Another thread about mounting disc brakes to a frame...

Notices
Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

I agree with getting a custom. Maybe do one at a time, wife's bike first. Doing this conversion is a pretty radical modification on these bikes and a bit of an experiment. You may find that you don't like the result. At least with the new bikes, it's a known quantity

If this is the case, your current bike might only be 853 in the DT/TT (I'm guessing here but...seems likely).

It looks like the XR is made from 725 which is a similarly high end heat treated tubeset. The XR would be a full upgrade from your current bike including braze-ons, wheel fitment, headtube size and fork. It's any easy choice for me - aside from the $$.

I'm less sure what to tell your wife about the paint! :-) You could have a painter put some accents on it for relatively little $.
The stays on my bike aren't 853. Apart from the colour, the thing that worries me about the Norco is the press-fit bottom bracket.

I have had some discussions with a well known framebuilder who has done a lot of pioneering work with disc on road bikes. He noted that to meet his safety standards, especially the forks he has to build stronger and his disc frames are are heavier. disc vs caliper is all up to planned usage
From what I can see as the cost of a custom frame locally (at the more affordable end) it would be getting toward double the cost to get a custom frame from scratch.

We've pretty much abandoned the idea of modifying my wife's bike as it's not worth it. Might look at other frames such as the Curve GXR steel or maybe a Shand Stoater if she wants a particular colour! Cost wise would still be less than a custom frame. Mine I'll think about for a while. I still enjoy the ride as is, and there's always the risk the modification would stuff it up. Although I do find the lack of braking power for emergency situation a bit of a worry in traffic, particularly now I'm used to disc brakes on the mtb. Perhaps for now I might look at trialling v-brakes with a travel agent and see how that goes.
