Hi folks

i have an old austro daimler, with an austrian size threaded fork tube. (26mm)

anyone know where i can find an austrian sized headset to fit my bike, as its the last piece in the puzzle to getting it back together an on the road.

i've checked www.ebay.at (austria) but can't seem to see one on there.

any ideas as to where i could buy one would be awesome

many thanks

matt

That 26.00 mm ? how accurate is your measurement ?
I suspect its 25.4 mm with an 0.6mm error..

All else take bike to a shop, have them
Re thread the steerer column on the fork, and have the frame's
headtube machined to a common standard.
a Professional shop will have frame prep tools

Many High end steel frames from Italian builders expected seller to do the final prep
and as aresult the tools were common in retail sellers.

you may try the facebook group russian trackbike.
the bikes made in ussr, like start shosse and takhion, use the same steerertube size and the headset size, the astro size.
the admin seems to have spare headsets.

My Vent Noir was standard 1" threaded. Never heard of an Austrian headset, FWIW...

My Sutherlands Manual lists an Austrian headset standard with the same 26mm steerer thread diameter. Most likely found on the mid to entry level bikes, like Raleigh used 26TPI on the common stuff and 24TPI on the better stuff.

No please don't do this. The threaded portion of the steerer is already one of the weaker parts of a bike frame. To remove what is about 20% of the steerer's wall thickness is going in the wrong direction. Then there's the issue of the thread pitch being 1mm per thread (instead of 24TPI). That difference becomes more and more a problem for good thread form, after running a die over the fork, the longer the threading is. And a fork has a long threaded length.

And if you should do this please make sure that the stem's wedge (please don't use a conical wedge in a slotted stem) is inserted into the steerer far enough to clear the threaded portion. Andy

Different crown race and pressed fitting diameters, as well:

Well, I stand corrected.

Unfortunately, can't help with the question but roughly 30 -35 years ago our family bought an Austro Daimler & a Panasonic - the thing I remember most was how heavy that Daimler was - it had two rings and maybe 5 or 8 rear cogs .

I'm thinking since 2010 the OP figured something out.

And doing stupid and possibly dangerous stuff to a fork is timeless. Andy
