Parts found in a manufacturer catalog show their brand, model and key numbers, and the steps show how precisely they are identified: brand, series, model, or the exact product. The info button has every detail and the text the manufacturer published.
Shimano GRX RX810, Gravel-specific derailleur with lighter operation and easier setup thanks to the new link construction and integrated cable tensioner., Max chainring gear range: 17T.
Canyon V13, High-quality aluminium stem with square cross-sectional profile. A new handlebar clamp design increases torsional stiffness by up to 40%. Handlebar clamp diameter: 31.8 mm. Head tube diameter: 1 1/4".
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.
2 sizes have no complete usable height range and cannot be checked.
