comment can i use a 700c tire (Gatorskin 700c x23) on a 650 wheel
If you have rim brakes you'd need to change those out. Pedal clearance will be less. Not a good idea, generally.

comment Axle flex under load normal for freewheel hub?
Kickstands are classically a problem for tire rubbing, in large part because they tend to rotate on the mounting bolt. And as Alan says, frames flex under load too (as do wheels). Without observing it closely it would be hard to guess what component is flexing.

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.

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 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 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 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.

comment Credibility of my Bike fit
MADD symptoms are based on the total energy expenditure in the muscle over a period of a few hours -- brief intense periods (sprints) are not as problematic. The only symptomatic relief comes from D-ribose, which is available as a "supplement" and which is also present (at relatively low levels) in "organ meats" and in lentils. The symptoms are exacerbated by statin drugs. If you have the condition the symptoms generally vanish (except perhaps for local areas of damaged muscle) within two hours of taking a several gram dose of D-ribose.

comment Non Removable Presta Extension
Just by long-stem tubes. Heck, it's harder to find the short stems that work best in my regular rims than to find the long ones.
