This Shimano GRX RX810 front derailleur is designed specifically for Shimano GRX cranks. With these cranks, there is a larger difference between the inner and outer leaf than with other cranks. The cage of this derailleur is therefore extended to allow for quick and smooth shifting on the Shimano GRX cranksets.
Newly designed cage
The newly designed cage allows for quick and smooth shifting with a difference of up to 17( teeth, between the inner and outer ring. It also allows you to shift the chain 2.5mm more than with Shimano’s race front derailleurs, making it easier to find the right gear.
Another advantage of the new design is the possibility of fitting wider tyres without the front derailleur rubbing up.
Require a derailleur clamp?Some bicycles do not have a braze on for the front derailleur. To mount this front derailleur, you can use a derailleur clamp.
