thanks both of you. my basic intention was to run it SS for now but have the hanger on as i'm doing some braze-ons anyway. if i was to run it geared, i would respace it to 130. right now, i guess my main concern is getting a thin rear hub in there.
although thinking out loud, i could just use a 130 rear wheel with freehub and a single sprocket...
do road disc hubs come in 130mm? no i guess.
ah yes, I forgot about the extra 5mm of disc hub width. That might be pushing it a little too far.
so we agree that this whole idea is a bit silly
i'm spending a grand on a welder to eke another year out of ten-year-old £99 frame
Novatec do a couple of 130mm disc hubs (24 or 28h drilling only): XD622SB/A-QR-AA-ABG-11S-130 and D722SB/A-QR-ABG-11S
Nice find. It looks like it has the same disc/chainline spacing as the fixie-inc one you linked to earlier, but with shorter endcaps. It would need a change of the axle plus other endcaps to work.
The fixie-inc one would need (I haven't actually tried one) some spacers behind the rotor to fix the disc-line.
Maybe the cheapest/easiest way is to buy a rear double sided track hub and use a adapter on the disc side. This also gives you the option of lockring threading for fixed drive.
There is also a couple of options of using a short freehub and putting it on a normal spacing hub shell from the same brand. 135mm -> 120-122mm, but all need a bit of modification to work.
that last option is extremely attractive, because the bike currently has a rear fixed/fixed hub anyway. i had no idea those disc adapters existed. thanks!
The Fixie-inc also has fixed threading in the description. It is hard to tell from the photo
This adapter is better built than the one above: 6 bolt disc adapter
You probably also need some rotor spacers as well
Magic, ta. i'm sure o could google this, but what is the standard disc line, or is it different for different brakes?
on 135mm hubs there should be about 15.25mm from the dropout to the disc mounting shoulder. This varies a little between different makes of hubs. I am guessing this distance is the same for the 116mm trial hub.
The 6 bolt adapter is 7mm thick so it will sit at 17-18mm screwed on to a track hub (also a guess)
I.S. brake mounting holes are flush with the rear dropout (0mm)
Before you weld anything, you should check if the chainstay and seatstay have enough room for a rotor.
don't worry, i'm not welding i'm tig brazing, so i can safely ignore that advice ;)
seriously, this input is very helpful though.
ahh ok :)
