It Never Gets Old ...

This is my fifth season with this bike, and I still get off it after a 30- or 40-mile ride, and think 'What a great bike this is ...!'. I've logged 4,768 miles with just annual tune-ups at the local bike shop. All it has needed was a new set of tires (It has Specialized Infinity Flak Jackets). Excellent quality that has held up well. I was caught in a downpour on one ride and I can't overemphasize how well the hydraulic disks worked in those conditions. I'm 72 yo and I can climb anything with the 24-speed groupset. A solid value, and my next bike will be another Specialized.

Sweet Bike

I use this bike for occasional riding but plan on using it more when the weather warms up and do a few big rides. I've done 26.5 miles on this bike and it was very comfortable the whole ride. Only thing I recommend is changing out the pedals for some clip ins or some all aluminum with straps. Also I'd add some bar ends for different hand positions. The grips on this bike are very comfortable but on long rides the bar ends may help.
