Shimano Tiagra ST-4720 Tiagra 2-speed STI bled with BR-4770 flat mount calliper, left rear

This brilliant set gives you more intuitive braking control, so you can tackle all the challenges of a long day out on the road. It features a lever with ergonomics inspired by the 105 series for greater comfort and actuation in all conditions. Easy to set-up, its reach adjust range is customisable to suit your hand size, type of riding and individual preferences. What's most impressive, is it gives you the same level of shifting operation as more high-end groupsets at an affordable price point. Enjoy the optimised low weight, high rigidity and heat dissipation of its caliper wherever the road takes you. This stunning model features oversized pistons which transfer hydraulic power directly to the brake pad for more efficient stopping power. Shimano has also carefully constructed it from ceramic material to avoid heat transfer for constant stable braking and high-performance even on long downhill stretches.
