In Race Face's own words, the Aeffect 27. 5in wheelset was designed to be a hardworking, no nonsense set of hoops. Already known for solid, reliable drivetrain kit, Race Face has only recently entered the wheelset category, introducing a wheel for everyday XC and trail miles that further burnishes the company's sterling reputation for bombproof ness. With a claimed weight of 1,820g, the Aeffects don't break any records for their lightness, but they also won't empty your wallet the way some of their featherweight compatriots will. To give the wheels stiffness and durability without the price tag of carbon, Race Face uses treated 6061 aluminum to construct the rims. They feature a generous 23mm internal width and 27. 3mm external width with a depth of 20. 5mm. They're laced with 28 straight pull, bladed spokes in a cross laced pattern to achieve a stiff and snappy response as you corner and climb on singletrack. The hubs feature Race Face's sturdy, custom sealed cartridge bearings and 3 pawl design to offer fast and reliable engagement across 21 points.
