Determine the optimal frame size for your Single Speed & Fixed Gear
1. Measure step length
Please measure your inside leg length from the sole (without shoes) to the crotch.
Depending on body size and sex, the crotch length of an adult is between about 65 cm and 95 cm.
2. Calculate the frame size
Enter your step length in cm:
If the calculated value is between two frame sizes
- For a more agile, sporty driving experience choose the smaller bike
- For a more quiet, touring-oriented experience choose the larger bike
Tip:
The frame size refers to the length of the seat tube from the middle of the bottom bracket housing to the upper edge of the seatpost. For a triathlon bike, choose the frame size approximately 3.5 - 4 cm lower.
Don't have a tape measure?
