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 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.

@user29020 I refer to tire rubber... My mistake, I'm correcting it, thanks!

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...

comment What defines a “compact” road bike?
@DanielRHicks The mixte frame is an interesting case, since it has the sloped top tube that gives more clearance, while having its seatstays relatively high at the seatclamp, thus not having as much influence on exposed seatpost length and flex. Some say those parallel tubes running from headtube to rear axle are extra weight without that much extra structural strength, but the resulting DESIGN is surely remarkable no matter what!

comment What defines a “compact” road bike?
Having assembled a classic (non-slope) frame of a larger-than-recommended size for me, I'd say a sloped top tube has AT LEAST the (rather understated) benefit of MORE SEATPOST FLEX, thus softening road harshness a lot (I didn't realized I would miss this so much). So, a compact frame might be a good choice not only for racing-performance reasons, but also for long-distance riding at a slower pace...

comment Why do some road bikes cost more than motorbikes? Are they grossly overpriced?
Agreed, and I'd add to it that, beyond a certain level, you need to throw A LOT more money to get not-so-much additional benefit, so the "price vs features" is not linear at all between entry-level and top-level, creating an abyss if you shift these exponential curves to compare a low-end "lo-tech" product with a high-end "hi-tech" one.
