10 years?? LOL. It's impossible to predict where we will be the end of this crazy one.
Go look at all the tour bike photos. These will all be obsolete in 10 years. LOL. DeFAILeurs with crazy dish spokes are NOT the way to go on a heavyweight. Thru axles are NUTS. Pinion is getting popular. Rohloff serial numbers are getting over 300,000 I think.
This summer my custom with Rohloff14 will be ten years old. It's just getting nicely loosened up at 20,500 miles. And I finally got my chains and 1/8" cogs to last way longer.
My first front SA XL-FDD dyno drum brake hub has 32,000 miles, so it has about 6,000 miles left with my other new steel roadster. Already bought the next one. I built a new wheel for the tour bike, good for the rest of my riding days likely. It has Dyad rims and 35c tires, I guess I should have used 38s.
My disc pads went 5,300 miles.
Gravel riding should have 47c tires at least. 559 rims are soon obsolete.
