I've been looking at cross/hybrid/comfort bikes in the $400 - 450 range, and I've noticed most have about the same level of components (low-mid level Shimano). If I go up to the $550 price point, the components are typically a couple of levels higher.
I'm going to be riding 10 miles/day (every day weather permitting) as part of my exercise/fitness routine. One side of my brain says go with the cheaper bike now and upgrade the components if/when they need replacing. The other side of my brain says just go for the better components now and be done with it.
What's the best way to sort this out? Will I be able to tell the difference between the components, given my level of riding?
