28lbs is not super light so it will drag you down uphill but not much. The frame made from aluminium 7005 and you know when you ride on it. Rims are awfull I have warped them twice riding 3.62 miles with minimal bumps. Even with the rim problems the bike seems to be very stable and should last quite awhile. I weigh a slim 240 which I'm sure helped with the rim issue.
Bike comes with a good initial component setup.
No no-name brands. The price won't put a hole in your wallet, and is a good deal. Lightweight alluminum frame. Seat is very firm and will give you sores if you're not accustomed to it. Could have used a suspension seatpost to alleviate this.
