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 Are single-speed bikes better equipped to handle cog/chain wear?
@Kibbee I agree that this seem to make sense, but in my experience that's not how it "actually happens", for two reasons I think: 1) it is different to ride "wrong gear" with a derailer bike, which suffers from that (it's not the intended use) and with a single-gear bike. Single-gear is DESIGNED for that, besides being beefier and always aligned (no chain crossing). Also, singles are very efficient, and you can keep the bike moving uphill even at very low cadence, without abusing neither the drivetrain nor your own legs. There are no "wrong gears" with singles.

comment What factors determine stem length ?
@Jahaziel also I found that the force over the wrists depends not only on torso angle, but also on hand position relative to the hips, which is the pivot point of torso rotation. The closer to the hips the handlebar is, with any given torso angle, the greater the reaction force needed to counteract the torso's-weight-generated TORQUE around the hips. So, sometimes a lower, longer reach can be more forgiving to the wrists and shoulders than an upright, cramped cockpit, specially while braking or going downhill.

+1. The explanation about differences in stem lenght is exactely what I feel about it. That would mean you can have different handling with the same reach, by varying the (top tube + stem/bar) combination.

comment Can Garmin Edge 500/510 and 800/810 be charged while riding?
A different approach would be to plan ahead and ALWAYS let the device recharging at the checkpoints. Easier to say than do... (but you'll have to rest anyway, won't you?)

comment Can Garmin Edge 500/510 and 800/810 be charged while riding?
I have used a Garmin eTrex Vista HC without batteries, plugged via USB. I didn't remember if it switches between different modes upon plug and unplug, but I believe you could put rechargeables inside and also plug it to a generator-hub usb adapter. Actually I plan to do this with my new smartphone.

comment Training fasted: just about weight loss?
A bit of not-so-scientific knowledge, but if you eat just after moderate exercise, there is a peak of nutrient absorption. This means not necessarily fat buildup, but glycogen restoration and other muscular nutrients restoration, such as proteins.

comment How much of the saddle rail is suiteable to use
In my experience there is no problem to go beyond the marks in either direction (some rails don't even have the marks) but it would be interesting to hear from someone else if those "limits" are actual safety limits or just loose recommendations...

comment Repurpose old android phone (without cell phone plan) as cycle computer with GPS tracking?
+1 Very nice considerations. I cannot help but say, though, that along with all these extremely nice features comes the "price" of dependency. In some circumstances, when magic stops happening, and there is not a lo-tech backup alternative (offline, paper-based, etc.) this can be an issue. It applies mostly to navigation/localization, but may apply to monitoring and logging too. Well, just a thought.

comment How can I increase the highest gear ratio?
Could you find out how many cogs, and how many teeth each one, you have in the rear, the same for the back, end include this information in your question? Then we will be able to give you much better advice! :o)

comment How to avoid knee pain when cycling
I noticed that moving the chair around using leg flexion (pulling you closer to the desk by your feet pulling the ground back) can cause specific discomfort if you do that often...

comment GPS with maps for touring / using an iPhone
eTrex is in fact a product line. THE entry-level eTrex (yellow one) is quite minimalistic, and unfortunately the price slope is quite steep from one model to another. Not to say that sometimes you get a lot of functionality you don't want (and pay for it) just to get one extra feature from the next model in the line...
