Can you help to identify these frames, bikes or parts?

ok, interesting. I am thinking/hoping there is some Holdsworth link and with the windows could be RT. If 70's would fit the catalog description and number could be early post shop number system ~1976. Who know's, I thinks its too good to go unbadged.

If you can identify this accurately enough to want Thame decals, I have some in white from the early 80s that you are welcome to. To be honest, I am no fan as has been detailed elsewhere, but the seat cluster and rear ends do look like Thame, or at least the work of someone else that he would sticker as his own.

ok, thanks. I have some from H Lloyd read to go on if needed.

Still trying to confirm. It seems similar to the catalog for the 70's bikes, but looks more 80's to me with the recessed bolt and no rear brace. That said I have been informed this could be missing on some TT frames. Maybe it is a latter frame as I understood they built to order after that. I also can't place such a short number.

Has this been 'moved on'? Quite a mix of part on the bike, if he broke it up in pieces I'd take those Galli DT shifters.

Cheers

Interesting searches, I see what you mean about Mike Kowal's, very similar seat stay attachment, but didn't see any windows in any lugs. The Aende's had some windows, but the stay attachment never matched. Not much to see on Dave Moulton. They all had many with missing stay brace. Also found a RT with missing brace on a shop numbered TT frame from 1975.

Been looking at the brake boss again, I assume these were available to all, but I have two other frames, A 1980 Holdsworth Pro SL and a 90's Falcon CB Criterium with exactly the same one. I am thinking this is suggesting an 80's frame. Can't get away from those windows suggesting a RT. Could just be some sort of sprint/path road single speed build built to customer request. I understand there were no set models in the 80's.

Frustrating isn't it, I have a couple of frames in the garage of unknown origin. One is badged as a Rory O'brien but it's not lol. If my Carhall didn't have the remnants of its decals I wouldn't have a clue.

Roy Thame often tried to do Italian, the seat stays are leaning that way on your frame.

Yes, I'am inclined to agree. Most of the features tick the RT box, nut that number is very low. That said he seems to have used many number systems. It cam with 80's Holdsworth decals which could also fit. Thinking just some road sprint.

I think the most long winded ID I had to do was on a Tom Board Lo-Pro, but patients paid off and I got to speak to him some time ago and he confirmed it.

Whilst thinking about any Falcon connection, Andy Thompson was employed to close Falcon down, whilst doing so he unearthed a pile of frames. AFAIK they were columbus Italian road frames and not track frames. I guess yours has a normal 68 mm BB.

The idiosyncratic nature of lo-pros must be a nightmare to ID , thank goodness they were before my time :)

Yes, this is a 68mm BB. I am relatively happy to leave it a bit vague. I am reasonable convinced it it RT not least because any other leads go nowhere. I think the 70,s catalog all show normal bolted rear caliper. So again looks like 80's. I have not seen a RT cat for the 80's and believe it was more bespoke by then. I'll leave a bit of a question mark on this one and see if anything else turns up, in mean time I'll put RT decals on.

Fortunately the lo-pro has a very distinctive seat stay attachment which Tom identified as one of his. There are several similar ones, but the small pad was the give away.

Nice :). I've got a Chronometro badged as a Roy Thame, that took a bit of untangling :)

Roy Thame and Holdsworth are totally interchangeable, they were produced by the same builders.

Yes, i remember the discussions on that one, and often see RT badged as Holdsworths. I have been looking back over the shop built holdsworths and the RT ones in 74/75 invariably have windows in the lugs and often short seat stay caps. We do see RT with 69xxx numbers and one of those has windows, but as the sequential part is high it could well be from early 70's as per the discussions around yours. I am coming to the view that typically Holdsworth did not use windows except late Pro.s, they also tended to use std. stay caps with the fastback exceptions on TT style frames.

Looks like RT continued building his own frames after 75 when Holdsworth went to the 6D system from the factory. Roy's seems to be using 5 or possibly 6 digits some with letters and built from the shop using the frames builders of the day as mentioned above. We did have some odd frames not able to be identified which I initially put in the Falcon Holdsworth group due to the letters and high numbers. But now I am inclined to think they too are part of the RT group as they also have windows. This leaves the Falcons without windows and std. stay attachment all built in 531C tubing as far as I can see. Moving these odd frames gets them into the right time period and cleans up the other groups nicely.

With this frame here I think the seat stays are similar to the description of the RT Cometizione which is the only one in the catalog to have the stays mentioned, the other bikes have more commonly seen attachments. Also the Holdworth 531 Special has a similar attachment and is a bit of a one off. The windows are the same as RT used on later frames and the general geometry is the same as my other 69xxx shop Sprint, only the angle could be one deg steeper as the RT Comp. I don't think the 70's catalog shows recess brake bolts so think this frame is later than the 70's, but still likely to be a RT?. The only remaining question is the short number? I can only assume it comes from shortly after some reset and the options for that would be 1976 or 1984 when Marlboro bought the factory and the shop was stand alone. I am therefore more inclined to go with 80's particularly as it came badged with a Holdsworth decal of the period. I've not found a 80's RT catalog, but believe things were more bespoke customer build at that time..

Bit long winded, but running out of other option to follow.

Hi, sorry it's been moved on complete.

Hello, I need help with cannondale frame identification...
it is strange to me that frame has head tube like caad 5/6/7/8optimo, rear dropouts like caad 3, straight seatstays and front triangle with cable routing like caad 3/4/5. Rear dropouts with rd hanger are the most intresting things to me

Anyone able to help me identify this? It has columbus dropouts

Maybe strip the rattle can paint job and see if the original paint and decals are still underneath?

Forks I suspect are not original to the frame, could be wrong though.

Yeah I was thinking of stripping the paint, but stripping the paint will mean all of the layers. Unless there is a way to just get rid of one layer.

Yeah @coventry_eagle I think the forks are in too good condition to be original.

A friend sent me pictures of his bike but has no idea of the history or frame builder, anyone have any clues as to who it could be made by? The guy who gave him the bike said it might have been a replica of a TDF winning bike

P.s. sorry for no drive side photos, have asked for them but friend has not delivered

A few more pictures, no serial number under BB, finishing kit is Dura ace (1st gen?) And 531 tubing sticker. So im thinking it was a custom replica of a different bike maybe like the previous owner said. Any one know the bike it might be modelled on? From the Dura ace, I'm guessing it was built up some time in the 70s

Could be a Holdsworth / Mercian / 70’s British builder with those lug details, cable guides and I’ve Dave Yates that has that seat tube cluster but that’s later. Drilled dropouts are nice. Really nice. Well worth a good clean up.

Edit. If your friend was happy to drop the fork out, there might be a serial number stamped on there which might help.

I think the lug work, with those windows, and the style of TT cable eyes are wrong for a holdsworth. Very few models had windows. Can't see any frame number on the picture, can you get a better view. from 1976 Holdsworth change from 5 digits to 6 and the location moved to typically to further up the drive side of the BB.
