OVERFAST Ultralight Seatpost Dust Cover – Factor ONE

Because Every Gram Counts.

OVERFAST has taken one of the smallest components on the new Factor ONE and asked a simple question:

Can it be lighter?

The answer is yes.

Designed as a direct replacement for the original Factor ONE seatpost dust cover, the OVERFAST version uses advanced 3D-printed construction to reduce weight from approximately 7.7g to just 1.8g.

That's a saving of 5.9g — approximately 77% lighter than the original part.

Tiny component. Serious attention to detail.

1.8 Grams

There's lightweight.

And then there's OVERFAST.

At approximately 1.8g, the replacement dust cover removes almost three quarters of the weight of the original component.

Original: approx. 7.7g
OVERFAST: approx. 1.8g
Weight Saving: approx. 5.9g
Reduction: approx. 77%

Will 5.9 grams transform your bike?

No.

But when you're building a bike where every component has been considered, these are exactly the details that add up.

3D-Printed Construction

The OVERFAST dust cover uses a lightweight 3D-printed structure, allowing material to be used only where required.

The result is an extremely low-mass component that retains the shape and function required of the original seatpost dust cover while stripping away unnecessary weight.

A simple component, completely reconsidered.

Designed for the Factor ONE

This isn't a generic seatpost cover.

It has been developed specifically as a replacement for the new-generation Factor ONE, following the profile of the original component and sitting neatly around the aerodynamic seatpost.

Simply remove the original cover and replace it with the OVERFAST component.

The Details Add Up

A seatpost dust cover isn't going to win you a race.

But that's not really the point.

The pursuit of a truly lightweight build comes from looking at every component, including the parts most people would never consider changing.

5.9 grams here.

A few grams somewhere else.

Keep going and suddenly the numbers start to become significant.

That's the OVERFAST approach.

1.8 grams.

Because every gram counts.
