Found all this stuff somehow. It’s been sitting for a while I upgraded that old bike to 10 speed after only 2 years so this stuff probably only had 3000-4000 miles on it before it went into storage.
The tiagra RD was run with the 105 FD after I did a newbie move back then and crosschained and twisted the old tiagra one.
Also found an older Ultegra RD
PM me with your cell I can send more pics.
