I'm a self-teaching geek. teaching because that process is far from over. I don't know a ton, but what I know, I'll share, and I won't answer a question if I'm not confident I'm correct.

comment Quick question about V-Brakes?
Shorter life and more power, but far less control of that power, compared to either canti's or discs.

comment Why has indexed shifting displaced traditional friction shifting?
"...and the answer is usually..."It's too hard." or more likely, "It shifted OK when I got it, but now it doesn't work." Kind of sad." Truth. But more likely a problem with the rider's lack of knowledge or motivation, than with the equipment they've got.

comment Why has indexed shifting displaced traditional friction shifting?
I'm sorry if I come across a little annoyed about the question. But I am. You're a Microsoftie, right? This is a little like me buying a first gen EeePC, and then complaining to you because it has no optical drive, or I can't use it to crack a 128 bit TLS key in a usable time frame. Buy good equipment first. Then complain if it doesn't do what it is intended to do. Wouldn't be a bad idea to take your bike down to Woodinville Cycles in Redmond, downtown not Overlake, and ask them to check whether it is adjusted properly to start with.

So my suggestion would be, learn proper shifting patterns, first, and then consider upgrading your Trek 1500 to something a little more performance oriented before you complain about how the old days were better. You look about 20, BTW. Have you ever ridden a road bike with straight friction shifting?

comment Why has indexed shifting displaced traditional friction shifting?
That cog position, commonly called cross chaining, is not recommended for several reasons. The biggest reason is that it causes unnecessary wear and tear on your drivetrain. on an old school bike, with 5-6 rear cogs spaced fairly widely apart, you could get reasonably accurate sifts with a friction shifter and a little practice. Put 10 rear cogs in the same space, and it gets orders of magnitude more difficult. In addition, most quality indexed shifters on a road bike offer a "trim" position on the front shifter. A half shift up or down specifically to address the needs of stubborn fogies.

comment How can I adjust for uneven brake wear?
Did you try to move it as I suggested, or are you assuming that it won't move because it looks flat?

comment How can I adjust for uneven brake wear?
Although that isn't usually the case with any Shimano brake, if it is here, then your best option is to replace the pad holders with a new set. You can buy a 105, or Ultegra level pad with the holders and the adjustment washers for around 50 USD a set. This appears to be a Trek 1500, from around 2003-2004 based on the fork and the graphics. Should have 9 speed Tiagra components? Is that correct?

comment How can I adjust for uneven brake wear?
There are. I can see them in the picture. Unless that isn't your bike? They don't look like they offer adjustment, but they do.Try tightening the brake pad fixing bolt just enough so that you can fell a little tension on the bolt. Then grab both ends of the pad holder, and try moving it in the plane of the change you're having trouble with. It should move, if a little stiffly. I would leave the bending of the arm adjustment to a shop, unless you are very confident. It's a legit technique, Park even makes a tool just for that, but it can cause permanent damage to the brake if done badly.

Explain please. Mine does cadence.. or are you talking about logging cadence breadcrumbs on the data center?

comment Why don't road bikes use v-brakes?
I'm certain that weight and aerodynamics do play a part in the commercial calculation made when a frame is built. And there are some cyclocross and touring, and tandem machines that have started incorporating disc brakes. I haven't seen any that use V-brakes. But if they did, it would not be good design.

A couple of decades ago? I wonder if tire tech has changed any in 20 years? I know my bike is the exact same model as my dad's bike was...

comment What is the narrowest tire you would use for commuting?
On a road bike. Which will not have 1.5" tires. And you should discuss that with the RTA in your town. We have asphalt roads, and 50c temps regularly, and I've never had the asphalt create a resistance issue. Unless it was fresh laid uncured paving...

comment Repairing a twisted front rim in emergency?
@hhh: A ten kilo walk, rather than riding a barely functional, unsafe bicycle is also a valid response to an emergency. And is less likely to cost you money later.

comment How to get a very tight tire back on the rim?
I have. It's essentially a thick plastic lever, with a notch on the end. The idea is once the lever is under the bead of tire, you can slide around the rim, with no additional levers. It works well to get tires off, but I've had problems with pinches occasionally putting a tire on. Not often, but they are thick, and can be ungainly. Pic here: bit.ly/ldCCQp

Your welcome. Sorry it's probably not what you wanted to hear.
