Impact Eiffel Tower ISIS Cranks - 140mm (Black)


This generation of Eiffel Towers take over from the where the excellent previous generation crank left off. The broader section gives a greater landing area and increased strength without increasing the overall width.

The latest generation of Eiffel Tower ISIS unicycle Cranks are deep pocket forged and CNC machined to optimize stiffness and strength. Eiffel Towers are an incredibly light & stiff performance crank set for today's riders for Trials riding. Quite possibly the most versatile crank set you will ever own.

Pedal washers go between the pedal and the crank, helping to increase the life of your cranks. Plus, ensuring maximum contact between both (keeping your pedals tight). We recommend pedal washers for all aluminium cranks.

These cranks are specifically designed for Trials riding. The length of the crank makes for far superior balancing ability over shorter or longer cranks.

Material: 6066 T-6 Aluminium.
Color: Gloss Black
Length: 140mm
Weight (pair): 367g
Type: ISIS
Pedal szie: 9/16"
Q-Factor: Almost Zero Q-factor - This is the amount a crank bends outwards. Zero means it doesn't lean outwards at all. The straighter the crank the better for speed, the wider the better for ankle clearance and greater manoeuvrability.

Note: Crank length is measured from the centre of the axle hole to the centre of the pedal hole. Sold in pairs.
