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 New chain is pre-lubricated, should I clean it?
I'd rinse if the ride is wet, because the dirt necessarily got inside the pins. A dry dusty ride does not prompt for cleaning if the chain doesn't sound squeaky IMO. There is an understanding that it's the dirt that causes wear, not lack of lube (which itself would lower drivetrain efficiency due to friction). Sheldon brown has the best article I've ever read about chainwear, it' enligtening.

Well if the chain is ALREADY dirty, I would clean it before putting it on the bike.

comment Does this chainring need to be replaced?
@Kaz you're right, but only if the chainring is symmetrical, which is usually not the case with indexed rings. Even "flat" chainrings usually have a lowered edge in one side of the holes.

comment Rear hub for randonneuring - any “classic” model?
"I would probably not choose American Classic for randonneuring" - could you elaborate on that?

comment Rear hub for randonneuring - any “classic” model?
@DWGKNZ I agree that some boutique parts are a bit overpriced, but Chris Kings are the epytome of "expensive" (if not outright overpriced) to me. I am taking a look at Grand Cru, from Velo Orange, and that looks great AND less expensive... (not that CKs are bad, not at all, but expensive...)

comment Solid rubber bicycle tires
It is worth noting that the very invention of pneumatic tires by Dunlop a long time ago was responsible for a huge development and widespread use of the bicycle as a vehicle.

comment Is it really necessary to physically cross (interlace) the spokes on traditional wheel lacing?
I have tried myself to build a passing wheel, but couldn't because the spokes would leave the flanges at too narrow angles, thus not "wrapping" enough around the flange. I suspect this would make the spokes flex a lot around the elbow, thus braking due to fatigue. Then, it seems to me that supporting them at the middle (via crossing) increases the wrapping AND decreases the flexing at the elbows during use.

@DanielRHicks Gonna try some silicone spray this weekend and post some feedback, thanks!
