Here we have a Vintage, 2000s (Date code BI for 2003) Shimano 105, FD-5504 9 Speed Triple Front Derailleur with 31.8mm Clamp and bottom pull mechanism. The mech is fully functioning and all the adjustment bolts turn freely. It does have some signs of age… some tarnishing of the alloy body, the steel cage is rust free. Overall a fully functioning mech that it will make a nice cheap spare for a vintage bike.
