Lún MEGA D45

Weight1375g
CategoryWheels

The Lún MEGA D45 is a high-stiffness, one-piece carbon wheelset with a unique replaceable spoke system, praised for its aerodynamic performance and light weight but criticized for its high price, harsh ride, and significant quality control issues reported by multiple reviewers. It is best suited for racers on smooth roads, though the risk of manufacturing defects and proprietary repairs may deter some buyers.

Pros

  • Very stiff laterally and torsionally, among the stiffest wheels tested, beneficial for racing and out-of-saddle efforts.12
  • Lightweight: measured 1389g (GC Performance), 50g lighter than D45 (Peak Torque), lighter than Hyper wheels by a few grams (Cyclists Hub).312
  • Innovative Halo spoke system allows for spoke replacement, unlike other one-piece wheels.32
  • Aerodynamic performance comparable to CRW wheels in aero tests.1
  • Quiet braking in wet conditions, no brake squeal.1
  • Easy tubeless tire installation without tire levers; tubeless tape and valves pre-installed.2
  • Good weather sealing on bearings.1
  • Includes accessories: saddle bag, tire levers, valve extenders.3
  • Relatively affordable compared to Western alternatives like Lightweight Meilenstein.2

Cons

  • High price at $2600 USD, though discounts available.312
  • Quality control issues: bolts holding flange came loose (not Loctite'd), rear hub off-axis causing disc rub and sensor error due to iron fillings.12
  • Very stiff, leading to harsh ride on rough roads; requires lower tire pressure (e.g., 60 PSI or less) to compensate.12
  • Spoke replacement is difficult and proprietary: must replace one whole side of spokes with proprietary hubs.2
  • Only available in one rim depth combination (46mm front, 54mm rear) and one color (white).3
  • Weight saving over original D45 is only about 50g, which may not justify the price increase.3
  • Heavier than some cheaper alternatives like Elitewheels Drive 45mm.2
  • Rim profile and look very similar to cheaper Winspace D45 Hypers, lacking a unique premium look.3

Key Facts

  • Weight: claimed 1375g ±25g, measured 1389g with one tubeless valve (GC Performance); front 616g, rear 782g (Cyclists Hub); 50g lighter than D45 (Peak Torque).321
  • Price: $2600 USD, with discount codes available (e.g., GCperformance10, cyclup10 for 10% off).32
  • Rim dimensions: 46mm front, 54mm rear depth; internal width 20.8-21mm, external 28-28.1mm; hooked rim system.312
  • Halo spoke system allows replaceable spokes and hub flange, but replacement requires replacing one whole side of spokes with proprietary hubs.32
  • Hub features: ratchet system (36-tooth) similar to DT Swiss, ceramic bearings, high preload, anodized axles, square drive.31
  • Designed for 25mm and 28mm tires; tubeless tape and valves pre-installed.2
  • Bolts holding the flange are T25 socket, M5, countersunk; not Loctite'd from factory, leading to loosening.1

Engineering Marvel or Marketing Gimmick? Lún MEGA Wheels Review

The reviewer, Peter from cyclup.com, provides a detailed review of the Lún MEGA D45 carbon wheels, highlighting their exceptional stiffness due to patent-pending Halo spokes, but also revealing a serious manufacturing defect in the rear hub that required a warranty replacement. He notes they are among the most expensive Chinese wheels at $2600, best suited for racers on smooth roads, and not for everyone due to high stiffness and repair difficulties.

Winspace Lun MEGA review - Are Chinese brands leading Wheel development? #cycling #carbon

The reviewer discusses the Lún MEGA D45 wheels, noting they share the same rim as the D45 Gen 2 but feature a proprietary hub system that provides extreme stiffness. He highlights their aerodynamic performance, low weight, and quiet braking in wet conditions, but also mentions concerns about ride comfort due to stiffness and a quality control issue with loose bolts.

*WINSPACE MEGA D45* WILL THESE WHEELS CHANGE THE INDUSTRY??

The reviewer discusses the Lún MEGA D45 wheelset, a carbon fiber wheelset with a one-piece design but replaceable Halo spokes.

He notes the price of $2600 and compares it to other high-end wheels, considering it a good entry-level option for one-piece wheels.
