With 0.52 ° engagement, the brand new Industry Nine Hydra hub is 5.77 times quicker than its Torch hub

If you enjoy rolling through technical singletrack, you know having a quick engagement hub can make things much more enjoyable. You can ratchet your way through rocks and roots without hanging a pedal. Back in 2013, Industry Nine changed the hub game by introducing its Torch Series, a hub driver with 120 points of engagement.

They did it by combining a hardened steel 120-tooth drivering with six phased pawls, so only three touch the drivering at a given time. This results in very quick engagement – just three degrees at the crank.

Now, Industry Nine is rewriting the rules again with its Hydra hub. The new system takes a huge leap to a whopping 690 points of engagement, just 0.52 ° between each engagement. This results in essentially instantaneous engagement.

The new Hydra drive system does this by using an independently phased six pawl, 115-tooth drivering. This continuously phased system creates a procession of engagement points between pawl and drivering. The design utilizes the inherent flex of the axle to accomplish positive second, third, or fourth pawl contact. Hydra also tempers uncontrolled axle and bearing movements that conventional designs can’t mechanically limit, thus improving bearing life and decreasing resistance.

House votes to reauthorize FISA

After three failed attempts and what could only be described as a circus-like debate, the House finally managed to vote on Friday, approving a contentious program that gives US spooks carte blanche to eavesdrop without a warrant. The bill passed with a tally of 273–147, despite being about as
