Here we have a BSD Revolution Freecoster hub laced into a lightweight Aero Pro rim. The BSD Revolution Hub is a next-generation Planetary freecoaster, it's a hub that feels like a cassette hub, weighs the same as a cassette hub, has a pedal gap like a cassette hub and sounds like a cassette hub. Despite its looks the The Aero Pro is super strong thanks to extra thick tapered sidewalls, angled spoke seats designed to accommodate proven cross-over lacing and a curved inner strut. It also has two intra cavity supports further increasing the radial stiffness and axial strength. The wheel also comes with hub guards so if you're looking for a bullet proof freeecoaster wheel then look no further! ###section### Product Specs WHEEL SIZE: 20" HUB: 14mm Sealed Freecoaster AXLE: 14mm Male DRIVE SIDE: Available in RHD and LHD RIM: Aluminium Rim With DoubleWall SPOKES: Straight Gauge NIPPLES: Brass WEIGHT: 1100g Colour: Black; Size: LHD
