The HARD series is UNAAS's more value-focused, durability-oriented line, designed for riders who want a genuine carbon rim without the added cost or delicacy of carbon spokes. The H50D uses Pillar 1423 steel spokes and steel bearings rather than the carbon spokes and ceramic bearings found on the Pro D50, which brings the weight up to around 1609g compared with the Pro D50's roughly 1460g. In exchange, you get a more affordable, robust wheelset that is generally more forgiving of rough roads and everyday wear, making it a great choice for riders new to carbon wheels or those wanting a dependable training and daily-riding wheelset. Both share the same 50mm rim depth and Winspace manufacturing standard, so the choice comes down to budget and how much you value carbon spokes and ceramic bearings.

The HARD H50D features a 50mm deep Toray T700 carbon rim with a 21mm internal and 27mm external width, weighing approximately 1609g for the complete wheelset, with a maximum system weight rating of 130kg. This depth and weight make it well suited to all-round road riding and everyday training, giving a useful aero benefit on flatter routes while remaining sturdy enough for regular use on typical Indian road surfaces. It is a great option for riders wanting their first carbon wheelset without stepping up to the lighter, more race-focused Pro series pricing.

Yes, the H50D is a disc brake specific wheelset intended for disc-equipped road frames, not rim-brake bikes. It is tubeless and clincher compatible, with a recommended tyre width of 25mm to 28mm and a maximum tyre pressure of 120 psi. Tubeless setups are a smart option for Indian conditions, where sealant helps guard against punctures from road debris and monsoon-season hazards. If you need a rim brake wheelset instead, UNAAS offers the dedicated HARD R40 for that purpose.

The H50D uses a 4-pawl hub system with steel bearings and Pillar 1423 steel spokes, laced 20 front and 24 rear with T-LOCK anti-rotation nipples, and is available with either a Shimano 11/12-speed and SRAM 11-speed compatible freehub or a SRAM XDR 12-speed compatible freehub, selectable at checkout. The freehub body is also noted as Campagnolo compatible depending on configuration, so riders on Campagnolo groupsets should confirm the exact freehub option with DoGoodCo before ordering. The rim currently comes in a single matt black finish with a white decal.

As with all UNAAS wheelsets manufactured by Winspace, the HARD H50D is covered by the same wheelset warranty terms Winspace applies to its own wheels, a 1 to 2 year manufacturer warranty against genuine manufacturing defects. This does not extend to crash damage, incorrect installation, or normal wear items such as bearings and spokes over time. Please retain your DoGoodCo order confirmation as proof of purchase, and reach out to our support team for any warranty claim so we can coordinate it with the manufacturer.

Yes, DoGoodCo sells genuine UNAAS wheelsets manufactured by Winspace, and every H50D is inspected before it is dispatched to you. Because UNAAS shares Winspace's factory and quality assurance process, you can be confident this is an authentic, factory-built wheelset rather than a copy or unauthorised import. This gives Indian riders reliable access to genuine Winspace-manufactured carbon wheels at an accessible entry-level price, backed by local support.

The H50D's steel spokes and steel bearings make it a fairly rugged wheelset for Indian conditions, but regular monsoon care will still keep it performing well for longer. Rinse mud and grit off the rim and hub after wet rides, keep the disc rotor interface clean, and periodically check spoke tension and the rim surface for any impact damage from potholes. Steel bearings are more tolerant of moisture than ceramic bearings but still benefit from periodic servicing, roughly every 6 to 12 months, especially if you ride frequently in high-humidity or waterlogged conditions. Drying the wheel down after wet rides and storing your bike indoors will help keep it in good shape for years.
