I don’t know if this counts but anyway…
I bought a 2006 Trek Top Fuel 110 carbon ( remember those?) £4k’s worth at the time.
Since then it has had:
Three new frames- to a 2008 Top Fuel 9.8 when the first broke, then a 2009 Top Fuel 9.9SL when the 9.8 broke, and when that one also broke three months laterit became a litespeed Kitsuma frame 🙂 (Trek carbon and I didn’t seem to get on very well)
I have upgraded the brakes from XTR M960 STI’s to XT M785 ( believe me that’s an upgrade)
I have upgraded the rear mech from XTR M960 RapidRise to a conventional M970
I have upgraded to a Dropper post
I have upgraded the forks from Fox F80 to Rockshox Reba 120 RLT
I have upgraded the bars from Richey Carbon 660 mm wide to Easton Haven 711’s
I dare not think how much that lot cost over the last 8 years of my long term test
The wheels are the same, so is the saddle and the nice Trek chainstay protector. Oh, and the seat clamp
Edit:
It is still a fantastic bike
