upgrading Derailleur's on a trek 1.0 8 speed
I'm pretty much still a novice here so please bear with me. I have a trek 1.0 eight speed, triple crank, with a shimano 2203 front derailleur and a shimano tiagra rear derailleur. I want to up grade both but most of what I'm finding is made for 9 and 10 speeds. will a Ultegra-FD 6503 work for the front? Seems only difference is it is for a 9 speed chain. I think it should. I'm still looking for a solution for my rear derailleur. Any more ideas on upgrading a bike of this type would be appreciated.
