I believe I have truly lucked out with a WalMart Special. This is a Kent GMC Denali. I have well over 2000 miles on her, and have had only minor issues. The bottom bracket is now a sealed unit, and I have a 52/36 that I normally use. Since it's been 4 years since I was serious, I put the original triple back on... for now. Other than the BB and the seat, I've not had to change a thing. Like I said... I lucked out. I'm going to get the hubs serviced as soon as I can. Given my goal of 3 sprint tri races this year, the plan was to upgrade as long as I PR'd 2 of them... We shall see what happens. I probably won't ever drop this ride completely because of the sentimental value attached.
