Wired Bliss TCUs and Quads

Summary: Introduced in 1984, Wired Bliss cams began the TCU revolution. They still hold a respectable position near the top of the heap, featuring long stems that make plugging the cams into the back of flared corners a cinch, great spring action, and outstanding durability. Plus, the trigger cables are protected by rubber tubing. I carried a Wired Bliss TCU on my rack for six years until someone stole it, and it's probably still going strong. The only real drawback to Wired Bliss units are their lack of cam stops.
Pros: Long stems; ultra-smooth spring action; rubber sheaths protect trigger wires; light.
Cons: No cam stops.
