About to buy my first road bike. I keep things for a long time, so won't be upgrading the frame in 2 years. I will ride 2-3 time weekly, 15-40 miles each time. I'm deciding among three options:
Cheapest: Diamondback Century 2 for $800. http://www.diamondback.com/bikes-pavement-road-endurance-road-century-2. To be purchased online.
Mid-range: Trek 1.5 2013 for $1000. www.trekbikes.com/us/en/bikes/2013/archive/trek/2013_1_5_h2_compact/ Ridden and comfy but not real zippy.
Higher end (for me): Cannondale Synapse Tiagra or 105 5 ~1200-1400. Comes with a professional fit.
The Diamondback is tempting, given the 105 components and the price, but it's got some no-name hubs and non-105 brakes. Is that worrisome? Any other thoughts on these options?
