Enduro riding demands quick power delivery out of rough sections as much as it demands a durable rim, and the Triad AL System Hydra2 Boost 29in Wheel pairs its impact-rated aluminum build with the Hydra2 System hub instead of settling for a basic hub underneath. That hub's 870 points of engagement at a 0. 41-degree pickup means the rim's durability doesn't come at the cost of instant response out of technical terrain. What Our Gearhead(R) Experts Are Saying:"Coming off a stalled-out climb over roots, I get back on the power before I'd even expect a slower hub to catch up, and that quick pickup matters more on enduro terrain than shaving grams off the rim."
