Specialized Bicycle Components
Was looking at the ROUBIAX SL4 disc with 9 speed SORA group & SL4 Elite disc with 11 speed SRAM but awful colors for 3K.
Shifting to the TARMAC i like this one with the 105 group.
Disc's are nice but its almost like im following the marketing instead of getting the bike [i] want.
What are the differences between the ROUBIAX & TARMAC ?
