Before any bike is disassembled, we check the function of the drivetrain components. Sometimes we have to clean, straighten & tune the drivetrain before we can fully understand what we are working with. We check the function of each component thoroughly before disassembly begins.


We check every crankset for cracks & scratches. We rarely sell any crankset with the chainrings - nothing is more disappointing than to install a new-to-you crankset only to have your chain skipping as soon as you begin pedaling. We make notes of the following measurements:

  • length

  • bottom bracket interface or spindle type

  • bolt circle diameter and arm count

  • any printed information on the crankset


We check every shifter for performance and condition. We are looking for a crisp feel and precise movement. If that isn’t happening, we continue a bit further with our service.

Here in the desert dust of Arizona, it is a common occurrence that shifters will need to be flushed. We take our time and flush the inside with a light cleaner. We use low pressure air to blow out as much grime as we can. We may do this procedure two to four times until function is smooth and crisp. We then use a light lubricant to protect the parts, use low pressure air to blow out any excess before testing the function again.

We document every detail such as:

  • brand, model and part numbers

  • front chainring count, if applicable

  • rear derailleur speeds

  • condition of levers - scratches, chips

  • condition of hoods


Before disassembly, every derailleur is tested for performance. Once disassembled, we thoroughly clean and lightly coat the springs and moving parts with a lubricant. The pulley wheels are inspected and replaced if necessary (and the value deems replacement worthy).


We rarely sell bottom brackets. The only exceptions are those bottom brackets that are either:

  • rare and unique

  • are in good condition and match a specific crankset (which they are provided with)


Like the rest of the drivetrain, we check over the electronics before disassembly. We cycle through set-up and tuning to make sure the next owner will not have any issues.We make sure batteries will hold a charge. We make sure the connections look clean and reliable.


Rim brakes are pretty straightforward - they usually work well unless they’re broken. Our biggest concerns are always:

  • smooth function - everything moves easily but does require some strength to move

  • pad life - we do not normally replace the pads so that the new buyer can replace the pads with what they like.

  • essential hardware - all the appropriate nuts and washers

  • finish


We test disc brakes before the bike is disassembled for performance and reliability. We will:

  • bleed the (hydraulic) system to check for leaks and to inspect the old fluid.

  • check the piston movement to make sure they are moving freely.

  • check the lever function at the bar and at the caliper (if mechanical).

  • inspect the pads. If pads are more than 50% worn, we will remove the pads and not replace. Many buyer want to replace with pads of their choice.


Chains and cassettes are discarded, trashed, thrown away. We do not inspect every link nor every tooth. There is no worse feeling than a skipping chain or cassette. If you want some old chains to make art with, let us know. We’ll save em’ for ya….
