How can you be certain that your derailleur hanger is properly aligned when attempting to fix gear slippage on a gravel bike, and what methods do you use to verify this alignment, considering the countless variables that can affect it, such as the type of hanger, the frame design, and the derailleur itself, and isnt it true that even the slightest misalignment can still cause slippage, rendering the entire process pointless.
And what about the cable tension, how do you determine the optimal tension, and what tools do you use to measure it, and isnt it possible that the recommended tension values provided by the manufacturer are not accurate for every specific setup.
Furthermore, how do you account for wear and tear on the components, such as the chainrings, cassette, and chain, and at what point do you decide to replace them, and what criteria do you use to determine when they are worn out.
And what about the role of the limit screws, how do you set them properly, and what are the consequences of setting them incorrectly, and isnt it true that even a small mistake can cause the derailleur to malfunction.
And finally, how do you troubleshoot the problem when youve tried everything and the slippage persists, and what tools and techniques do you use to diagnose the issue.
