This is one heck of a deal. This bike is very light, well built and it seems like it will last for many years. I also had it professionally assembled by Bike Teacher (service provider here on Amazon who services the South Bay Area of California). A couple of notes you should know though: The brake cable in the front came too short from the factory which when tightened made it not very safe and hard to adjust the handlebars. Luckily the service provider was able to extend this for me. Also, the reflectors were not big enough to clasp around the bike... Why they would include reflectors that don't fit the bike is beyond me. Also, plan on upgrading the pedals, seat, and tires. I went with SPD pedals, Planet Bikes ARS saddle and GatorSkin Tires. After reading the reviews, I did not trust the tires that came with it so that was my first upgrade. I am planning to ride this to/from work and will update my review if my impression changes after a while but overall for <$500 on a high end road bike, you just can't beat this deal.

Great program. Like so many of these types or programs it has a long learning curve but I am impressed with the capabilities for the cost.

it is too bad, it is disconnected very often. almost every 2 mins. there is more bluetooth headset with lower price and better quliaty

These fit perfectly, and they are sturdy. No slippage possible. With these in place you can relax. Day after I put them in I spilled a cup of coffee. Easy clean-up!
