Sorry...I was running late to work and had to bail. Having trouble posting my pictures. I'll probably stick with 26" although I will look into 650c as a possibility. Definitely going with cantilever - no disc. I do have the parts to the original headset - steerer is threaded 1" and a bit rusty. New fork is 1 1/8 so will not go on this bike, obviously. (Anyone wanna buy a Ritchey Carbon fork?
Planned on changing out fork/stem/handlebars, etc. with lighter, threadless system. Checked out Wound Up components - might find something there. Thanks for all the help. I will continue researching and eventually post before and after photos - although that will be awhile to be sure.
