Syncros struck gold with their sublime Pro Series bottom bracket. While not the lightest on the market, it is robust and stylish with its colour coded gold and black lock rings.
The silver cups are beautifully machined from aluminium. The axle is hollow titanium. And lets not forget the 2 x 61903 (6903) top class SKF sealed cartridge bearings to keep you riding without bother for a very long time.
