A great upgrade over a heavy stock OEM wheel, the Rouleur Disc offers a modern 21mm wide tubeless rim bed. All Prologue series wheels are built on Skyuka hubs featuring 10-degree engagement and Abec 3 sealed cartridge bearings. The Skyuka disc brake rear hub is available in a Shimano Hyperglide and Sram XDR freehub body and requires no tools to swap between the different freehub body standards. Built with Pillar TB2018 spokes and external brass nipples, the Rouleur is a great budget upgrade that can be used for everyday riding.
