This purchase will put my parts tally under $80. Including my tools tally puts me just over $100 for the cost of a DIY bike makeover. I need a pedal wrench to change out my pedals since nothing else I have is strong enough or small enough to fit. I couldn't bring myself to pay $20 for 15mm wrench that's a piece of flat stamped steel with a rubber handle. I might buy one online or just look for a thin 15mm wrench.
As for the choice of gear ratio, my finger was searching for the nonexistent shift lever right about 16-18mph. That's not fast enough for me, so I'm upgrading from a 34 tooth chain ring to something a little bigger..maybe something like 36-38. Going with 39 would make it more of a standard size. Apparently, my Alivio 5-arm crank was not a popular setup and hasn't been sold since the mid 90's. It was suggested that I upgrade the crank for $25, then buy the appropriate chain ring for it for an additional $15, but I'm going to cheap out on this and run with what I have. Though including tools, I went over $100, I want to keep the parts budget under that.
Also of note, I have a coworker who is considering buying a new bike this weekend. He doesn't really know what he wants, so I'm curious to see what the Mad Duck people sell him.
