Renegades

Carlos can tell you the following about them:
The Renegades are okay guys as long as you don't cross 'em. They only run drugs on the side and only a little bit of Eclipse.

Mostly, they keep the roads out of town on lockdown and raid anything that looks tasty. They pull down the serious cred. Anybody rich enough to still have a car probably has expensive goodies. To say nothing of the truck caravans. Good money.

The cycle chain description also gives you a detail about their modus operandi.

The raider mask might come from the Renegades.
