Used median is 33% of $2,029 new retail — a 67% used-market discount.

Median reflects complete groupsets only. Individual components (shifters, derailleurs, crankset, brake calipers) sold separately are excluded — including them would drag the median down toward partial-bundle prices. See the listings below for both.
