The F5 sits below the X7 in Pinarello's lineup — T700 fiber rather than T900, and competition geometry rather than Endurance+. This means a lower stack, longer reach, and a position oriented toward performance rather than all-day comfort.\u003c\/p\u003e\n\u003cp\u003eThe 50cm F5 ships with a \u003cstrong\u003eShimano 105 R7170 hydraulic disc brake system\u003c\/strong\u003e (160mm rotors front and rear), MOST Jaguar Claw aluminum bar\/stem cockpit, MOST Lynx saddle, and MOST Competition 700x30mm tires. Maximum tire clearance is 32mm.

The 12-speed cassette provides a usable climbing gear without requiring a wide-range setup.
