Flow - TT crank time savings with road crank rigidity

The flow, based on our 3D+ crank, is a paradigm-changing aero crankset; designed for both Road Aero and pure TT bikes. It offers the time savings of classic aero cranks and the performance of leading road cranks, all at once.


Our focus on stiffness and functionality, allow the Flow to match and even beat full aero cranks in the real world.



Avoids the pitfalls of many aero cranksets

Giving a 6 second time reduction on a 40KM TT or 15 seconds over an IM bike split, at 200W average power, the Flow’s construction avoids the pitfalls of many aero cranksets: Compromised performance in the form of added weight and flexibility, as well as a look that doesn’t fit with aero road bikes.



Real world performance - Less resistance to wind

This is possible because a crank does not meet fully laminar airflow while riding: A bike’s front wheel and fork have already sliced through the air that hits the crankset. This turbulent air offers less resistance than calm air, allowing our performance focused Flow design to excel.



This makes the Flow not only a fully-fledged TT, Triathlon and Duathlon worthy crank, but a credible and coherent upgrade to further the performance of aero road bikes, as proven by professional teams such as Garmin Sharp Barracuda that use of the Flow on their aero road and TT bikes.


Trinity Drilling System - Bombproof design and reliability

ROTOR's bombproof trinity drilled crank arms resist bending and twisting forces better than classic hollow tube crank designs can. ROTOR’s crank arms are stiffer than the competitions forged products due to our Trinity Drilling System. This process drills three full-depth holes from axle to pedal, leaving behind a boxtrellised structure (similar to box bridges). This gives our crank arms superior rigidity and an exceptional stiffness-to-weight ratio.


Universal Bottom Brackets - It works with everything!

The UBB (Universal Bottom Brackets) system is not a standard; It’s all standards. It allows installation of almost any 30 or 24mm axle crank from ROTOR on the bike you have, regardless of its BB type. ROTOR’s “UBB” super-standard encompasses all BB standards.



Solutions. That’s probably the best word to describe ROTOR’s design philosophy. We identify performance problems and set out to solve them, resulting in improved & optimized products.


Twin Leg Concept

  • TLC or Twin Leg Concept creates the best, most balanced cranksets.


ALMA

  • Appropriate Light Weight Material Application or ALMA also means "soul" in Spanish.


Micro Adjust Spider - More positions to suit every rider´s needs

The new Micro Adjust Spider (MAS), offers more positions to suit every rider’s needs. Our new advanced MAS spider has an alternative bolt hole placement allowing for intermediate positions between existing OCP (Optimum Chainring Position) of the Q-Ring. A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment.



The MAS spider when used with Q-Rings offers half positions giving approximately 2,5 degrees. This means that you can micro adjust the position of your Q rings, to suit your riding style.


Every option

Available as an option in 3D+ range in road 130 & 110 BCD cranks, and in mountainbike XC2 cranks. POWER and FLOW cranksets only use MAS spiders.


The OCP allows you to pedal comfortably in all cycling positions:

  • Sitting
  • Standing
  • Climbing
  • Sprinting


Features

  • 542 g for 170 mm / 552 g for 175 mm
  • 170, 172 & 175 mm
  • 100% CNC machined, T6 7075.
  • Aero MAS spider, allowing finer Q-Ring setup.
  • 148 mm Q-Factor, 43.5mm Chain line.
  • Ultra stiff 30 mm Aluminum UBB axle; compatible with BSA, ITA, BB86, BB30, BB30 PF, BBRight and BB386 Evo frames.
  • For all 110 BCD 10&11 speed, oval & round chainrings.

Occasionally, without notice, manufacturers change product design and/or specifications.
