Your time on the bike is precious, let Shimano make it even better. Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO-WAVE technology. The Di2 platform untethers the shifters while delivering fast and reliable wireless shifting. The BR-R8170 hydraulic 2-piston disc brake caliper brings a new level of control to the road cycling world with improved modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.

Shipping for some reason took weeks to arrive. Item arrived after I needed it so it was no use to me.
Great unit, works as expected. Sierra was quick to deliver and easy to work with. Thanks!
Excellent helmet, nice colour and great performance. It is very fit ti the head.
Thank you !!!
Great softer materials but not the same support as the previous season. Pockets are large enough to fit stuff but the straps don’t support well. No chance you’re getting a water bottle in there. Also the bin straps position themselves right on top of your nipples. You’re going to notice that after an hour of pedaling and sweating.
I really liked the previous version so
Much that I wore 2 pairs out with 6000 miles. These new ones will be lucky to make it into rotation.
