xl gravel bike Pinarello Grevil F5 Rival AXS Gravel Bike

The Pinarello Grevil F5 Rival AXS is a gravel race bike for riders who approach an event's start list with the same intention they bring to its route profile. Pinarello has been building race bikes in Treviso since 1952, and the Grevil F platform carries that competitive heritage directly into gravel. The frame is built from Toray T700 UD carbon — not the T900 used in the top-spec F9, but a material that delivers a chassis light enough for long climbs and stiff enough to transmit effort efficiently on flat gravel roads. This is a competition-focused gravel bike that happens to be approachable; it isn't trying to do everything, but it does its specific job well.

Pinarello calls the design philosophy behind the Grevil F "Solo Dynamics" — an integrated approach to aerodynamics and storage built around long-distance solo racing. The most tangible expression of it is the down tube. Pinarello shaped it to maintain clean airflow around a 750ml water bottle, and inside the tube sits a built-in tool compartment accessible without pulling the bottle cage: sized for a mini pump, CO₂ cartridge, tire levers, and a TPU tube. That storage removes the need for a saddle bag, which in turn cleans up the rear of the bike and improves aerodynamics for solo efforts. The Fidlock frame bag completes the system — its magnetic attachment clicks into position without fumbling with straps, holds reliably over rough terrain, and releases quickly at service stops. For a rider planning a full-day effort, having tools and nutrition integrated into the bike rather than bolted on as an afterthought makes a real difference in how the bike handles and how quickly you can service yourself mid-race.

Compliance on the Grevil F5 is handled as a coordinated system. Pinarello's Adaptive Seatpost delivers 10mm of longitudinal flex, designed to absorb high-frequency vibration before it accumulates through an eight-hour ride. The Twin Arms seatstay configuration works in conjunction with the seatpost — the rear end flexes to maintain traction on loose gravel without sacrificing the lateral stiffness that converts pedaling into forward motion. Up front, the F Onda Fork carries Pinarello's signature curved fork profile. The current generation is lighter than its predecessor while preserving the compliance and handling character the Onda design is known for. The fork also includes ForkFlap, an integrated mudguard at the fork crown that deflects debris from the bottom bracket area — a detail that earns its keep on wet gravel roads and long days where surface spray is constant.

Drivetrain duties fall to SRAM Rival XPLR AXS, the wireless 13-speed gravel groupset. A 40t chainring paired with a 10-46t cassette covers a wide range — from loaded fire road climbs to flat gravel roads where you want a taller gear. Wireless eTap AXS shifting eliminates cable routing through the frame and removes mechanical adjustment as a mid-race variable. SRAM Rival hydraulic disc brakes with 160mm rotors provide consistent stopping with a lever feel that holds up to hand fatigue over long days. The MOST Gravel Carbon 45 wheelset runs on a 25mm internal hooked rim — deep enough for some aerodynamic benefit without becoming unpredictable in crosswinds. Vittoria Terreno T50 700x40 tires balance rolling efficiency on firm gravel with grip when surfaces get loose.

The cockpit is built around Pinarello's MOST component line throughout: the Jaguar XA GR TICR handlebar and Tiger ALU Aero TICR stem route cables and hoses internally through MOST's integrated cable routing system, keeping the front end clean without external bundles. The Most Lynx My26 saddle and MOST Ultragrip evo bar tape complete the contact points. Six frame sizes run from 47 to 60cm, covering a broad range of riders. The Grevil F5 ships in Namib Brown Matt — an earthy, quiet colorway that suits the bike's character and holds up well against long days in the field.
