines crossing through it. There is the number "60" engraved on the BB area and on the steerer tube. No other manufacture markings on the frame. Braze ons for water bottles and the downtube shifters. 126mm dropout spacing

A few clues.

Any help. I'm a bit lost on this one

assuming that logo is a stylized "HH" the only name comes to mind is Harry Havnoonian, longtime USA custom builder based in Pennsylvania. This does not look like his work or his HH logo:

Seems more like a European production frame: what threading is the BB?, what size seat post?

Oi! Frankenstein might be looking for that hexbolt on the seatpost clamp!
"60" might denote frame size.
The logo kinda looks like a man holding a stick....

BB threading on the Shimano BB states 36X24T, which I'm guessing is Italian thread BB. So its either, according to sheldon; a high end french frame or an italian one. Sorta fits with the gipemme dropouts.

Seatpost seems to be a 26.2mm seatpost. Though thats measured with a cheap digital calipers so that might be wrong.

Italian BB and coupled with the Gipiemme DOs I'd say it's an Italian...no idea of any brand with that logo, perhaps it's a house-brand. I'd also bet that the seatpost size will be something larger than 26.2, you'll need to go to your LBS or just try a selection of posts until you find a good fit...I'd go to the LBS in case there's some deforming of the seat lug that needs attention. My last guess: it's going to take a 26.8 and that's because it's Aelle tubing.

I have a 26.8 seatpost near to hand and there is no way that fits in, whereas the 26.2 (my calipers flits between 26.1-26.2 when measuring it) fits quite snugly. I don't see any deformation of the seatpost and neither did the my favorite bike mechanic when I went in for a chat about it this morning (though we really weren't looking at the seatpost though at the time)

I'll double check in the morning though for anything funny along the seatpost.

so much for that last guess...I've been wrong before, so I can live with myself
a 26.2 might indicate a pretty thick-walled seat tube (not such a good thing) or perhaps a seat tube brazed in upside-down (with a butted section up), or a metric tube: what's the outside diameter of that tube (and the other 2 main tubes ,too, just for fun)?

26.2mm seatpost sort of indicates thicker tubing than the typical double-butted. Sounds like straight gauge to me. It may not be a very high end frame if that's the case. BTW, I've never seen that mark before, very interesting, almost "Burning Man'esque".

A little bit of an update. I'm going to have to bin that calipers. In the light of day the seatpost says in faint markings under the grease - 26.4. Moral of the story, dont try measure anything with a cheap calipers after a drink

I dunno if its worth using it as it could not tolerate a .2mm difference. I'll have to measure it using a decent calipers. Perhaps i could "borrow" a micrometer from the lab

I however, have a decent scales. The 62cm frame + fork weighed in at 6.86 of your medieval pounds. That sounds light enough to me but I'm not too experienced in C&V bikes.

Its not an ultra high end frame, I'm guessing. 600 groupset with a light enough frame sounds like a decent mid end frame to me. Its worth noting that the wheels are 700c sized, mavic rims with a 600 hubs.

More pieces to the puzzle. The fork is chromed and I presume the entire frame is chromed. I peeled back paint on the top tube and the bottom tube (just a small are though) and there was chrome underneath. I cleaned off the fork with paint stripper and polished it up. The chrome is coming back rather well, although there is a small amount of corrosion on one of the fork blades, but nothing brass wool and polish wont sort out.

^ looks way better! post a photo of the entire bike minus the paint when you get time.

Thanks, I think it looks far better too. I may not know who made it, but it will certainly look good

I suppose you could do better than Mavic rims and 600 hubs, but why would you want to?

I'd recommend against trying to use an 0.2mm undersized seatpost. Maybe the pinch clamp has already been squeezed by someone else using an undersized seatpost, but you'd be better off using the right size. Since the pinch clamp may have been squeezed, you really need a bore gauge to confirm the 26.4 dimension down below the pinch area. If there's grease or crud down there, it might need to be cleaned or even honed beforehand in order to get an accurate measurement. If the clamp area is indeed squeezed, it should be possible to judiciously rehabilitate back to the correct ID.

bumping this cause I read some more about it on the CR list (where our OP went after here) and in case you're wondering...seems that it is a house brand for a German shop called Hacker (with an umlaut over the a).
Zweirad Häcker GmbH, Stuttgart

Straight-gauge tubing, mid-level stuff. 6.86 pounds of avoir du poids is up there. Probably stiffer than all get-out, though....
Sounds like a shop brand, maybe Hacker of Germany?

Remember this thing is fully chromed too so its going to be heavier then a similar frame with paint. Dunno by how much though. It really does not concern me as a stiffer frame would suit me better, I'm 6''4' pushing 200lbs.

A nice set of wheels and it would fly. Its lighter then my all out pannier/fenders touring miyata.
