AR25 TRA is as ready for a fast road ride on a 25mm tire as it is for an escape overnighter mounted on a bikepacking rig dressed in 40’s. If your dropbar disc brake bike sees duty on group road rides and long all-road adventures, keep the AR25 TRA on your short list.
24 HOLE 2/1 LACING PATTERN
Found on all of our road disc wheels. This lacing pattern reduces wheel weight and promotes even spoke tensions, while maintaining excellent durability. Rear wheels feature 16 spokes on the rear drive side flange, paired with 8 opposing spokes. Due to the rear wheel dish caused by the cassette on the rear wheel, this orientation evens out spoke tension. It also reduces peak stress loads on the spokes and rim, as well as the fatigue cycle incurred in a traditional 24 spoke wheel - allowing a lower spoke count and lighter weight, without the durability issues and increased rim weights commonly associated with low spoke count wheels.
Rated to withstand 700 ft/lbs of torque! We reduced the pawl count to 3 instead of 6, for lower drag and weight, while still achieving and industry leading (for road hubs) 6 degree engagement. Relocated bearings, and a new freehub seal reduce freehub drag while coasting.
Like all of our System Wheels, you can customize your hub and spoke colors in any combination for an additional fee. We offer 11 custom anodized colors: Orange, Purple, Turquoise, Lime, Gold, Green, Blue, Red, Pink, Silver and Black. Visit our AnoLab Custom Wheel Designer to customize your i9s.
