My Giant Sierra beater single speed.

Originally I got this bike for around 20 bucks on Marketplace and then restored it in it's original state but didn't like the feeling of the bike so it sat parted out for a year or so. Then one day I wanted to go to a festival in style with a bike that wouldn't get stolen. So I fished this frame out of the shed built it up as a single speed and rode it like that for a while. It became my vacation bike. It's been to islands. It has been to the mountains in Germany. Then one day while heading to the same festival again the next year I tried to bunny hop a curb and completely broke the rear wheel. I replaced it and rode it for a while until I put new tyres on it. Love the way it rides and feels now with the new tyres. My next upgrade is gonna be v-brakes. Anyone experienced with Avid Speed Dial levers?
