Thanks all for the info. I believe this is actually an Alex DM24, not a DM18.
I am going to try to find a local wheel builder that can take this wheel apart and rebuild it with a Shimano dynamo - that way I don't have another set of wheels (or a spart front wheel) lying around as Josh mentions. I cleaned up the wheel and there is some discoloration/oxidation around some of the spoke holes - doesn't look like a real crack. Anybody know of a wheel builder in Southern California (LA/OC)? Golden Saddle closed. Thank you. On Mon, Feb 26, 2024 at 8:22 AM tio ryan <rdor...@gmail.com> wrote: > I appreciate that info, Josh!
