comment How to remove crank arm with broken bolt on SRAM Omnium crankset
You have to somehow unscrew the dust cap/"self pulling" cap and use a conventional crank puller.

comment Have there been designs of bikes with stepless transmission?
Yep, several of the "geared hub" designs are "continuous".

comment Chain vs chainless options
The chain is familiar, cheap because of high volumes, and works well in a derailleur setup. The belt is quiet, smooth, low-maintenance, potentially cheap but not yet high volumes, limited to a single speed unless you have a complicated, expensive multi-speed hub. The driveshaft is complicated, heavy, unfamiliar, probably noisy/rough, probably high-maintenance, and limited to a single speed like the belt. Both chain and belt are quite durable, hard to say about the shaft.

comment How long will my bike last?
You've got more problems than one would expect in 15 years on a decent bike. Either you're really beating it to death or it's a really crummy bike.

comment Biking gloves with finger protection
I think the trick is to stay off the roof with your bike.

comment Seatpost Overextension
Definitely, if the post does not extend down roughly 3 inches into the frame then you're at risk of damaging the frame. And this risk is greater on an Al bike than a steel one.

comment Calf Muscle cramps
(Other than giving you loose bowels when taken in high doses, L-carnitine is fairly harmless.)

comment Calf Muscle cramps
Muscle cramps of the nature you describe can be due to a number of causes: Simple overuse, shortages of potassium, magnesium, etc, several "minor" metabolic disorders (MADD, carnitine deficiency of several flavors), simple dehydration or hypoglycemia, etc. You either need to find a good sports medicine doc/therapist or be your own.

comment Front tyre size - is 1.9" a good option?
Nothing wrong with that, if it fits the rim OK.

comment How do I stop punctures for good?
First, get Kevlar-belted tires. Second, keep your tires properly inflated, to prevent "snake bite".

comment How do I reply to a question?
You scroll down to the box that says "Your Answer" and type. If what you type might be more of a comment than answer, mention that you don't have enough points to use "add a comment" yet.

comment how many bike I can carry in my sedan?
I've seen racks for class III hitches that claim to be able to handle up to 6 bikes. But, from a realistic standpoint, the "lever arm" with that many bikes is really more torque than you should put on an auto hitch -- I think 4 is closer to the practical limit, for adult bikes.

comment Need to know the wrench size for 10.9 screw
Yeah, you use the one that fits. Just be sure you're using metric wrenches, and the one you choose fits snugly.

comment Mechanic says not to use top three/bottom two gears or the chain will throw
@EsotericScreenName - If the mechanic actually said that and meant that, he was stupid.

comment rear panniers attachment catching in spokes
The trick with panniers is to have a large enough hook at the bottom. Depending on the design the hook is either on a strap out the bottom of the pannier, or the hook mounts on the bike and there is a loop on the strap. The hook must be large enough to fully reach around whatever it's grabbing. Sometimes you need to replace the stock hook with something else.

comment Gears randomly switching
What you have is "creep". On any sort of rough surface the vibration prevents it, but smooth surfaces it occurs. Plus you pedal more consistently on smooth. Hard to say the precise cause, but my guess is it's a combo of frame flex and your shifter cable setup.

comment Gears randomly switching
@GrimmTheOpiner - What?? Derailers can last much longer than that, if maintained reasonably well.

comment Pros and Cons of 29 "wheels
1) It's something different to sell. 2) But it's not actually different because these are 700c components relabeled, so less inventory, less manufacturing setup, etc.

This doesn't actually answer the question.

comment How do I replace road brakes?
In other words, remove the old and install the new. Assuming that both units use the same size brake post, there's nothing in the swap that isn't normal maintenance operations, other than the actual physical swap.
