> What hardware are you using to keep the noodle from passing through? Just the soft aluminum nubbin at the end of the noodle. I pulled it off, put it in a drill and filed/sanded it down to be narrow enough on the OD to fit (this hanger had an M6 threaded hole), then trimmed the noodle tube...

No, I haven't but I could. What would I be looking for?

Also detail shot of the custom brake hanger noodle I made, because I was quite pleased with how it turned out. The noodle started life in a bag of 10 for a dollar I got from AliExpress years ago, but with some cutting and sanding and polishing it looks pretty trick.

The crank crack is strange. It kind of looks like there was some carelessly finished machining where the arm meets the spider, creating a sharp angle and a stress riser: I'm only 165lbs/75kg and I'm not hucking this bike, and the crack doesn't extend to the center, so I'm taking a chance on...

For me it was a choice between dark red and dark blue... I'm not sure if I would have gone for the pink, I feel like by 1993 grunge was in and the late-80s neon color fad was over... Looking back now though I do like the neon pink and blue a lot.

One minor tragedy during the build… the rubber XT brake lever hoods were in near perfect condition until 2 days ago, when something I was using (I suspect maybe the Pledge polish I was using to shine up the parts) contacted some areas of them and turned those areas into basically sticky black...

Pretty pleased to have finished (almost..) my first actual vintage build. I've been interested in early 90's MTBs since pretty much when they were current, and have been lurking here for ages, but this is my first actual build. Story of the bike is a bit random, I never was particularly into...

Ooh, nice. I agonized over (spending my life savings on) this bike vs the Tange Prestige Specialized Stumpjumper back in 1993 (also at the age of 13...). I eventually went with the Stumpjumper but I still have the full specs of both bikes memorized, and I'm sure I'd have been just as happy with...

My understanding is that there are no moving parts. The sensor is a coil of wire that passes through the changing magnetic field from the excitor ring, which generates a changing electric current in the coil, and this is what the computer detects and figures out your speed from. Seems overly...

Final attempt, with new magnet orientation. Absolutely no difference. I'm coming to the conclusion that the problem was never the magnet ring, but the computer itself. Calibration doesn't help either, as the range of available wheel diameters is pretty narrow.

Interesting (and disappointing) to hear. There was a time when these were everywhere though, so they're kind of iconic (at least to me) and I always wanted one. My old Specialized SpeedZone from the same era is still going strong - I think that was made in Japan by Cateye though, unlike the US...

Hah, that's how I got this one (well, I offered $5 to take it off a bike at a garage sale, and the seller accepted) I've now spent $12 on batteries, $18 on the magnetic field film, and several hours on CAD and 3D printing :P It's a hobby, I tell myself.

I'm going to try one more time with fewer magnets in a different orientation, before giving up

Well, I tried... remagnetizing the original ring seemed to be ineffective, so I designed and 3d printed a new ring with 10 neodymium magnets, opposing each other to try to replicate 20 poles... the magnetic field viewing film shows the original and the new ring. Unfortunately, it has exactly...

The 1991 Paramount PDG restoration is coming along. I decided to replace the cables with new stuff with orange housing to match the orange spatter/highlights on the frame. Just basic Jagwire OEM quality stuff, my guess was that this would be comparable to cable from days of yore. I do realize...
