Hello newbie here.

i have tried to use the search function searching weld+disc / weld+disk etc etc to no avail

I have seen some bikes with disks fitted after market, just wondering if you can buy made up bosses to weld on .

if so where from.

many thanks

Pete

Frame builder is your best bet. You can imagine there can be many variants due to tubing diameter, angles etc and the adapter needs to be fairly close fitting.

Due to thicknes of tube wall you'd need a tig; a mig woould likely blow a hole in the tube. Plus the positioning needs to be reasonably precise within 0.5 mm or better.

Sourced via Paragon Machine Works (in the USA) - matching front and rear calliper mounts :

The rear one is stainless and relieved to save a bit of weight :

Very nicely done to 8) :

The front is solid Ti to suit the forks :

Make your own for the rear , it's just a piece of steel plate shapes with 2 holes in it.
Braze it on and hey presto , bear in mind your frame will need painting afterwards though , if in doubt use someone like Bob Jackson or Ellis Briggs (or a local to you framebuilder ) to put one on for you , will probably cost about £60 > £70 .
