I am trying to build up a bike from all my spare bits (as you do!!).
I have some shiny 10 speed Tiagra shifters (4600 I think) and most of a SRAM Red group.
1. Can I use a SRAM red front mech with said shifter?
2. SRAM red brakes?
3. Rear derailleur?
I suspect Yes, maybe, no ... but is there someone more knowledgable to infom me please? Don't really want to fit it all and test!
