Promax recently released the HF-3 Crank Set in 2023 with a super strong 30mm spindle! These aluminium cranks are hollow-forged from 6061-T6 aluminum, leading to a lightweight crankset. This combination is both light and stiff and backed with Promax's reputation for manufacturing affordable AND durable BMX race components.
A unique feature is that these cranks offer a direct-mount sprocket compatibility for additional weight savings, or run them with the included 104 BCD spider adapter. we would personally run them with the spider to make gear changes easier.Construction and features:
