Which bikes does the FitCrank fit?
FitCrank cranks are available in three standard lengths: 170 mm, 172.5 mm, and 175 mm. Other sizes can be produced upon individual request.
Before installation, ensure that the chosen length matches the length of the crank being replaced. Refer to the image on the side for how to measure the crank length correctly.
Installation is possible only on a BSA bottom bracket with a square taper mounting. This universal bottom bracket features a left-hand thread on the left side and a right-hand thread on the right side.
It comes in two variants:
- Traditional: most common in road bikes and stationary bikes, using the JIS system
-
Larger Square: found in some professional stationary bikes.
To determine whether your bike has a traditional or larger square taper, measure the width of the square. Refer to the image below for how to perform this measurement correctly.
