I ride non-stop since I am 4, my father gave me one bike each 4 years until 18. Since then I am changing components and assembling new bikes. Now I have seven, including tandem, home-made recumbent, fixed gear, city-bike with generator and internal-gear-hub, freeride full-suspension.

I have been bred on XC mountainbike (raced a bit), and enjoy technical terrain, as well as light freeride, randonneuring, and touring. I also like to try to smoke my friends and acquaintances on group rides (and so do them).

I tend to do my own assembling and mainteinence, and am known among friends for a natural willingness to solve mechanical problems "in the field", even those not on my bike. I like to read about deep intricacies in bicycle mechanics, being a strong fan of a lot (but not all) of Sheldon Brown approaches.

Recently, I am engaged on bike as transportation, bike advocacy, and political-related-bike-issues, and participate in a lot of local groups, mostly nightbikers, weekend rides (not club rides) and Critical Mass.

My short-term bike-related goal is to have equipment and energy to commute all-year round (my winter is very rainy), and my long term goal, more like a dream, is to be full-time involved with bikes, professionally (most probably designing/manufacturing or selling stuff).

comment How to clean rubber and plastic parts with sticky, thick teflon-based lube stains?
The teflon lube, as soon as applied months ago, evaporated and left the characteristic wax-like teflon coating inside the working surface of the shifter. But with use, the edge of the shifter was a bit sticky, since some lube was coming out. When I disassembled and started cleaning, the brushing just spread the wax-like, somewhat dirty teflon over the rubber surface. The rubber itself seems fine, but it's dirty with teflon. It's not impossible, though, that it penetrated the rubber a bit, but I would like to try to clean it with a proper method so that I can know.

comment Tires for 28' city bike (622x19C) to reduce rolling resistance?
I used a pressure that provided enough cushioning without the tire bulging or bottoming out easily. That means the narrower tire had higher pressure. Usually I ride at 20 mph (30km/h) cruising speed.

comment Am I going to get injured mountain biking if I don't have rear suspension?
@sixtyfootersdude: That's what I said, "your most likely to get seriously injured with a full suspension".

Fun is when you are at 40mph+ down a fire road on an 1.95 tire XC hardtail, and suddenly an eroded rock garden appears around the corner and you think "OMG, I'm dead"... And you manage to float inside it somehow and emerge ALIVE at the other side... Now THAT is fun!

And no: you're most likely to get seriously injured with a full-suspension that with a hard-tail if your risk-tolerance is high...
