Looking for advice. When I was looking for the best newbie/recreational/commuter groupset, I was recommended 105 is the best in terms of quality/durability/not too expensive.
Now, my left brifter got broken after just 50 kilometres. 105 5703 groupset. But I got it 2nd hand (taken off a new bike, unused, but still 2n hand - no guarantee). Now I need new STI brifters.
Which brifters do you recommend? Are 5700 good and I just got a bad piece? Should I get ultegra? Are Tiagra good and will they work on a 3x10 105 groupset?
