Well, I found the men's road bike specs on WalMart.com (which you can buy it a multitude of places):
A steal at this price, Kent's GMC Denali is an affordable road bike featuring components and quality usually only found on bicycles costing hundreds more. A lightweight aluminum frame, high-profile alloy wheels and a 21-speed drive train by the technicians at Shimano are just a few of the standouts in this fast-moving package.
Specifications:
Frame type: Road bike
Frame Materials: Aluminum
Gearing/Shifters: 21-speed Shimano drive train with Revo Twist shifters
Brakes: Alloy brakes
Wheels: High-performance 700x28c (black)
Additional features:
57 cm Aluminum frame is strong, responsive and light
High-profile alloy racing rims for added strength and aerodynamics
Speeds: 21 speed Shimano
Frame: Aluminum frame
Brake type: Alloy brakes
Bike Type: Road Bike
Here are a few things that concern me:
1) Are you able to be FIT on the bike? If the bikes doesn't fit you, then saving money doesn't matter.
2) The Shimano components. Those are so low-end, I haven't even heard of them! Revo? Anyone heard of Revo? Poor components can make for miserable riding... and if you hate riding the bike, then saving so much money won't matter.
3) The weight! WOW! 36 pounds shipped?! The reason why road bikes tend to be faster is because they are lighter. Sure, the woman's bike might weight less... but even at 30 pounds, that is really heavy for a road bike. At that point, you might as well ride your Trek Navigator.
If you could just somehow... find a way... to save up another $300-$400... you could get a much better road bike... new. Can you sell some stuff around the house? Offer to clean some friends houses? Something?
