If your ride comes down to the last climb, the wheel decides how much of your effort reaches the road. Our road wheels share one ART asymmetric rim design and come in three profiles: 35/40mm for climbing, 50/55mm for speed on the flat, and a 45mm endurance rim with 24mm inside width for wider tires at lower pressure. All are built for 27 to 33mm tires. Ninefold versions add carbon spokes and our own Onda-R Ceramic hubs for the lowest weight in each line. Start with the Avalon SL3, the Avalon SL5 or the Avalon 454 SL, or read our journal article on the lightest road wheels and climbing weight.
