My first commuter bike was a GMC Denali road bike (yes I know it's a POS, but I had reasons for getting it.) I got the Denali so I have something to ride, and I didn't have a lot of cash at the time. My original goal was to replace the components on it, in a piecemeal fashion, and make it a little bit better, especially when it came to the braking. I swapped out the joined drop bars and put a flat bar on it, and tossed the revo shifters, got some break levers and got some half way decent gear shifters. I couldn't do much because I had a very small space and anal retentive building managers. I needed to drill out the holes where the levers went, so I could fit the new brakes which were recessed, but was afraid to on the rear because the hole might of been too big. It got me where I needed to go. I was able to haul groceries on it, and I wouldn't of been too sad if someone stole it, because it was so inexpensive. Long story short, the front derailleur was a mtb derailleur and could of took it to get replaced, but decided against it. I took everything I could of off of the frame and save it as a project bike. That didn't work, because of anal retentive building managers and I couldn't take it with me when I moved.

My second and current bike is a Diamondback Insight II. Not the a top of the line bike but a helluva an upgrade over the Denali (which I regret leaving behind.) Nothing special or outstanding about this bike. It's great to ride, but of course the manufacturer didn't line the front derailleur up properly and the mechanics at the bike fail to notice and told me that I would have to put up with a slight chain rub. I've since fixed that by watching some YouTube videos LOL. I put 700Cx45 wheels on it so they wouldn't sag when my fat rear end was riding it, when it was loaded up with groceries. Though I might put 700cX40's on it instead because there is barely enough clearance in the back to fit the current wheels.
