When a chain skips gears, its often attributed to worn or stretched links, but what if thats not the case? What if the issue lies with the cassette or chainrings themselves? Ive seen riders waste time and money replacing chains only to find the problem persists.
Is it possible that the skipping is caused by a misaligned cassette or chainring, rather than the chain itself? Could uneven wear on the teeth or a slightly bent ring be the culprit? If so, how would one diagnose and correct this issue? Would a simple adjustment or replacement of the cassette or chainring be sufficient, or would a more thorough overhaul of the drivetrain be necessary?
Furthermore, what role does the derailleur play in this scenario? Could a misadjusted or malfunctioning derailleur be contributing to the skipping, even if the chain and cassette/chainring are in good condition? If so, what are the telltale signs of a faulty derailleur, and how would one go about repairing or replacing it?
It seems to me that theres often a rush to blame the chain, but what if were overlooking a more nuanced issue? Id love to hear from experienced riders and mechanics whove tackled this problem before. Lets get to the bottom of this and stop wasting time and money on unnecessary chain replacements.
