Compatible with X7 advanced Cog Set on stock wheel set for up to 7 speed 11-28t (#X7AdvancedCogSet), or you will need to pair with 3rd party rear wheel with multi-cogs compatibility to take 7 or more cogs (7 speed/28t possible), these are not included.

  • Titanium Tensioner Spring.
  • Smooth surface treatment with multiple colours to match your style.
  • Limited colour might only be available in 1st batch production.
  • Listing is default only one tensioner arm for P/T Line (compatible to stock advanced parallelogram derailleur up to 5 speed 22T). You can add optional parallelogram derailleur (Spring activated main body, 2 Jocky wheels, fixture for further gear range). Cogs, thumb shifter, shifting cable and 3rd party upgrade wheelset are not included but optional.

  • Please see A/C Line version in this LISTING.


Note :

  • This modification is more difficult than the rather easy "plug and play" X3 Unibody Cogset external 3 speed upgrade. (please expect some more time and patience to finetune the result).
  • Do not recommand this as a DIY project, please consult your LBS mechanic before order.
