3. Components 3.1 rims 4ZA RC23 Aluminium rims are custom made by DT Swiss. By using a light weight doublewall construction and 18mm internal rim width, the overall stiffness is increased and they are perfectly suited for wider tires. This guarantees best-in-class performance and reliability. The rims also feature a Tubeless Ready profile which increases the tire choice. Tubeless Ready tires can be run at lower pressures for higher comfort and more grip, without the risk of pinch flats. The machined Aluminium brake track with Wear Control indicators will improve brake performance, both in dry and wet conditions. 3.2 hubs 4ZA partnered up with Shimano to provide their reliable RS400 hubs. Featuring the tried and trusted cup and cone bearing system with double seals, these hubs offer low rolling resistance and are fully compatible with 11speed cassettes. 4ZA WHEEL PASSPORT RC23 4

3.3 spokes The 4ZA RC23 wheels are assembled with high quality Mach1 Pro double butted spokes (2.0/1,7/2,0 mm). The variable thickness saves 25% weight while increasing the tensile strength. 3.4 nipples The 4ZA RC23 wheels are assembled with Mach1 nipples, which are a perfect match with the spokes. By using brass nipples we were able to increase the durability. 3.5 quick releases The 4ZA RC23 wheels come with Shimano cam style quick releases. The aluminium handle saves precious weight. 4. Art work The 4ZA RC23 wheels come with scratch proof vinyl stickers to increase the durability. 4ZA WHEEL PASSPORT RC23 5
