The Ridley Grifn A 105 2x12 embodies absolute versatility: an all-road bike designed to rack up miles on asphalt as well as gravel paths, with the Shimano 105 R7100 2x12-speed groupset and a triple-butted aluminum frame that is lightweight, stiff and accessible. Designed for demanding cyclists who refuse to choose between speed and adventure, this Grifn A offers all of Ridley's expertise in a modern chassis, equipped with 105 R7170 hydraulic disc brakes, KOG (Kanzo Optimized Geometry) geometry designed for endurance and 11 mounting points to customize your setup.

Technical Overview — High-Performance Aluminum and Complete Shimano 105 Groupset

Ridley selected a triple-butted 6061-T6 alloy for the Grifn A frame, guaranteeing excellent scores in stiffness, fatigue resistance, controlled weight and welding precision. Each tube is three times thinner in the center than at the ends: the triple-butted technique minimizes weight while maximizing stiffness in stress zones. The careful welds give the Grifn A a modern aesthetic and uncompromising durability. The 4ZA Allroad 7E7 carbon fork absorbs vibrations and ensures precise handling, while the Shimano 105 R7100 2x12 groupset — 50/34 crankset, 11-34 cassette — delivers a complete gear range for climbing, sprinting or riding at tempo on any terrain. The 105 R7170 hydraulic brakes with 2 pistons provide power, modulation and reliability in all weather conditions, with Ice Tech finned resin brake pads and a low-profile Flat Mount design.

KOG All-Road Geometry — The Best of Road and Gravel

• KOG (Kanzo Optimized Geometry): a clever balance between road frame reactivity and stability on rough terrain, with a 71.5-72° head angle and intermediate wheelbase (993-1021 mm depending on size) for lively handling without excessive nervousness.
• Progressive stack & reach: size M → stack 577-587 mm, reach 391-394 mm; comfortable endurance position for long rides, with a slightly higher stack height than a pure road frame to reduce fatigue.
• Short chainstays (420 mm): reactivity and liveliness when pedaling, while maintaining a bottom bracket drop of 73-75 mm to keep the center of gravity low and stability on descents.
• Generous tire clearance: up to 38 mm in 2x configuration, 40 mm in single-chainring 1x, or 34 mm with fenders — you can ride daily, go bikepacking or tackle cobbled sections with voluminous tires.

Modern Standards and Maximum Versatility

• Universal Derailleur Hanger (UDH): standardized SRAM derailleur hanger (Ridley HANUDHSRA001) — rare on an aluminum bike at this price point — facilitating replacements and offering future compatibility with direct-mount transmission groupsets.
• Integrated dynamo routing: cables for dynamo lighting run inside the frame, ideal for bike commuters and touring cyclists who want to ride safely at night.
• 11 mounting points: 3 on and under the downtube, 3 on the seat tube, mounts for fenders, racks and frame bag — configure your Grifn A as a bikepacking machine, urban commuter or pure training machine.
• Thru-axles 12x100 / 12x142 mm: increased stiffness, quick release and compatibility with all modern disc wheels.

Shimano 105 R7100 2x12 Drivetrain — Precision and Reliability

The Shimano 105 R7100 groupset is the benchmark for demanding cyclists seeking performance without budget compromise. With its 12 speeds to choose from, compact 50/34 crankset and 11-34 cassette, you have an ultra-complete gear range to handle steep climbs, sustained riding and explosive sprints. The 105 R7170 hydraulic shifter/brakes provide comfortable grip, adjustable reach adjustment and consistent braking power, regardless of terrain or weather. The 10% wider clearance range compared to the previous generation reduces disc rub and facilitates wheel changes.

Quality Equipment and Finishing

• Forza Stratos / 4ZA handlebar and stem: rigid and lightweight aluminum, compact drop geometry (70 mm reach, 122 mm drop) for ergonomic handling on road and gravel.
• Ø27.2 mm seatpost: classic round standard (Forza Stratos or DEDA Zero), 0-19 mm offset depending on variant, allowing precise position adjustment and compatibility with all aftermarket saddles.
• Selle Italia Model X / Model A saddle: comfortable performance profile for long rides, resistant composite shell.
• Vittoria Zaffiro Pro / EVO 700x30-32c tires: versatile folding tires, road performance and grip on dry paths; possibility to upgrade to tubeless for added comfort and reduced puncture risk.
• Glossy finish: quality gloss paint, clean welds and resolutely modern aesthetic.

Available Variants

The Ridley Grifn A 105 2x12 is offered in 6 sizes (XXS to XL) to suit all body types (approximately 152 cm to 198 cm). Several colors are available depending on markets:

• Chain Silver Grey/Black (GRA01AS): timeless sporty elegance, glossy finish.
• Dark Violet Cameleon/Silver (GRA01AS): modern chameleon shade with violet reflections, glossy finish.
