With front and rear-specific profiles and an updated carbon layup, the Era 30 29in Boost Wheels are ready to rip in any terrain. Race Face designed the Era Wheels to be lateral and vertically compliant for a smoother ride and more traction. The front was tuned to be more laterally compliant, offering us an incredible 15mm of flex, while the rear is shaped to be more study while still deploying tons of vertical compliance. The Era rims feature a 30mm internal diameter and a wide 37. 2mm external diameter so we can run bigger tires with less pressure. Finally, Race Face slapped on their Vault hubs for ridiculous engagement and bombproof durability.
