Technology:

HYPERGLIDE+ technology is an innovation in bicycle gear shifting, making the process extremely smooth whether increasing or decreasing gears. Initially adapted for mountain bikes, allowing riders to change gears without any disruption even on challenging trails. Now, HYPERGLIDE+ comes to road cycling, giving cyclists the ability to change gears without the need to lessen pressure on the pedals, even when intensely climbing or racing against a friend.
