Sticky/Unresponsive Road Shifters

If you are experiencing difficulty with your road shifters, it is likely that the grease inside of the mechanism has accumulated dust and no longer catches the shifting thingy. It may be good to mount the bike or place it upside down (much harder) so you can shift easily.

Squeeze the brakes until you see the inside of the shifting mechanism. Spray a liquid penetrant like Pb Blaster or Kroil (NOT WD40) inside of the mechanism and try shifting up and down repeatedly for a couple minutes. You should notice an improvement, but it probably won't be fixed. Wait and repeat in a couple of hours.

Once finished, get some compressed air and flush out any gunk in there, and some isopropyl alcohol if you want to be super thorough.

Derailleur Adjustment/Indexing

You will want the bike mounted or flipped upside down so you can pedal the bike for shifting gears.

Set the limit screws

On each derailleur, there is a high or "H" and a low or "L" screw. These maintain the limits of how far your derailleurs will go towards or away from the frame.

Shift to the lowest gear and adjust the "L" screw to where the derailleur is perfectly aligned with the gear. You will see it move side to side. If you don't, you're probably turning the wrong way. If it's not moving enough, you may need to adjust the cable length.

Repeat this process with the highest gear and the "H" screw.

Set the gear indexing

This will calibrate the gear shifting to not skip or go halfway on shift.

Start at the lowest gear. While "pedaling", shift to the next gear. This is when you are testing the fluidity of the shifting, so stop once the shifting is not occurring as expected.

If the shifting is not occurring as you'd like, you will want to adjust the barrel connectors until the derailleur is directly above the desired gear. On the front derailleur, it will be on the downtube; on the rear, it will be attached to the derailleur. As you adjust, you should see the derailleur move side to side.

Once the index is accurate, continue on to the next gears until complete.

Truing Your Wheels

Lateral Truing

Set Up

Start off by taking the tire and innertube off of the tire. Sometimes the tire and tube can obfuscate the actual shape and curvature of the rim.

Place the zip ties on the fork (for the front tire) or the frame (for the back) perpendicular to the rim. You want to place them and clip their length so they can eventually be rotated closer and closer to the rim as your rim gets more and more straightened out.

Mount your bike or flip it over onto the seat so that the tires can rotate freely during testing.


In short the process is:

Here is the process in detail:

  1. Set the zip tie a few millimeters away from the edge of the rim. The goal at this step is to ensure that through a full rotation, the zip tie doesn't touch the rim, but gets close.
  2. Rotate the zip tie inward towards the tire about as little as you possibly can.
  3. Spin the wheel slowly, watching and listening for the zip tie to make contact with the edge of the wheel.
  4. Repeat steps 2 and 3 just until a zip tie makes contact with the rim. You want the least amount of contact with the rim possible.
  5. Once you make contact, manually rotate the wheel, watching and listening for the loudest (most out of alignment) section. Aim for finding an area about as wide as one or two spokes.
  6. Find the spoke nearest to this section that goes up towards the side of the hub opposite of the zip tie that is touching. For instance, if the zip tie on the right is touching the rim, you want to find the spoke that meets the hub on the opposite side of that zip tie.
  7. Place the spoke wrench on that spoke nipple and tighten it a quarter turn. Some important notes:
    • Tightening and loosening are done from the perspective from the tire side of the rim. It will probably feel like you are doing it wrong. Quoting, "Imagine using a screwdriver to tighten the nipple from the tire side of the rim, then turn the nipple the same way using a spoke wrench on the spoke side of the rim, and you’ll be fine."
    • You almost always want to tighten your spokes instead of loosening them. Avoid loosening as this could cause your spokes to loosen up while riding and destroy your wheel's integrity.
    • Don't do more than a quarter turn at a time! It's tempting, but be patient.
  8. Check the rim again, rotating the wheel around the same section. If you still hear the contact, go back to step 5 and repeat. If it has gone away, go back to step 2 and repeat.
  9. Once this process has been done repeatedly, you should have a relatively laterally true rim.
