Specialized's extra-stiff S-Works Team TT Chainring Set was originally designed for ProTour riders, with a CNC-machined profile and pick-up ramps for impressive shifting and power transfer. These aerodynamic rings are made of 7075 T6 aluminum, while the shift pins are riveted stainless steel and the chainring bolts are lightweight aluminum. They're compatible with 10- and 11-speed Shimano and 10-speed SRAM.
