I've been a bit torn whether or not to, but I'm pretty keen to swap it out for a couple reasons:
Wider gear range - I'm usually in Sheffield so a looot of climbing
-Better braking - again, Hills
-STI shifters - downtube are loovely but just not for me
Fair enough. Modern 105 is a four arm crank though so you won’t be able to swap rings.
I put a modern 10 speed silver Campagnolo Groupset on my Merckx which looked nice. That gorgeous red deserves a silver groupset
