I've had this bike since 1990. She's a bit worn and has had a lot of upgrades but is mostly Shimano 105 (different generations from 1990 -2009) with Tiagra dual levers. She has a custom-made aluminum rear derailleur hanger. The front wheel is original (Shimano 105 hub, Wolber GTX rim) but the rear was upgraded to Shimano) when I fitted the new levers.
