Currently the company is expanding the offer of electronic gear shifting mechanisms and electric bicycle parts more and more. The range of products is not limited to bicycle parts, clothing for cyclists is offered as well.
HYPERGLIDE+ cassettes revolutionized off-road shifting with its seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling.
