The first titanium replacement cage. The construction of this cage has improved the overall durability of the cage and reduced its weight by 50% over traditional carbon steel wire cages. While this may not seem like a big deal, consider the fact that this cage combined with a lightweight helmet (such as Mission's Intake) weighs less than the majority of helmets on the market without cages! The titanium construction is much more durable than traditional carbon steel cages as well making this quite possibly the last cage you will need to buy EVER!.
