Specialized Tarmac SL6 Build
It鈥檚 been a while since I last worked on my bike. Recently I decided to route the cables internally on my Roval handlebar for a cleaner look. I attempted the disassembly myself but was overwhelmed by the complexity of managing the two hydraulic hoses and two cable housings from my Shimano 7020 groupset. This sparked the idea to upgrade to a Shimano 8170 groupset. After browsing Canadian bike shops, I discovered that a complete 8170 set costs over $3000, ballooning to nearly $4000 after taxes....
