    Yeah it would be but they're a lot rarer, more expensive and can't be easily ran as a fixed gear. Plus that would be no fun haha.

    Ok cool, thanks for those standards.

    I suppose a 160mm disc would put the caliper further away from the spokes and seatstay than a 140, as long as there is space in the rear triangle for one. Cool!

    I suppose I need to design a tab to weld on to the chainstay now, that will fit the standards. I think Peter Verdone has some on his website actually.

    Ah yeah, that is a good point. Those disc rotor spacers are a good shout.

    That's interesting about caliper-spoke clearance, I didn't consider that - only seatstay clearance. Your project is pretty interesting!

    I would use MTB calipers instead of flat-mount because I like to ride flat bars, which would change things a bit as they are wider but shorter.

    I think on a 120mm hub disc line does equal chainline, because the hubs pictured above are designed for fixed / fixed use, with a 6-bolt cog (pictured).

    They aren't designed to be used with a disc rotor but I don't see why it wouldn't work, to allow a 120mm frame to run disc brakes.

    That's a really good design actually, cheers. I can't see how it would allow you to move the caliper as you tension the chain though?

    Yeah I would use a hub like that, and run a freewheel on the threaded side with a disc on the ISO fixed cog side (I am talking about using it for singlespeed, not fixed, but with the option to flip the hub over and run it with an ISO cog).

    Surely chainline would be fine as its a thread on freewheel on a regular threaded hub?

    Hi,

    Has anyone ever tried to weld/braze sliding disc brake mounts on to a steel frame with a 120mm rear end, e.g. a Pompino? I'm considering buying the frame and parts I'd need to give it a go, but was wondering if anyone has done it and can give advice.

    Thinking of running an ISO / 6-bolt flip-flop 120mm hub, with a disc rotor screwed to the ISO side, and a freewheel screwed on to the threaded side.

    My reasoning is that I want a bike I can run single-speed when I want to, but I hate caliper and v-brakes, and I'm not a fan of any disc single speeds on the market, plus they are hard to find for cheap 2nd hand and their 135mm rear ends make running them fixed a pain.

    The only issue I can foresee is a chainstay-mounted caliper clearing the seatstay (see attached), as track-ends rule out seatstay mounted calipers since you'd have to remove the brake to take the wheel out.

    Cheers!
