What our customers are saying about Shimano Ultegra Di2 ST-R8170/BR-R8170 Front Brake

This original Shimano Ultegra Di2 ST-R8170 brake set delivers exceptional, high-quality performance comparable to the top-tier Dura-Ace groupset. The 12-speed system is praised for its quick and easy setup. The product is a complete front or rear brake kit, including the ST-R8170 lever, BR-R8170 caliper, and necessary hoses for a full installation

Brake lever

adriano-

The Ultegra lever works wonderfully. I've had the group for three years and well, I don't know what could have happened, and better than the left lever working, it's there and it works perfectly. It has to be a problem as can happen with other things, but what happened is strange because I've had other electric groups and I've never had any problems and I'm almost sure that I won't have any more with these levers.

Great deal…

Works like Dura-Ace, the only difference is in the materials.

Is this product available with a right hand lever for the front brake. We have opposite sides for levers in Aus.

You can simply swap the hydraulic lines between the calipers. Connect the right lever to the front brake and the rear brake to the left lever
