    Best to start on your own bike. It's not necessary to tear things apart to understand how they work, and some folks do so without learning much.

    These days you can do most routine (non overhaul) maintenance and parts replacement with a Phillips screwdriver, a metric allen wrench set, and a spoke wrench, and cone wrenches if you don't have...

    Let's back up - "chainrings are unevenly worn" may mean the OP thinks that the teeth that are shorter to improve shifting are worn (as cyclocommute suggested). Besides, chainrings take a very long...

    Yes, but be careful when putting the spokes into each flange that they have the proper offset and that you start the 4 spoke pattern in the proper place so as to have the valve hole between groups of...

    Go ahead and do it - no problem. Sometimes it's easy to miss the first cross on a 4x.

    Unless you are the reclusive type I think in-person learning beats everything else, given that you are helped by a person who helps you understand the why as well as the how. Check out The Austin...

    Well, I picked the two scenarios that were the most likely, not the 1/2 of 1% one. You did not previously provide us with that info, so we're not the ones looking a bit silly.

    Did you go straight to ebay or other specific providers or did you 1st do a general Google search? A search for tamper proof torx metric bolts yields several suppliers.

    Note that one will build up less potential energy going up the hill, thus the downhill speed will be somewhat lower.

    That should be addressed before worrying about other things. Check saddle fore-aft position and tilt (nose not down) distance to bars, and consider cycling gloves if you don't have them, and bar ends...

    Spokes that aren't weaved together don't touch at the cross.

    In my opinion either one has the ability to source the properly operating, compatible used parts for a build AND install them, or one has neither ability. I don't blame the shop for not wanting to...

    +1 Assuming a 20 lb bike your bike when moving weighs 165 lbs (you + bike). Even dropping 3 lbs off the bike is only a 2% difference, which will make much less than a 1% difference in speed/effort,...

    1. You are probably better off selling a bike that does not meet your wife's needs and buying an appropriate one than you are upgrading. That is true both from a money and time/effort perspective,...

    If you Google Chicago bike co-op one of the resources may be helpful to you.

    OP states toe-in already done.

    As the rim is the variable there must be something about the rim in combination with the pad that is causing the problem. The rim design typically causes a whirring...

    No, it is not reasonable to assume that everything is compatible. Doing so can lead one down a long but unproductive path. In fact that question is one of the first that should be asked (along with...

    There are numerous ways to determine what part of a frame is bent, but that still does not help you correct the problem. It would be best if you had in-person help to determine where the problems...

    No, the housing (not the cable) is not kept "as short as possible" but rather the length required for a smooth curve, neither stretched nor overly long. It's not unusual for low end bikes to come...

    I agree with checking the cross point. If any spokes were poorly tensioned in the past they could have developed burrs that cause noise when the spoke goes from a stressed to relaxed state. Sanding...

    Did it work at one time and then stop? Did you take it apart and reassemble in between? Or is it a pair you just put on and never worked right. It's quite possible to put a part on incorrectly, or...

    I also missed that it's currently unavailable - too early in the a.m. I guess. I think a return is best if possible. If you can't return it, or can't swing the extra 90 (less than the cost of...

    As noted above it's not just a matter of removing the stem shifters and slapping on brifters. You need a specialized tool to replace the freewheel and some experience helps in replacing and adjusting...
