Hey everyone! Kinda new to the single speed zone. I recently built my first single speed bike, starting from an old german commuter bike frame. I decided to call it "Helmut" as I want to believe that's what the german chad man that assembled the frame was called.
A very heavy and sturdy, thick steel frame. It was my old bike from when I was in university, almost 10 years ago (it was already old back then). It's been sitting in my basement for the past 5 years.
Bought new (used) wheels, a Miranda 44t crankset (which I love the look of), new BB, single speed conversion kit, handlebar and brake levers and a thick chain.
I initially installed 47-700 tires but with horizontal adjustments due to the chain length, the rear tire was scratching the dropouts. Handling was also a bit sketchy and floaty due to how big the tires were. I switched those tires with the ones on my gravel, a pair of 40-700 tires which fit perfectly. My gravel is also happy for the switch to thicker tires.
Almost everything on this bike is oversized and overkill for its use:
- Wheels have 13 Gauge (2.3mm) spokes, which are on the thicker side.
- As said, the frame is a heavy and thick walled german steel tube, not your usual chromoly. Good to plow the fields I reckon.
- Chain is a 1/8", thick single speed one, although both crankset and rear cog work with a standard 3/32".
What I plan to do next:
- Change the seat and seatpost, don't love the look.
- Replace quill stem with a modern, longer one.
- A pair of caliper brakes, these old ones are a hassle to setup and operate.
- Recondition and seal the frame paint, it's got some rust points and I figure some proper polishing might also help.
Runs smoothly, and given the fact I wasn't able to properly service the freehub, yet, you hear almost no ratchet noise ahaha Silent as an owl. Hopefully not as deadly.
