Equipped with external slack adjustment, which can be done with a 2.5mm hex key through a hub shell access hole (can be adjusted without removing the wheel), and an improved plastic hub guard spec. The Clutch V2 is laced to the Odyssey Quadrant Rim. The Quadrant rim is made from 6061 T6 aluminium and uses a double wall design with one large hollow chamber through the middle for added strength. The Quadrant rim uses a unique pinned joint which uses 4 pins instead of the usual 2 to make a joint comparable in strength to a welded joint while saving costs. ###section### Product Specs WHEEL SIZE:20" HUB:Clutch V2 AXLE:14mm DRIVE SIDE:RHD/LHD Options RIM:Quadrant SPOKES:14 Gauge NIPPLES:Aluminum WEIGHT:TBC
