  • i know about it,i was talking about a frame with 130mm spacing and rd hanger(horizontal dropout).Fixed on 130 hub is easy..

  • A bunch of TT frames would work. Planet X did one.

    Edit: https://www.planetx.co.uk/i/q/FRPXPCTTFF/planet-x-stealth-pro-carbon-time-trial-frameset

    It should be 130mm but I'd double check.

  • Or any old road frame from when they had forward facing dropouts

  • tt frame is not very fitting for drops,i was looking for something like a dolan pc but in 130mm spacing(track spacing is uselessss)

  • but in 130mm spacing(track spacing is uselessss)

    Eh?

  • looking for a track-ish frame with horizontal dropouts and 130mm rear spacing,running fixed is not an issue

  • I'm pretty sure they understand. Probably more confused about what your reasons for thinking track spacing is useless.

  • is not really necessary,mostly limitating..you can have a front disc hub converted to rear with spacing at will,so is that

  • Using 120mm makes life simple for getting an acceptable chain line.

  • sure,see all the "chainline combo's threads " :)

  • I have a pompino that's been replaced to 130mm at the back. Probably fine with most steel frames.

  • Using 120mm makes life simple for getting an acceptable chain line

    Balls. Pretty much any track hub can take a 5mm spacer each side and become a 130mm OLN hub, and it doesn't change to the chainline.

  • Yeah I don’t get why you’d be against a 120mm spaced frame?

    Chances are you’re gonna end up running the same chainline on a 130mm frame as you would on a 120mm one, just on the 130mm frame you’ll have some extra spacers on the rear axle, have to make sure you get a hub with a long enough axle to get proper engagement of the nuts and the chainstay design might limit the size of chainring you can run.

    I’d understand if you already had some parts you want to use and they would work best on a 130mm frame but it doesn’t really sound like that and generally I’d have thought people do 130mm fixed because they have say, a tt frame they want to use fixed. Seems odd to be actively seeking out 130mm spacing.

  • Seems odd to be actively seeking out 130mm spacing.

    There's such thing as a road/tarck frame?so one could ride fixed-geared?

    He/She is looking for a geared frame that can be ran fixed. 130 can be either, 120 is fixed only.

  • I dunno about Pretty much any....

    The novatec hubs we have on the precursors at work have the axle ends flush or even slightly recessed into the nut at 120mm. With 5mm spacer on each side I’d be worried about how much thread was engaging in the nut. And it’s not like PC track ends are overly thick.

    Similarly, I have a DT Swiss track hub on my Pomp and even on those thin steel track ends the axle is pretty much flush with the end of the nut.

    That said, I probably tell someone everyday I’m at work that their axles need trimmed because they are protruding beyond the nut so there are definitely plenty of hubs with aches king enough for spacing out but also plenty that won’t take it.

  • Ah ok, my bad.

    Well in that case I remember an Isaac frame I think it was that had swappable dropouts so you run it geared or fixed but the geometry was terrible for fixed gear use. It came into the velodrome and the pedals were almost hitting the banking in the straights!

  • Sorry abou the confusion.
    I run a 12mm disc hub as fixed rear,that allows me any chainline/spacing.
    I am looking for a frame to be used either fixed/geared,basically a track frame spaced at 130mm,rd hanger,cage bosses and cable stops...

  • That is the issue..not keen on a conversion,really want track/crit geo with high bb

  • Cool.

    As @bjf suggests then, there'll be loads of tt frames that fit the bill but they might be a bit aggressive for road use.

    Did Kinesis make something a few years ago? Seem to remember a colleague of mine having one...

    Yup, Kinesis Decade Convert.

  • Yep - Decade 2Convert

    It's more an urban singlespeed than a tracksled though.

  • There are several frames with sliding dropouts etc that you can run fixed or geared but you're not gonna get track geo with gears. But then why do you want track geometry unless you're riding on the track? And if you are, I doubt they'll let you on with a mech hanger and cable stops

    Best bet would be custom but I'm guessing thats above budget

    Or modular dropouts with bolt on track ends or gear hanger

  • You could have either of those added to an existing frame for ~100 quid though

  • It's more an urban singlespeed than a tracksled though.

    I remember there being some problems with the track ends too, like they were really short or the attachment bolts got in the way a bit so you didn't get much adjustment or something.

    I'd guess you'd want to check the geometry too, if it was really designed as a road bike and the fixed convertability was added as an afterthought then bb height might be a bit low.

  • Beaten to the geo comment by @PhilDAS.

  • What about a Surly Croscheck?
