comment Bicycle lights- Indicating in the dark
@CearonO'Flynn looks like the surface quality of the streets you have are fare better than mine's. Not to mention drivers' disrespect around here. Thank God they started to increase the number of bike paths recently.

comment Would hydraulic disc brakes be easier on my hands than mechanical disc brakes?
@Emyr Yeah, you are right, I guess I meant static friction... Anyway, compared to a sub-optimal cable, the friction is much lower.

comment How to fix a stripped pedal crank
@RoboKaren I agree aluminum is more difficult, but definitely possible. The ones I have seen fixed that way were aluminum.

comment What is the usual pattern of use of a velodrome (cycling track)?
Hi, Andy, thanks for your nice answer! Unfortunately, not only we have not got any velodrome but also, despite the steady increase in bicycle use in my city, City Hall has shown itself as the worst I have ever seen regarding policies for use of open and public spaces... Anyway, there is growing discontent from every possible segment of activism, and we hope to raise awareness so that future politicians should be elected with different priorities than, shopping malls and abundant car infrastructure :o(

comment Why are hand-built wheels considered to be better than machine-built wheels?
I agree the second and third points are a bit speculative, but the "bending-around-crossing" technique gives the spoke a characteristic shape that I haven't seen in any other wheel than the ones I laced myself, be it machine-built or not. So I assume this bending is not usually performed in industry or by local mechanics, but rather only by more crafted wheelbuilders (or ones that read Sheldon Brown a lot).

comment How do I maximize my upper body workout from riding?
@Vorac as I understand, there is room for training super-high cadences and also more slowly-grinding ones. Usually, what is not recommended is to ride low cadences like everyday, at cruise-speeds.

comment Are road brakes designed not to brake too much?
Good point on bad mechanical advantage from the hoods. But actually, I am riding a flat bar road bike, so I use V-Brake levers. Anyway, this is a common complaint between fellows with much more experience than me, riding drops and all.

comment New chain is pre-lubricated, should I clean it before use?
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.

comment New chain is pre-lubricated, should I clean it before use?
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!

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.

@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".
