Is it really worth spending top dollar on a high-end front derailleur for a cyclocross bike, or can a more budget-friendly option get the job done just as well? Ive seen some riders swear by the Shimano GRX, while others claim the SRAM Rival is the way to go, but whats the real difference in terms of performance and durability? Are the extra features and technologies found in high-end derailleurs, like clutch systems and adjustable limit screws, truly necessary for cyclocross riding, or are they just marketing gimmicks? And what about compatibility issues - do the newer derailleurs play nicely with older frames and components, or is it a case of upgrade or be left behind?
