UPDATE 05/08/2025: added a variant for 11/12 speed chains (thanks @GrzegorzZ)

UPDATE 28/07/2025: after further testing and reviews the model geometry was updated to avoid wicking lube to the sides

This is an applicator for Squirt Chain Lube bicycle chain lubricant. It's designed with specially positioned internal channels that deliver the lube precisely where the parts of the chain meet.

There are 2 variants so far:

• For 6 speeds chain with 7.8 mm outer width 
• For 11/12 speeds chain with 5.3 mm outer width (SRAM GX 1x12 or Shimano Ultegra)

Not guaranteed to work with other chain sizes. However, if you provide outer and inner width measurements of your chain, I'm willing to create a version for you.

Usage tip: clean the channels after each use (for example, by blowing through them) - otherwise, wax-based lube will harden inside, and you won't be able to use the applicator again.
