Grand Cru 50.4 BCD Crankset
Classic 50.4 BCD cranks, like the TA, Stronglight 49D, and others, are still sought after by randonneurs and cyclo-tourists. These cranks offer tremendous versatility since chain rings from 28t to 62t fit. They are also light and have narrow Q-factors, or tread.
While the Grand Cru 50.4 Crankset looks like a classic, we have made several important improvements. They are cold forged from 7075 aluminum alloy. The rings are thicker so they don't flex as on classic cranks. The outer rings have modern shifting aids such as ramps and pins, so shifting performance is much improved. All stainless hardware with allen head nuts/bolts. Includes aluminum machined dust caps and BB bolts. Dust caps function as self extracting crank hardware.

These cranks are good value. They add a lot of versatility to a bike and get a lot more out of standard cassettes. I've used them on two builds with 8-speed drivetrains, but wouldn't hesitate to try them on other setups. They are probably the most solidly built cranks I've used. The chainrings feel very sturdy, and the finish is top-notch.
