Coefficient Coanda Carbon UL31 Wheelset

$4,379.00 AUD $5,839.00 AUD

PLEASE NOTE: the Coanda wheelset ships from the USA. Delivery can take up to 14 days.

Coefficient's flagship carbon wheelset, the Coanda UL31 brings our core value of speed with comfort to road and gravel. It pairs the aerodynamic benefit of a deep carbon rim with the weight and crosswind stability of a shallow one, in a 28mm-deep profile that is at home on or off the tarmac.

The rim runs a 25mm internal, 31mm external hooked bed, tubeless-ready and built for tyre choice from road to wide gravel. Dependable DT Swiss 240 Centrelock hubs give fast engagement and reliable service, and easy-to-replace straight-pull spokes mean no hunting for obscure standards. At around 1,300g for the complete wheelset, it climbs as willingly as it cruises.

Available with a Shimano HGR or SRAM XDR freehub.

Who the Coanda is for

The Coanda is a one-wheelset all-rounder for riders who move between pavement and gravel and do not want to swap wheels to do it. The 28mm-deep rim carries enough profile to hold speed on the road, while the shallow-rim weight and crosswind manners keep it composed when the surface turns loose. It is the natural wheel partner for a Coefficient road cycling handlebars cockpit: comfort-first bars up top, a stable, tubeless-ready wheelset underneath.

Common questions

Which freehub options are available?

The Coanda is available with either a Shimano HGR or a SRAM XDR freehub, so it fits current 12-speed road and gravel drivetrains.

What tyre widths does the Coanda take?

The hooked rim runs a 25mm internal, 31mm external bed and is tubeless-ready. It is built for tyre choice from 25c on the road up to wide 50c gravel.

Why a hooked rim?

The 31mm external hooked bed adds tyre security and broadens tyre compatibility, so you can run a wide range of tubeless and clincher tyres with confidence.

How much does the wheelset weigh?

The complete wheelset is around 1,300g. It pairs the aerodynamic benefit of a deeper rim with weight and crosswind stability closer to a shallow one, so it climbs as willingly as it cruises.

How serviceable are the hubs and spokes?

The Coanda runs dependable DT Swiss 240 Centrelock hubs for fast engagement and reliable service, with easy-to-replace straight-pull spokes, so there is no hunting for obscure standards.

Where does it ship from, and how long does delivery take?

The Coanda wheelset ships from the USA. Delivery can take up to 14 days.

KEY FEATURES

Patented wing design delivers aero efficiency without the weight

31mm hooked rims for security and maximum tyre compatibility

DT Swiss 240 Centrelock Hubs

25mm internal width tubeless ready

Compatible with tyres from 25c to 50c

1300g wheelset weight

24 Unique Wing Profiles

The 24 unique wing profiles, honed through CFD and wind tunnel testing, create a low pressure area minimising the impact of the spoke as it encounters the oncoming airflow and controls the turbulent flow as it detaches from the wheel rim. At 20mph there is a 13% reduction in drag versus an equivalent standard profile 30mm rim and comparable with a much deeper section rim but at only 1300g for a complete tubeless ready wheel set.

Up to 50c Compatibility

Our pavement to gravel approach means tyre choice is all yours, from 25c to 50c the 25mm internal width provides a stable platform for whichever tyre size you choose for your ride, race or adventure. Hooked rims provide reassuring hold on your tyres however hard the terrain pushes back and being tubeless ready you can enjoy all the benefits of lower weight and rolling resistance. Plus we’ve tuned our carbon layup to minimise vibrations and when combined with our RR or AR bars it’s a recipe for all day comfort and speed.
