ZRACE RX Track Bike Fixed Gear Crankset 144BCD 46T-50T

ZRACE RX Track Bike Fixed Gear Crankset Design and Capability

The 144BCD bolt circle diameter establishes compatibility with a wide selection of track chainrings, allowing you to adjust gear ratios for different race distances without replacing the entire crank assembly. Chainring options from 46T through 50T suit various track cycling disciplines, whether you specialize in pursuit races requiring sustained power or sprint events demanding quick acceleration. Crank arm lengths spanning 165mm to 175mm accommodate diverse rider proportions and leverage preferences, ensuring your ZRACE RX crankset fits your biomechanics precisely. CNC machining throughout the crank structure creates rigid power transfer pathways essential for fixed gear racing where every watt converts directly into forward motion. This ZRACE RX track crankset combines modularity with precision manufacturing to support serious fixed gear cyclists and track racing competitors.
