The Eclat Cortex Temple front wheel is built using a 36H Eclat Temple double-wall rim laced 3X with black 14G spokes and nipples to a Eclat Cortex front hub. The Eclat Cortex front hub features a strong, grind friendly design. It uses a 6061-T6 aluminum shell and includes two integrated nylon hub guards to protect the spokes from grind damage, two sealed bearings, a 4130 chromoly axle, and two 3/8" chromoly bolts.
