comment Fixie vs Road Bike - the right fixie bike for bunch rides
@DavidTriebe I suspect the real effect is that because you get much more accurate feedback on your pedalling due to the wheel's momentum driving the chain, it's easier to learn and maintain good timing. This can easily feel like you're getting more effect from pulling up, but in reality you're just doing a better job of correctly unweighting the pedal on the upstroke.

comment How do I prevent my chain from dropping down while going downhill on bumpy surfaces?
All standard bicycle chains have 1/2" pitch (the distance between the centres of two adjacent rollers). So, 24 half-links should always measure exactly one foot, and all feasible amounts of chain wear will leave this off by less than a whole link. IIRC 1/16th of an inch over one foot is the threshold for replacing a chain (and 1/8th is the threshold for replacing the chain and sprockets).

comment Looking for fenders similar to SKS Bluemels Primus, but available in the US
I think the PDW fenders have the sort of profile you want, and though the stays loop over the top, they don't exactly stick out.

comment First long bike ride: Determining the cause of saddle soreness
+1: If the OP could feel blood returning when standing up, that sounds like the soft tissues are taking weight instead of (or as well as) the sit bones. Padded shorts and other things can certainly be helpful, but the saddle still needs to fit correctly first.

comment How do I make my bicycle as ugly as possible without affecting the riding qualities?
True, I wasn't sure it'd take well to all surfaces.

comment Spokes keep breaking
Where are the spokes breaking? At the elbow (where they attach to the hub), or the nipple (where they attach to the rim)?

comment converting stem shifters to brifters
If you're not sure about all the individual parts, take a look at the complete kits on wiggle, chainreaction, SJS or another good retailer. Or, of course, find a good local bike shop and take it in.

comment converting stem shifters to brifters
By "main stem", I assume you mean the down tube. You might find a diagram like this helpful since the names aren't always obvious. For the cable stops, you're looking for something like these to bolt into the existing shifter braze-on.

comment Are Hövding helmets safer than regular helmets?
There's a video somewhere of a wearer accidentally triggering the airbag while pulling on a jacket. I can't find a link immediately, but it certainly supports the false triggering hypothesis.

comment Wheel builder London?
I agree this is probably off-topic here - try a London-specific forum like LFGSS. The atmosphere can be a little robust sometimes, but I can't think of a better place to find East-London wheelbuilders.

comment can you use a cycle path to bypass red lights?
Since I regularly see drivers getting this wrong, it's worth being clear: the light only controls the stop line. If you don't cross a line, it doesn't matter where the light is or what colour it's showing.

comment Will disc brakes aggravate the problem with spokes pulling through the rim?
In the nicest possible way, you asked a question and got an answer. This isn't really the right format for long conversations; it works better to ask follow-up questions as self-contained new questions on the site.

comment Will disc brakes aggravate the problem with spokes pulling through the rim?
There will definitely be more strain on the NDS braking spokes, yes, but it shouldn't be problematic if the wheel is built correctly. Just to reiterate, something is terribly wrong if you routinely have spokes pull through a rim, and while you should fix whatever is causing that, it's not a good foundation for reasoning about other wheels.

comment Are road brakes designed not to brake too much?
Do you mean it's harder to (exert sufficient braking force to) lock the wheels, or takes longer to actually stop? IMO the former is false, unless your brakes are set up badly, and the latter is true and explained by having a smaller contact patch and (as Z. Fechten said) higher speed.

comment Coping with crash fear?
Do you understand why you crashed? Figuring out what happened, and what to look out for so you can anticipate, avoid or ameliorate it in future, is generally helpful.

comment Is there any rule of thumb for comparing lights rated in lux and lumens?
No clue. I've seen OP's light wearing a few different badges, and I was hoping the comparison would include one of the rebranded versions. Couldn't find one, but maybe OP knows that light well enough to tell roughly where it sits.

comment Why is it important to keep equal number of turns when building a wheel?
No, if the rim is warped, you'd expect quite different tensions/number of turns. Some spokes will be carrying only the "base" tension, and some will be doing extra work correcting the rim.

comment Is this a puncture protection thing?
I think tubs are supposed to be more resistant to pinch flats, but I'm not aware they're less liable to sharp punctures

comment Do merino wool base layers need to be skin tight?
As an aside, the work wicking refers to a fabric's ability to transport sweat, not heat. Cooling still depends on airflow (which you've blocked with the jacket)

comment Is it normal for a fixed gear bicycle's rear wheel to slip forward in its dropouts from time to time?
A chain tensioner normally refers to a sprung jockey wheel thing used to take slack out of the chain (it wouldn't help here and isn't recommended with fixed gears anyway). If you have chain tugs though, figure out how they're slipping, because they shouldn't.
