Syntium R12 Hsp 12X Chainset

A modern chainset design utilising the HSP "High Stiffness Point" System, giving rigidity to the chainrings during the shifting process. The Syntium HSP uses a 4 arm spider design for crisp, clean looks but with the added rigidity of the HSP system, making them stronger than a 5 arm chainring. The HSP system strengthens the chainrings by using the spider to support them on both sides, without the use of spacers. All chainring bolts attach from the back of the crank, making them invisible when the chainset is fitted. * 12 Speed system * Shimano compatible * Rings: CNC'd AL 7075-T6 Total Treatment * Arms: Forged, CNC, Aluminium * BCD System: 110 HSP System * High Stiffness Point System * Weight: 860g
