About the build

Pure Shimano throughout — no mixed components. Well-proportioned spec sheet with minimal tier variation across component groups. At Performance-tier, the drivetrain is among the best you see for the money here. Few gravel bikes reach this component level for less. The manufacturer doesn't publish geometry for this model, so we make no claim about fit or handling.
