Its a mystery to me Please Help for my 753 sake

Hi, I am new to this forum and I am seeking help and advice to understand my bike serial number. I have searched the internet for as much info as possible but regards the frame number I am at a complete standstill. I would appreciate any help or even recommendations to further reading. The bike equipment or paint work offer little to identify the bike origin, because prior to my purchase in 1998-2000 the bike was refurbished. So the only clues I have are from the frame.

Okay- The number is stamped to the underside of the bottom bracket 077 xx55.

Other frame distinguishing marks:The frame carries a sticker indicating it to be Reynolds Renovated 753, the tubes are all connected with Cinelli lugs bearing the winged C logo, the seat clamp is I believe termed fast back. There is a square lug with hole attached to the underside of the cross bar. (I am advised this is for a number plate and may suggest a professional rider as opposed to amateur). The bottom bracket has two long cut outs underneath for the front and rear derailleur cables to fit flush with the BB. Two pairs of bottle bosses are also fitted. The frame wheel clearance is about 5mm.

From my research the the gears and brakes are probably newer than the frame, Campagnolo Mirage brake levers, calipers, rear derailleur, Campy veloce front drerailleur, chain set Campy EXA DRIVE, wheels mexico 68.
The handle bar stem is Cenelli, seat post ?? but fits perfectly to the frame, crank Miche.

The frame carries a second sticker indicating "The cycle shop" Phil Sherwood (no longer trading).

The reason for my interest, Well after ten years of ownership I was un-aware :idea: until about a week ago that 753 tubing was such a specialised assembly and had a significant contribution to cycling and has its place in race history, wishing to find out more about this tube has really been fascinating, especially Raleigh and the SBDU and really I would just like to find out did my frame have any part to play.


Once again any assistance would be appreciated

Difficult to help without photos.

A 753 sticker is no indication at all.

Why do you mention the SBDU in this context?

Morning, Roadking, I will attempt to load up some photo's asap once I get back from work. I mentioned SBDU: not that I am implying mine frame is one I was only conveying that I have found that particular subject fascinating and interesting for me to want and understand more about my frame.

Regards the sticker, yes, its possible its only a sticker. That would mean possibly at the time of refurbishment by Phil Sherwood the deception was made, or the purchaser from Sherwoods passed it off to the shop from where I bough it from. The bike shop from which I bought it, was genuine and I assumed the bike is what it says it is.

Once again, any help would be appreciated, Thankyou

No offence meant, happy to help if I can.

Some excellent knoweldge here at Retrobike.

No offence taken, Roadking. All my searches so far have drawn a blank on this serial/code. One theory offered by a friend of a friend is it could have been Raliegh surplus ? and sold off, but I would imagine it would still bear their frame code. My searches for frame builders and their codes other than Raliegh have so far been unsuccessful.

It's got a cinnelli bottom bracket shell, might it actually be a cinnelli that someone has had repainted for racing on? The actual Id I suspect might never appear.

Thank you for having a look Garuf, The frame was repainted and refurbished by Phil Sherwood ?years prior to my purchase 98-2000. The origin of the 753 frame is the mystery, so I am hoping the frame serial number or its construction may offer clues. All of the frame lugs are Cinelli.

From your post you mention it might be a Cinelli frame. Did Cinelli only use Columbus tubing or did they also construct in Reynolds 753. Also would you know if the cut outs in the bottom bracket a usual feature of other custom constructors?

All info at all is good, thank you

Most reasonably modern Cinellis, as far as I know, use Columbus tubes. If it was built by Cinelli themselves it'll most likely have Italian BB threading too.

Hi David B, just back from work and read the post, thank you- I have had a look at the bottom bracket/crank and the crank screwed into the Cinelli bottom bracket is Miche- 1.370x 24BSCR, and 68mm wide, I followed this up and from an old book I have it suggests English thread/ISO.

Sorry to ask another stupid question, if the BB thread is English will that mean the frame with out doubt is English?
