I'm in the market for a new bike (or possibly a groupo upgrade on my current bike that has 8-speed Ultegra 600 components from the early 90s). I'm trying to determine if the premium for an Ultegra drivetrain is worth it.
I know one of the main differences between Ultegra and 105 is going to be the weight, which I am not as concerned with as much as I am with durability and reliability.
I typically put 150-200 miles a week on my bike with my long rides being 50-100 miles. I am not a serious racer, but I do participate in 3-4 organized race/rides each summer.
If I go with a new bike I'd like to stay in $2k range, but could talk myself into as much as $3k if warranted.
Also, since many builds seem to be coming with mixed components are there any items I want to make sure I don't skimp on? I'm guessing STI levers and derailers specifically?
Any words of wisdom?
