I'd recommend the Trek 520 if you can budget for it. It has a track record of durability. The bar end shifters are known to be more reliable than brifters, which my auto-spell utility is fervently trying to change to 'grifters'. There are a lot of other options though. Personally I commute on a slightly modified 2002 Bianchi Volpe. I didn't need the big range so I swapped the Deore RD and 11-30 cassette out for a 105 RD and 12-26 Sram 970. I recently saw the Trek Crossrip series for those who like STI. Jamis has a number of options worth looking at which tend to be leaders at t a price point, such as the Aurora/Aurora Elite for bar end shifter fans, and Bosanova for brifter fans ( I have an early version of Tiagra grifters on my Volpe and they've been pretty trouble-free) Let's see if there are more responses - a great thing about this forum is that people will chime in and make suggestions despite that you did not specify price point, but if you want to get more personalized recommendations, please do suggest budget guidelines.
