Is GRX better than tiagra?
In the upper range, the differences between successive sprocket sizes are greater in Tiagra. Therefore, with the GRX RX400, you’ll have access to much lower gears than Tiagra, but you won’t have access to higher gears. With a cadence of 90 RPM, it’s possible to achieve a speed about 50 km/h in the heaviest gear.
