Shimano Tiagra RD-4700 Front Derailleur
And there are few places you're more likely to notice that than in the redesigned front derailleur. One of the best advancements of Dura-Ace 9000 and Ultegra 6800 were the redesigned front derailleurs with the longer lever arm. Well, that new technology has founds it's way to Tiagra 4700. So what does that mean? The new longer lever arm means that you get the shorter lever throw the new generation of Shimano is known for, but with massively improved leverage and more powerful front shifting. That means that your new Tiagra front derailleur can shift up to the big ring with less effort and more precision, even under power. It's just part of what makes Tiagra 4700 a worthy upgrade to your road bike, or a great option for a new commuter, winter bike, touring bike, or CX bike.
