    Can anyone identify this E-stay frame?

    I bought it bankrupt stock with no name. It had a 1╝" fork if that helps.

    (The belt drive conversion is something I did and is not stock)

    How do you tension the belt, without EBB or sliding drop-outs?

    Serial numbers on the frame????? Anything else embossed/stamped?

    It may be hard to know. The elevated stay was "a thing" for a few years and the sport was big enough there was plenty of OEM builders at the time.

    A bit of old fashioned cunning bodging.

    First calculate what combination of front and rear cogs and belt length will get close to you actual chainstay length (within 1-2mm).

    Then carefully peen the edge of the dropout to extend it to the right length and file the other edge to get back to the proper dropout size. Some heat may be required. This of course only works if you can get a close match in the first place. Great for making folk scratch their heads though.

    Thanks. I've been looking at all the photos I can find, and the detail seems to match*.

    I'd better treat it with more respect then.

    But if anyone has other ideas, let me know.


    *except the seat clamp - looks built in on the pics I've seen.

    Yup, British Eagle Boss or another manufacturer using that Far East frame like Aquila. It's not a Mammoth as it's missing a number of the finer details like the internal cable routing running on the downtube or the pulley operated rear brake (and you certainly wouldn't have been lucky enough to buy a Mammoth as bankrupt stock in the UK as they weren't bought in in any numbers)

    Here's a couple of fine examples of yours from Retrobike:

    Thanks, that looks more likely, especially the last photo because the fork looks similar to the one that came with the frame.

    If it's British Eagle I don't really have to worry about destroying a priceless piece of heritage if I do some more modifications.
