Impact Eiffel Tower ISIS Cranks - 140mm (Silver)

Gone is the black finish we have seen for the past 10+ yrs. These cranks are now available in a beautiful polished finish with black inset details, a truly classy looking crank. The Outer profile has been kept the same but on the rear there have been a few changes. To improve the torsional stiffness of the crank the evenly machined pocketing depth has been replaced with a tapered pocket design. This provides stiffness where it is required and removes excess material that is not required. This has increased the weight by a few grams but the performance benefits out way the weight implications. As tested by multi times World Champion and World record holder Mike Taylor.

• Material: 6061 T-6 Aluminium.
• Colour: Polished silver
• Length: 140mm
• Weight (pair): 378g
• Type: ISIS
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.
