2009 Shimano Dura-Ace FC-7900 B-type crank set 39T/53T 170.0 mm double 10-speed

Frame and Wheel is auctioning a 2009 Shimano Dura-Ace 7900 Hollowtech II road crank set on the Frame and Wheel eBay Store. The crank set was originally installed on a Cervelo S2 road bike that was purchased new in February 2010. The crank set was switched out in August 2011 and replaced with a compact. It has been in storage since then. It has about 600 hours of all weather racing and training on it. Frame and Wheel is the original and only owner of the cranks and is selling them because Frame and Wheel has upgraded to an Austro-Daimler Superlechit Carbon Di2 and no longer needs these cranks. The crank set features standard road gearing, a hollow outer chain ring and gray / black lettering finish. The crank set is in fair condition and shows signs of wear. The teeth on the outer chain ring are beginning to look like shark fins. The teeth on the inner chain rings are narrowing. There is wear on the drive-side and non drive-side crank arm from a bootie. Nevertheless, the chain rings are not bent and the teeth are not chipped or broken. All the chain ring bolts and crank arm fixing bolts, caps and washers are included. The bolt holes for the pedals and the crank arms are not stripped. There is no corrosion anywhere on the cranks set. The splines are not stripped or damaged. These crank sets are no where near the end of their useful life, but they are not exactly new either. They have a bright future on a winter training bicycle, a cyclocross bike or a commuter bike, or perhaps the new owner can replace the chain rings.
