Appropriate_Ad7703 on December 15, 2025 4:46 am So I think I messed it up but not sure I kind of messed the derailleur up a little while putting the chain back on does this look fine? https://preview.redd.it/9zmapuslsa7g1.jpeg?width=3024&format=pjpg&auto=webp&s=72bba3a38f2aed886266804875acdaeb4c9503b3
Buffalo_Theory on December 15, 2025 7:46 am if it’s got any chain tension it’s fine. though i have a premonition that your shiny chainstays will get chipped paint from chain slap within 1 day of riding … and that’s got nothing to do with your chain length …

Can I ask what bike?
Looks good to me
