"Hope's new cassette with integrated freehub. Designed to be retro-fitted to the company’s highly regarded Pro 2 and Pro 3-hubbed wheels, this new cassette incorporates the freehub body and sprockets in one neat little package.
According to Hope, a Pro 2 wheel with Hope cassette works out 20g lighter than with a freehub and SRAM's top-end XX sprockets fitted.
On the 10-speed version seen here, the five inner (green) sprockets are machined from a single piece of aluminium, while the five outer (gold) ones are made of steel, and will be coated with titanium nitride on production models. Expected to hit shops in early 2011, the new cassette will sell for around £150. "
"Hope have created their own chainguide, machined in-house from 2014 aluminium. Chainrings should be available to match in spring 2011"
