About three years ago I bought a Denali just to have a bike since at the time my Schwinn World Sport was down for refurbishing. I have since gotten my Schwinn back online and the Denali is a backup. I actually have been riding it all this past week as my Schwinn had a flat and I didn't feel like fixing it. Also over the past three years I have actually put approximately 5 thousand miles on the Denali with no issues other than broken spokes on the rear rim. Anyway for a cheap bike with a cheap stamped metal rear derailluer, it functions pretty well. It is an aluminum bike but it is a heavy bike weighing in at around 30 lbs! I also have a Trek 820 that I bought cheap but have not done the work on it to get it roadworthy. Anyway as stated the 820 is a MTB with straight bars and the Denali is a road bike with drop bars. You need to decide which you would be more comfortable on. I want to say this though. How old is the Denali? I ask because 150 sounds kind of high to me for a used Denali. I paid 170.00 delivered from WalMart.com three years ago and I was looking the other day at the website to see how much they are now because I have seen a few on Craigs list for almost 400.00! They sell for 170.00 so with tax and free shipping you can get a brand new one for 180.00! If you can assemble it yourself I would look at just buying new!

Good luck with whatever you decide
