The inline barrel adjuster for my front derailleur cracked and a piece of the collar broke off, creating a kink point in the cable. The adjuster is 4mm by Jagwire.

Q: Will a 4mm barrel adjuster by any manufacture work as a replacement?

I have a bar-end shifters with deore xt drive train. The bike is a REI coop adv 3.2 (i.e. gravel touring bike)
