Quill stems and 175 crank arms are what I stash. And with two DA7800 machines, I try to keep an extra Shimano DA7800 chain in the bin. IME, nothing else shifts the terrific 7800 group like a 7800 chain.

if only I could source a 7800 chain for my DA7800 bike. Even eBay doesn’t show any. Would the 6600 chain be almost as good?

My lovely DA7800 bike continues to have minor chain clicking, ticking Gremlins with my KMC & Connex chains.

what we really need is ability to archive a digital version of the parts, 'cause one day someone will be able to 3d print you one in the material of your choice.

This.
This is so true! And these digital designs should be made public, not kept secret as intellectual property. Honestly, who's going to make much more than pocket money on reproduction antique bike parts?

Even now, there are a lot of stamped and folded sheet metal things (Nivex derailleur for example) which should be digitized so anybody can get them waterjet- or laser-cut from their material of choice, and make their own. With CNC machining, the possibilities are already near endless. Often the hard part is finding a proper CAD drawing to start with. Getting someone to draw up the part properly can be a huge challenge!

Well for a couple hunnit you can get your very own laser 3d scanner and you can scan and reproduce pretty much whatever bike component you want.

Sturmey Archer stuff pertaining to the British-made four and five speed hubs are getting very rare. The longer 6 1/4” axles and their specific indicators have become as rare as Hen’s teeth. The shifters too, are disappearing. These parts are not interchangeable between even similar models. The Sprinter Five speed control has a different amount of cable pull from the modern five speed shifters, even though they are both single cable actuated hubs. Of course, anyone looking for Stronglight 122mm BCD chain rings (or heaven forbid, Nervar 128 mm BCD chain rings) knows that future proofing these remains a challenge. John Vara’s Red Clover Components does make triplizers and a facsimile of the semi legendary 39 tooth 122 mm BCD chain ring for Stronglight 93 or 105, but the other offerings are dissimilar in profile and in limited supply.

I've got da7800 and was thinking just using a regular hg 10speed chain?

I have a few 6600 Ultegra chains in my stash that I plan to put into use. Hopefully they will run fairly silent with the DA7800 2x10 group.

And now the rainy season has started in NorCal, and then end of DST is imminent, so my C&V bikes will get even less mileage.

And it doesn't take a lot of bikes to get that benefit! For example, most years I ride about 3000 miles. Spread that out between 3 bikes, and it's only about a grand each. So if a cassette or chainring or rim were to last 10,000 miles, that's 10 years of use at least.

That's long enough that I'm in more danger of changing a part to something else before I actually wear it out.

I'm guessing it's far too late to stockpile one inch pitch chains, sprockets and chainrings.

every thing I have seen is there will be no 8100 mechanical. you would need to go down to 105 11 speed for that....which is not shabby by any means, but not what my little OCD mind wants

I think it's critical to acquire skills and tools. They can't take those away from you! I learned to braze, weld, and machine things just about as the SAAB parts and lab stuff really got scarce, so I was able to somewhat seamlessly switch over to making it myself. This is probably what I'll do with bike stuff as well. I've already made a couple quill stems and a front derailleur, along with a smattering of cables and other odds and ends for antique tandems. My dream is to get a shop with all the necessary equipment (CNC mill, lathe, TIG) so I don't need to rely on my workplace for it. I also want space to setup some baths for chroming and anodization. What's next? A foundry, I guess! It would be cool to cast things, at least small stuff in aluminum or bronze.

I figure I should be able to stave off most planned obsolescence this way. As long as bearings remain available, I should be good to go. Making bearings is hard.
Speaking of SAABS 1990original owner red box with lots O parts stashed away.

Bike parts enough to last "my" lifetime.
Best, Ben

I'm mostly worried about wear parts and non-serviceable items. Since my older fleet is MTBs I'm looking for 9 speed XT shifters and cassettes. I also want a SRAM Rival 10 speed group for my wife's road bike because she likes those levers better than 105. I suspect that 10 speed road stuff is getting thinner on the ground.

Wow, I didn't figure Shimano would make such a bold move. I wonder what percentage of sales of Ultegra are for Di2 vs mechanical shifting.

Recessions and other major disruptions give additional cover to discontinue products that aren't the latest and greatest. It will be interesting to see what is -- and isn't -- back in stock next year...

Give the 7901 chain a try if you get a chance. Straight butter with the 7800/7803 drivetrain.

Plenty to choose from on eBay at the moment:
https://www.ebay.com/itm/20360567724...AAAOSwTPNhQUSs
https://www.ebay.com/itm/11502873763...UAAOSwYTFgvHlE
https://www.ebay.com/itm/18504722461...EAAOSwYblhPngj
https://www.ebay.com/itm/27496269335...4AAOSwPFhhUIb3

6600/6700 chains should suit just as well, and are significantly less spendy. As might the HG-95 in a pinch.

7901 chains are the business for any DA 10-spd setup imho, but they'll run you $60 - $100. More if you're in a hurry.

Just based on what I see out on the road I'd be surprised if there was less than 3 Di2 groupsets sold per 1 mechanical in recent months/years. But most of the time I have enough opportunity to hee and haw and others' bikes is in fast group rides and races, and I'd imagine electronic shifting is going to be a little over-represented with those crowds vs. the general populace. I've been on rides where I had the only bike still moving derailleurs with cables out of two or three dozen other riders, my fingers are crossed that Shimano still does continue producing higher-tier mechanical shifters so I can continue to be that guy. I understand if they decide not to though, the market for those parts just doesn't seem to hold a candle to electronic shifters.
