13 Vintage Mountain Bike Derailleurs Worth a FORTUNE in 2026 (NEVER Sell These!)

Subscribe:    / @cycleworth   Vintage mountain bike parts are the one honest exception to a rule I repeat constantly on this channel: bikes have no resale value. Frames depreciate. Drivetrains from the golden era of mountain biking do not. In this video we count down 13 vintage mountain bike drivetrains and drivetrain components that are quietly worth serious money in 2026, from Shimano Deore XT M735 and SunTour XC Pro MicroDrive all the way to boxed Shimano XTR M900, where a new old stock group has been listed at nearly 2,800 euros while a used one sells for a couple of hundred. Along the way: Sachs New Success (and how buying Sachs in 1997 turned SRAM into the world's number two component maker), Mavic 845, Campagnolo Euclid and Record OR, Kooka cranks, Grafton Topline, Cook Bros Racing, Bullseye and White Industries. We cover what actually drives vintage MTB component prices (logo variants, boxed condition, completeness), why asking prices on eBay and Retrobike are not the same as sold prices, and which of these I would sell right now rather than hold. If you have a parts bin full of 1990s mountain bike components, watch before you list anything. Vintage MTB values, retro mountain bike parts worth money, Shimano XTR M900 value, SunTour XC Pro value, Campagnolo mountain bike groupset, what old bike parts are worth money. Which is it for you, SunTour or Shimano? And what is in your parts bin? Tell me below, I read every one.
