Built on the same architecture as Rotor's 3D+ crank, the FLOW delivers genuine aero time savings — around 6 seconds over a 40km time trial at 200W — without the weight penalty and flex that compromise most dedicated aero cranksets.\u003c\/p\u003e\n\n  \u003cp\u003eThe aerodynamic case for the FLOW is grounded in how air actually behaves around a crankset in motion. By the time airflow reaches the crank, it has already been disrupted by the front wheel and fork — meaning the turbulent air at that point offers less resistance than calm laminar airflow would. Rotor's performance-focused arm profile exploits that environment rather than designing around an idealized wind tunnel scenario. The result is a crankset that functions equally well on an aero road bike or a dedicated TT and triathlon setup. Stiffness is maintained through Rotor's Trinity Drilling System — three full-depth holes drilled from axle to pedal eye — which resists both bending and twisting forces more effectively than conventional hollow-tube crank arm construction.\u003c\/p\u003e\n\n  \u003ch3\u003eRotor FLOW Aero Crankset Specs at a Glance\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003eAvailable BCD: 110mm (compact) or 130mm (standard)\u003c\/li\u003e\n    \u003cli\u003eCrank arm lengths: 172.5mm, 175mm, 177.5mm, 180mm\u003c\/li\u003e\n    \u003cli\u003eDrivetrain: 2x road\u003c\/li\u003e\n    \u003cli\u003eConstruction: Trinity Drilling System — three full-depth drilled channels for stiffness-to-weight optimization\u003c\/li\u003e\n    \u003cli\u003eCompatible with: TT, triathlon, duathlon, and aero road bike applications\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Rotor","offers":[{"title":"110bcd \/ No Color \/ 172.5mm","offer_id":43595157864492,"sku":"C02-051-20010-001","price":199.99,"currency_code":"USD","in_stock":false},{"title":"110bcd \/ No Color \/ 175mm","offer_id":43595157897260,"sku":"C02-051-21010-001","price":199.99,"currency_code":"USD","in_stock":true},{"title":"130bcd \/ No Color \/ 177.5mm","offer_id":43595157930028,"sku":"C02-050-22010-001","price":199.99,"currency_code":"USD","in_stock":true},{"title":"130bcd \/ No Color \/ 180mm","offer_id":43595157962796,"sku":"C02-050-23010-001","price":199.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/Rotor_Flow_Crankset3_c82a73a9-af55-4fef-b74b-0c24b0b578b7-643376.jpg?v=1737502197","url":"https:\/\/ricycles.com\/products\/rotor-flow-aero-crankset","provider":"RA Cycles","version":"1.0","type":"link"}
