Professional software developer for multithreaded, low-latency, time critical code. Formerly engaged in embedded software for medical engineering.

I'm a bicycle nut who owns five bicycles, from an Enduro MTB to my relatively new Velomobiel Quest. Yes, some of my bikes are more expensive than my car was. I do all maintenance myself and have even built three of the bikes from parts.

If there's time, I do some electronics, mainly high-power LED and microcontroller stuff.

comment Reuse oversized hardtrail frame to build a commuter bike?
@joelmdev I found that my TT bars actually give me less problems with impinged nerves than either the flat or drop bars I had before. I don't use the super-aerodynamic, ultra-thin, no bar tape variant though, but rather the Profile Design Air Wing, with additional gel pads under the bar tape to increase diameter and lessen vibration.

Also, where does the OP say anything about drop bars? I wouldn't commute on drop bars if it can be avoided. I have tt bars on my commuter which I find way more comfortable.

comment Minimal gear for dry winter riding in the city
No it doesn't, because it's attached to the handlebars and turns with them.

comment Is front-suspension a false-economy for cheaper bikes?
A very important point: The fork is more expensive than a rigid one, so the bike maker has to save money on other parts, e.g. gears, hubs, BB, wheels, tyres. Most often, this tradeoff isn't worth the (bad) suspension you'll get.

comment Cleaning Carbon Black off a Bicycle
The smoother the surface, the easier it should be to clean. Very rough powder coats can be a major pita in this respect.

comment Cleaning Carbon Black off a Bicycle
Is your frame powder-coated or painted, i.e. is the surface smooth?

comment Use a lock nut on a presta valve?
@Johnny I have Presta valves on my MTB, and there I had the problem. On a road bike, you're quite correct; the much higher pressure will keep everything together nicely.

comment Use a lock nut on a presta valve?
@Vorac However, if you use the nut, you'll need to have the tubes powdered with talcum or some such to further prevent them from moving. Otherwise, the tubes may stick to the tires and move during a hard stop, ripping the valve out in the process. Very annoying, especially if you don't carry a spare.

comment 90 mile round trip work commute
A note on velomobiles: having to start at e.g. traffic lights is quite painful due to weight and riding position. So if the commute has lots of stopping points, e.g. goes through several major cities, think twice before putting down the sum for a small car.

comment Old Kalkoff cross bike, worth restoring or not?
Also, no offence intended, the bike seems to be in use. Is this actually your bike or are you trying to assess if it would be worth it to buy and or "acquire otherwise"?

comment Old Kalkoff cross bike, worth restoring or not?
This bike looks as if it was working, otherwise, why would it be chained up in front of an office building or university? So most likely, some spares as others have suggested and you're good to go.

comment Traveling road bikes that disassemble
I'm not sure whether this is a good fit for the Q&A format. It's basically a shopping question and I think the answer would be readily available on google.
