Yeah, the 105 groupset is still a good starting point for decent quality coming from Shimano. I'm primarily a road rider, and I wouldn't think twice about going with 105 components on a mid-level bike. Of course, I prefer Ultegra, Dura Ace or even high-end Campy, but 105 hangs in there pretty well with the best of them. I wouldn't go any cheaper than that, though.Is 105 pretty much the starting point for quality components on a road bike these days? My old bike (1989 Trek 2300) had Ultegra and it was great. Are the lower level groups good quality and performance?
In other words, what is the lowest level of componentry that offers good value and performance?
I don't really plan on becoming a full-time roadie, I just want to be able to ride when the trails are closed, and maybe start commuting once or twice a week (25 miles each way). I work from home now but new boss thinks I should start coming in three days a week. Maybe getting to work sweaty and gross after a 25 mile ride will change her mind about that.
