Carbon wheels engineered to disappear beneath you.

Origin

Speed is engineered, not lucky.

We treat the wheel as a system, not a number on a scale.

Minimal rotational inertia turns every watt into immediate acceleration.

Philosophy 01

Engineered effortlessness

We obsess over grams so gravity feels optional.

Philosophy 02

Scientific precision

Every layup and spoke tension is validated by data, not guesswork.

The enthusiast's edge

We're riders building the gear we couldn't find.

Materials

Carbon, engineered to aerospace grade.

Built with Toray T1000 and T1100 carbon - aerospace grades that hit a strength-to-weight ratio road wheels rarely reach.

+40%

T1100 tensile strength over standard T700 - so we remove material, not confidence.

Integrity

Aerospace-grade layup

Flight-grade materials at the rim - maximum stiffness, minimum mass.

Compliance

Dynamic damping

T1100 and T1000 elongation absorbs impacts and damps vibration for high-speed stability.

Transfer

Zero compromise

Every watt meets a structure as resilient as it is light.

The property map

Where SIN sits on the Toray carbon map.

Every grade Toray makes, plotted by strength and stiffness. Up and right is better. The grades we build with - T1000G and T1100 - live in the aerospace frontier, far beyond the standard road-wheel field.

The maker

Built by the rider who needed them.

Every layup, spoke tension and rim profile is set by one person - a UK Audax randonneur who rides what he builds, and holds a doctorate in the science behind it.

PhD Mechanical
Engineering

The same materials science that validates aerospace structures decides where every gram lives. That is the edge: wheels engineered from first principles, not copied from a catalogue.

FAQ

Good to know.

Are the wheels tubeless ready?

Yes - both Feather One and Wavy One ship tubeless ready.

Disc or rim brake?

Feather One is available in disc or rim. Wavy One is disc only.

Freehub compatibility?

Is there a rider weight limit?

120 kg total system weight (rider + bike + kit).

Maximum tyre pressure?

120 psi.

What is the lead time?

4-8 weeks - every wheelset is built to order.

What warranty do you offer?

2 years.

Where do you ship?

Worldwide.

What is your returns policy?

Returns are accepted; return shipping is paid by the buyer.

How do I order?

Get in touch with your terrain, weight target and aesthetic, and we'll spec a wheelset around how you ride. Pricing starts from £1500.
