I have the idea of moving to electronic but the price of a new group set is more than I’m willing to spend. So I thought about used Di2 for my 7 series Speed Concept, but have no idea what to watch out for. Is there wear and tear on certain parts that typically need to be replaced, other than the battery? What would the life expectancy be for an electronic group set?
What do I need to know?
Watch for the rear derailleur pulleys. Could have easily gotten rough without the seller knowing. I ran one with rough pulleys for probably half a year, and it cost me placings.
Rough estimates of pair prices for used parts. Note that parts are getting scarce these days though.
-SW-R671, ~$120
-All wires needed, ~$125
-Internal battery, $75
-EW-90, $60
-JC-41, $25
-FD, $90
-RD, $165
Add $80 for SW-R671, $25 for wires, $75 for battery, $25 for EW-90, $5 for JC-41, $90 for FD, and $60 for RD, if buying new.
