ROTOR CRANKSET EMTB BOSCH EKAPIC ALLOY CRANKARMS QF171 BLACK 165mm (C02-119-17010-0)

SKU: C02-119-17010-0 Category:

Description

Rotor has designed the eKAPIC crank arms specifically for E-MTBs with a fourth-generation Bosch motor. They are made out of aluminium and, thanks to Trinity Drilling technology, are characterised by their low weight in relation to their stiffness. The low Q-factor of 171 mm ensures natural, knee-friendly pedalling that feels like riding a bike without electric drive.

Specifications:

Application:
Cross Country, All Mountain
Compatibility:
1x
Chainring Mount:
Bosch Direct Mount

Technical Information:

Series:
KAPIC
Crank Arm Material:
aluminium (6082)
Q-Factor:
171 mm
Recommended Bottom Bracket:
ISIS Drive

Compatibility:

  • E-Bikes with Bosch Gen4 motor
  • frame width (measured at a distance of 17 cm behind the centre of the crank axle) plus 4 cm (2 cm for each side) must be less than 17.1 cm (= Q-factor)

Features:

  • forged and CNC-machined aluminium
  • low weight with high stiffness
  • low Q-factor, similar to a bike without motor, for pedalling that is easy on the knees and hips

Technology:

Aluminium CNC
Computer Numerical Control (CNC) milling ensures a precise and uniform production process. This is particularly important when manufacturing components that must function properly and work in congruity with other parts. Thanks to state-of-the-art CNC equipment, Rotor parts are manufactured with extreme precision, down to a hundredth of a millimetre.

TDS
Rotor CNC cranks have a particularly high stiffness due to the Trinity Drilling System (TDS). In this procedure, three full holes are drilled from the bottom bracket to the pedal. This creates a box-like grid, similar to a box girder bridge. This makes the cranks extremely stiff while at the same time reducing weight, resulting in an excellent stiffness-to-weight ratio.
