The EXAR DB405 UltraDark takes Magene's carbon-spoked Ultra platform and finishes it in a dark black look that suits almost any frame, with a 40mm front and 45mm rear rim for fast, stable riding.

Highlights

  • 40mm front / 45mm rear HI-MOD T800 carbon rims
  • HI-MOD carbon fibre spokes, 2.8g each
  • 36T flat ratchet (54T available separately)
  • 1305g per pair (±3%)
  • 30mm external / 23mm internal width, hooked rim
  • Tubeless or clincher, 25c and up (28-32c suggested)

Lower front, higher rear

A shallower front rim keeps handling predictable in crosswinds, while the deeper rear rim adds aero benefit where it is least affected by wind.

Carbon spokes, stiff hubs

HI-MOD carbon spokes in a 2:1 balanced lacing pattern run at 130kgf ±10% drive side and 110kgf ±10% non-drive side on the rear. The hubs use standard bearings and a 36-tooth flat ratchet, which can be swapped for Magene's 54T ratchet.

Built for wider tyres

The 30mm external and 23mm internal rim width suits 28-32c tyres, creating a smooth tyre-to-rim transition for aerodynamics and comfort.

Compatibility & fit

Disc brake only, for 100mm front and 142mm rear thru-axles. Supplied with a Shimano HG 11-speed freehub; Campagnolo N3W and SRAM XDR freehub bodies are sold separately. Hooked rim, compatible with tubeless and clincher tyres from 25c (28-32c suggested). Maximum system weight (rider plus bike) is 110kg. Wheel set-up, tyre fitting and tubeless set-up are available from our workshop as a separate service, not included in the price.
