At Velogear, we're all about bikes. We love riding them, reading about them and fixing them. And when bikes are on TV, we love watching them. We want to make it easy for you to indulge your love of cycling, too. We stock cycling clothing from the best brands in the sport, along with books, DVDs, parts, accessories and more. We want to be your one-stop shop for all things cycling!
Shimano's Dura-Ace 11-speed Cassette is comprised of two aluminum cog carriers, 5 titanium and 6 steel cogs (from largest to smallest respectively). This makes for a super-light and stiff cassette for perfect shifting so you can dance up the climbs as easily and efficiently as your chain climbs up and down these cogs.
