Bike Upgrades

Biking to work saves me a lot of money, I actually save around 5K a month if I do it every day. Also, I help lessen the carbon emissions in the air. But most of the money I save goes to my bike and bike upgrades can be too damn expensive. So, I avoid all the local bike shops in my route.. All 4 of them!!!! It's very tempting to stop and look around those shop, but all I see are mouth-watering parts that will burn a hole in my shallow pocket.

So far here are some parts that I upgraded:

• Hubs
• Rims
• Tires
• Seatpost
  
• Stem

I expect more to come. Do I actually save money? I clearly disagree...
