4. Technical information

General groupset setup: please follow manufacturers instruction for the related group set.

  • Pairing
  • Indexing
  • B-gap

Chain length: Please refer to this chain sizing article as chain length may vary from the manufacturer's recommendation.

  1. Wrap your chain around the chainring and the largest sprocket
  2. Bypass the derailleur 
    • Shimano derailleurs: add 5 to 6 chain links (+ chain lock) to the overlap for correct sizing

  3. Use a chain tool to shorten the chain to the determined length. Ensure that the chain has the correct chain link or connecting Pin for the installation.

Remember that it’s always better to have a slightly longer chain than too short. You can always shorten it later if necessary.
