The Ultegra Groupset is a great quality product, hands down. What is even better than that is the service Texas Cyclesport provides. They bent over backwards to ensure I got everything that I ordered and if it wasn't in stock they swapped it out with something of equal or higher quality. They also ensured I received my online order very quickly. I WILL be looking to them first when I need to add more or upgrade anything on my bike!!!
Awesome group. Super smooth and 34T gives a little extra for the steeps.
