Magene EXAR DB508 Ultra Dark Wheelset HG (2026)

The Magene EXAR DB508 Ultra Dark Wheelset HG (2026) is a disc‑brake‑only carbon wheelset engineered for riders who want a fast, stable upgrade for modern road bikes. Built around a distinctive lower front / higher rear rim concept (50mm front, 58mm rear), it aims to balance confident front‑end control with strong speed retention at the rear—ideal for fast group rides, rolling terrain, and windy conditions often experienced across Brisbane, Queensland and Australia.

The Ultra Dark series uses an integrated design approach with HI‑MOD T800 carbon fibre rims and spokes, paired with an upgraded hub and a 36‑tooth ratchet for quick engagement when you accelerate out of corners or surge up short rises. A modern 30mm external / 23mm internal rim profile is designed for today’s wider road tyres, especially 28–32c, improving comfort and stability while supporting a smoother tyre‑to‑rim transition for efficient aerodynamics in real‑world wind angles.

For riders upgrading key bike parts like wheels, tyres and tubeless setups, the DB508 Ultra Dark is best installed with professional bicycle service support to ensure correct rotor fitment, tubeless tape and valve setup, and freehub compatibility—especially if you plan to swap to SRAM XDR or Campagnolo N3W later.

Why riders choose the DB508 Ultra Dark

Lower front / higher rear rim profile (50/58mm)
Designed to keep steering predictable at the front while maintaining momentum at the rear when riding at speed.

Wide modern rim platform for 28–32c tyres
With 23mm internal width, the wheelset supports modern tyre volumes that improve comfort, grip and stability on rougher roads and long rides.

Full carbon spokes + 2:1 lacing for stiffness
Carbon spokes and a balanced lacing pattern are intended to reduce power loss and maintain a direct, responsive feel under load.

Fast hub engagement
A 36T flat ratchet provides quick pickup and a durable, large contact surface. A 54T ratchet option is noted as available separately.

Hooked rim for tubeless or clincher
Run tubeless for puncture resilience and lower pressures, or clincher with tubes for simplicity.
