Braze on disc mounts for Titanium

[Andrew Br]

Another reason to go for a new bike jowwy is that your current machine is probably designed for 130mm OLN hubs while most disc wheels have 135mm hubs.
I'm not an expert on welding but I think the inert gas needed for Ti welding has to displace nitrogen as well as oxygen.

If you do decide to modify your current frame, put the disc mount on the chain-stay; they're already quite strong since they have to resist the pedalling forces and it tucks the brake out of the way.
It still makes more sense to go for a new frame IMO.
Please post pictures when you get it .

FWIW, I own two Ti disc-braked bikes. They were designed that way.

I've considered it and I've seen lots of people discuss it but I don't think I've ever seen anybody actually do it.

decided on a full bike overhaul

getting rid of 29er, changing Ti to a flat bar for commuting duties with rack and guards and then getting a cannondale synapse 105 disc for winter/wet ride duties.

will be doing this over the coming winter and using c2w for the cannondale.......

or i could pay the extra and get the spesh roubaix SL4
