comment Cable routing and why is there no optimum solution
As to why there is no "optimum solution", that's just the way life is -- everything's a compromise of some sort.

comment Cable routing and why is there no optimum solution
@Kibbee - There are top-pull front derailers. And it used to be common to have pulleys for the front derailer cable, so running across the top, down the seat tube, then back up to a pull-down derailer would not have been out of the question. But, as I suggested, usually the front derailer cable runs down the down tube, to minimize length and turns.

comment V-Brake levers for drop handlebars?
You can get the "Travel Agent" cable adapter, though there are reports that cable breakage with that is a significant problem.

comment New 26“ inner tube different size to old 26” inner tube
(And understand, as Mike says, that 26 x 1.5 is NOT the same as 26 x 1-1/2.)

What numbers are on the side of the tire?

comment What is a wireless crankset?
Yeah, I've never had a crankset with wires on it. Did get some vines wrapped around them a few times, though.

comment New 26“ inner tube different size to old 26” inner tube
It's not clear -- how much have you inflated the tube? With it uninflated (laying limp) is should fit inside the tire without "bunching up" -- it's normal for it to expand a bit when inflated, and the tire prevents that. (The image above looks close to "normal" for a tube that's been a bit over-inflated.) But as Mike suggests there are (at least) two different standards for so-called 26" tires.

comment How should I lubricate my Shimano freewheel?
This is a controversial topic. If you squirt any sort of sticky lube into the unit it will only get worse. The "official" solution is to take it apart (which is very tricky) and clean it, then gently relube with the right stuff (which I think would be a thin "white grease"). There are (or used to be) special tools available that claimed to be able to relube an assembled unit -- dunno if they work. (And, in general, a freewheel/freehub should not require service, unless flooded or subjected to severe weather exposure.)

comment Why don't road bikes use v-brakes?
@zenbike - You can install the pulleys that "correct" the difference in mechanical advantage between the two.

comment Why don't road bikes use v-brakes?
@zenbike - The amount of force applied vs "modulation" is purely a matter of mechanical advantage, which can be easily manipulated by adjusting lever arm length, etc. And brake levers can be designed (if the mfgr wants to) to provide more or less "advantage" without drastically changing the lever "style". But Shimano is in the business of selling sex, and "grabbier" brakes are sexier.

comment Why don't road bikes use v-brakes?
@zenbike - V brakes were introduced to do away with the center brake bolt of side-pulls and the need to mount a pull point for a canti brake cable. This was needed mostly for suspension bikes. There's nothing inherently superior in the braking power -- mechanically they're cantis.

comment Why should the front wheel be more heavily loaded when touring?
Speaking from experience: Weight on the front wheel makes the bike more stable. The only caveat is that it be firmly attached -- a vibrating load on the front can be real scary.

comment “Climbing” small steps in 23mm tires
It's never good to face such a discontinuity with the tire at a angle -- always try to approach as squarely as possible. And when faced with such a bump I generally do what I do on RR tracks -- "suspend" my body off the seat and use arms and legs as springs. But I'm far too old, feeble, and set in my ways to attempt a "hop".

comment Higher cadence or lower cadence for long distance cycling
One thing to understand is that there are two types of muscles -- "fast twitch" and "slow twitch". The former are (simplified version) more aerobic -- pull energy from the blood -- while the latter depend more on (limited) stored energy in the muscle. So you fatigue faster when you depend on "slow twitch" muscles, which you do when your cadence drops. (Though that's over-simplified -- lower cadence isn't so bad when energy output is low.)

comment Why don't brakes come with 'Safety Levers' any more?
My recollection is that they were called "suicide levers" for two reasons: One is that they placed the hand position, when braking, too far back for stability. The other is that they easily "bottomed out" when braking.

comment How can I make my own chamois cream?
Yep, it's sold in the US, often in regular drugstores. "Bag Balm" is the best-known brand, though there are several others.
