Today was the day we've all been waiting for, 60+ degrees and sunny in NYC. This was my second commute of the year. It was the first on my diy upgraded bike, with a new dynamo wheel, new light, new 10sp XT drivetrain, XT v-brakes (no discs, frame won't take them), Gatorskin tires. It rides like a completely different bike. I spent almost $500 on everything and I'm beginning to think it was worth it. It would cost a lot more to buy a new bike with the same level of components, and a good half of what I spent was on the dynamo setup.
