Help with frame related questions

Thanks Dave, much appreciated. Its made it as far as the west end of Newcastle so I'm happy to keep in in the North East.

Trying very hard to not buy this... Shed any light on this Dave?

Sorry, without a frame number and size it is just another frame. If you can get said details I can help with  date and other limited details. I might have the original order form but unlikely as most of them were lost in a flood when we moved from Wallsend

[D.A.L.E.]

Fair. I was just looking for any clue as to what it was/when it was from. I can make out Machine on the top tube and that's about it. Will update if I buy it. Cheers.

is it possible to change the steerer tube on some forks from 1 inch to 1 1/8 inch? or is that not good for the forks' longevity? Saw some 853 touring forks that I was thinking of maybe using on a bike frame. thanks

Impossible.  You'd need a new crown with a 1 1/8" steerer socket, so you'd be rebuilding the entire fork.

[fwevans]

Ok thank you for telling. Learnt something new, though now I look at it, it is simple

[rogerzilla]

There are reducing rings that allow you to use a 1" fork in a 1 1/8" head tube but there's little point; a 1 1/8" fork is stiffer where it matters.  Most 1 1/8" forks are threadless and most 1" forks are threaded, just to throw in an extra complication.

Quill stems look nice, and most of my bikes have them, but a threadless setup is technically much better and you can really feel the extra stiffness.  A quill stem is only attached at its very bottom and moves a lot during riding.  You can tell this from the way a freshly fitted quill stem pumps grease out of the headset top nut!

Any idea of the frame manufacturer that puts the serial number on the seat post part of the frame and the number start with NG.

The frame has a Raleigh head badge.

EDIT: It is a nottingham built 1974 raleigh. From here https://www.jaysmarine.com/TH_raleigh_serials.html

Does anyone know about the Joe Waugh M Steel bicycle frame numbering?

Bought this and people have mentioned that it looks very like an M steel build bike.

The frame number starts with mf, so is it an M steel bike, is there anyway I can tell?

Hj Dave , are you still there?  Am I right in thinking you built Pearson frames?  If so I have one, 22" 531 ST , 120 spacing at the rear, cantilevers, no upper rack mounts, no fork mounts, I'm thinking late 70's.Untitled by mark tilley, on Flickr

I think that says 1713
The cantilever bosses appear to be cubes rather than post where they attached. One of yours?

Hi Mark

Just found this, I sometimes get notifications about posts but in this instance not !
Alas, not one of ours. 1713 was an Audax frame built late Jan  1986 which was long before we started building for Pearsons. All the components of the frame look fairly generic for the late 70s there were a few builders turning out stuff like this around that time

[Blodwyn Pig]

Ok thanks Dave, out of interest, how does 1713 relate to late Jan ‘86 ?
