Ultimundo disc for San Fransisco

Yes, I do make this model for disc brakes even though the version on my website has rim brakes. Times have changed and wireless shifting and flat mount disc brakes are in. I still have about 10 of these True Temper S-3 round top tubes in stock. After that I think I'll have to switch to Platinum tubes which are a bit heavier. I have not weighed this frame yet but it is probably right at 4 lbs.
