This selection of wheels covers three specific hub configurations for modern mountain bike standards. The front wheel uses a 15x110mm thru axle spacing for standard trail forks. Rear wheel options include a 12x148mm thru axle with either a HG driver for 8 to 11 speed drivetrains or a Microspline driver for Shimano 12 speed systems. Each wheel uses the Center Lock disc interface.

The WTB ST i30 rim provides a stable platform with a 30mm internal width for wide tire profiles. These wheels feature 32 Sapim stainless steel spokes and brass nipples for a durable construction. The Shimano hubs include sealed cartridge bearings and labyrinth seals to maintain performance in muddy environments. Every wheel includes the TCS 2.0 Solid Strip for a reliable tubeless setup.
