OK, so I'll be collecting Heinz (http://yacf.co.uk/forum/index.php?topic=1303.0) from Basil in the next few days, hopefully. I'm looking at the rear and thinking that it is probably a 126 oln given it's a five speed block. Feasibly it could even be a 130 I suppose but it looks too old for that. I know I could just ask Basil to kindly measure it but hey, that sort of takes the fun out of speculating and pontificating :D
Looking at hubs I'm wondering whether a 120 oln will be fine and allow the frame to be 'pinched in', or a 130 maybe with some stretch, or do I need to cold set the frame when I know what hub I'll be using?
Tips and advice from the sages of the board most welcome please.
-
Why not cold set it ? It is easy to do and doesn't take long. Sheldon Brown has the instructions.
-
I've used a 130 hub in a 126 steel frame withou bothering to cold-set it; there's enough sprong in the frame for this not to be a problem unless it's made from some particularly nasty variation on the theme of East Tokyo Metropolitan Water Board Mains Supply (Earthquake-Proof model)
-
I have read Sheldons page. I think I'll be thinking very carefully about that. Cold setting looks easy when Sheldon explains it but he's not come across a ham-fisted brute like me I suspect!
Perhpas I will ask Basil to measure up for me first ...
-
A 126 steel frame will cope with a 120 or 130 hub just fine. The only issue can be clearance of the smallest sprocket on the seat stay with a 130 hub. If you're fixing it, that won't be an issue
It can be a bit fiddle to get the wheel in/out, but it works.
I ran a 135 OLN Pomp with a 130 hub for years, and a 126 Hetchins also with a 130 hub.

It is indeed destined to be a fixie. My curiosity is because I've been scouring the for sales allover thenet and found a few potential rear wheels. Some are 120's and some 130's.
I recall now years ago having a bike that the rar wheel was always a snug fit. I remember after one service I left off a washer from beneath the locknut each side. Hey presto, it slid in a treat! Why they were there I never know. Perhaps it was just factory standard fitment, and manufacturing tolerances were not really bothered about. It was a Raleigh bike from the early eighties!

Yes. Goldtec & Royce do any size you want - they just change the spacers - but nearly all fixed hubs are 120, 130 or 135
You could convert a 126 freewheel hub to a fixed, of course.

I have seen your excellent thread but I'm also finding complete wheels for sale at reasonable prices so I have to consider all my options.

I think so. I'm even thinking it may be 120 after reading Sheldon's pages.

Use a 120 hub and add spacers as necessary. There's certainly no point cold setting a frame smaller. True, pinching in is no problem, but it will irritate you everytime you have to adjust the tension, for the sake of a few spacers.
It also gives you some easy chainline adjustment, should you need to tweak it.

You could build your own - you can get an On-One hub for £15 and a Planet X DN6 rim about the same. Builds into a very nice wheel.

Indeed. And it would be fun in the process.
