Super starter road bike
This is a super value for a starter bike. I'm just getting back into riding after a 20 year lay off. I looked around and couldn't find a road bike at a LBS for under 0. I really wasn't sure if I wanted to spend that much. I found this bike on Amazon and was a little unsure about it until I rode it. This is a great bike for someone like me ( a novice in his 50's). It was easy to assemble and after riding it all doubts disappeared. The only suggestions I have is to get a bike computer, gloves,helmet and a more confortable seat.

Awesome bike
This is a great bike. I am a little over 6ft tall and glad that I got the 63.5cm frame. The bike needed some tuning but a great deal for the price. The STI shifters are really great and the bike rides awesome.

Highly recommended if you are a new road biker!

Sweet Bike!!
5 stars! This bike is great if you are a beginner biker and you want a quality bike without having to pay ridiculous prices for the higher end models. The bike looks amazing and is very enjoyable to ride. Also, it is very easy to assemble. FYI, the shifters don't tell you what gear you are in, so it takes a little practice to get accustomed to the gears.

25" GMC D XL
As to the last reviews, i ordered the 25" model and it came with all shimano components, STI shifter, Tourney rear derailleur and shimano front derailleur. Bike needed a fair amount of tuning on the derailleur and brakes. No shipping damage or missing items. Bike runs great so far. Fit is good, I'm 6'2" and i have around 1 inch clearance from the top tube.

Buyer beware!
The only component that is Shimano on the bike I recieved is the front derallieur. The crankset has no name. The rear derailleur is some cheap brand called micro shift. Assembling and calibrating front and rear derailleurs were not my cup of tea. I had to true my rims cause they were like frys. I called GMC and Ms. Swan from Mad t.v. answered i told her about the components not being Shimano. She said sorry it depends on the time of year. They don't really care. GMC should stick to what they know making cars and not bicycles.
