Take round file and do each tooth it's a dirty fix but works, the file must be same size as the tooth maybe slightly smaller just don't make the teeth larger as this will stretch the chain, the idea is to make them deeper.

When should I replace my.... Chain? When the chain checker says your chain is over 0.5% worn. Cassettes? When you start experiencing "skipping" in your most popular sprockets. Chain rings? When you see very obvious "shark teeth" on your chain ring teeth. Yes, it is true that there are more reasons why you should replace these components, ...

Two main schools of thought exist. New rings every X cassette replacements, and new cassette every Y chain replacements. This required consistent records kept up to date correctly. Nowdays this is much easier with software like Strava, provided you set up the parts on your bike. This is the more-expensive method in the short term, because you are ...

I think that one rule of thumb I saw asserted that if you replaced promptly, you could get 2-3 cassettes per chain, and 2-3 sets of chainrings per cassette. I'm not able to provide a concrete source for this right now. However, the fact is that chainrings do wear more slowly than cassettes because they have more teeth. I think very likely that your cassette ...

No! No! No! A thousand times no! A worn chainring engages to a new chain (and a worn chain too). A well-worn chain does not engage to a new chainring. So in fact the converse is true: you don't want to replace chainrings when replacing the chain, but you do want to replace the chain when replacing a chainring. I have a crankset with visible shark toothing in ...

Any 10 speed Shimano and SRAM road bike shifter should be compatible, except for the Tiagra 4700 which has a different cable pull ratio. Edit: As Pisco points out in the comments, 10 speed GRX (and potentially future 10 speed groupsets) uses this new pull ratio as well. You could try to find used Tiagra 4600 or Shimano 105 5700 shifters. You could go for the ...

The ST-R4600 is a Tiagra model of shifter that is 10 speed but follows the the engineering of all Shimano 7, 8, 9, and 10 speed road shifter/derailleur's having a cable actuation ratio of 1.7:1 (derailleur) and the shifter pulls the necessary amount of cable. With the release of Tiagra 4700, the shift actuation changed to be like 11 speed road despite ...
