Although both the Pro D50 and the HARD H50D share a similar 50mm rim depth, they sit at different tiers within the UNAAS range. The Pro D50 uses lightweight 5.0mm carbon spokes and NBS ceramic bearings, giving it a lower overall weight of around 1460g and a more refined, race-oriented ride feel. The HARD H50D, by contrast, uses steel spokes and steel bearings, making it noticeably heavier at around 1609g but more budget-friendly and robust for everyday riding. If outright performance and low weight matter most to you, the Pro D50 is the better choice, while the HARD H50D suits riders prioritising value and durability at the same rim depth.

The Pro D50 features a 50mm deep Toray T700 carbon rim with a 21mm internal and 27mm external width, weighing approximately 1460g plus or minus 50g for the complete wheelset, with a maximum system weight rating of 130kg. This deeper 50mm profile makes it a strong all-round aero road wheelset, giving a noticeable aerodynamic advantage on flatter rides and fast group rides while still being manageable on rolling terrain typical of many Indian cycling routes. If you want a shallower, slightly more climb-friendly option from the same Pro line, our UNAAS Pro D40 offers the same build quality at a 40mm depth.

Yes, the Pro D50 is a disc brake specific wheelset built for modern disc-equipped road frames and is not designed for rim-brake bikes. It is fully tubeless and clincher compatible, with a recommended tyre width of 25mm to 28mm and a maximum tyre pressure of 120 psi. Running tubeless is a smart choice for Indian roads, where sealant can seal small punctures on the go, reducing the chance of a flat during monsoon or debris-heavy conditions. If you specifically need a rim brake wheelset, UNAAS also offers the dedicated HARD R40 rim brake model.

The Pro D50 uses a 36-tooth ratchet hub system with NBS ceramic bearings, and it is available with a Shimano 11/12-speed and SRAM 11-speed compatible freehub body or a SRAM XDR 12-speed compatible freehub body, selectable at checkout. The 5.0mm carbon spokes are laced 24 front and 24 rear, and the rim is offered in UD black finish, black and grey decal, or arctic white, so you can also choose your preferred aesthetic when ordering. Be sure to select the freehub option matching your groupset before completing your purchase.

As UNAAS wheelsets are manufactured by Winspace, the Pro D50 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 in the rim, spokes, and hub. This does not cover crash damage, incorrect installation, or wear items such as bearings and rotors over normal use. Please retain your DoGoodCo order confirmation as proof of purchase and contact our support team for any warranty claim so we can handle it with the manufacturer on your behalf.

Yes, DoGoodCo sells genuine UNAAS wheelsets manufactured by Winspace, with each Pro D50 inspected before dispatch. Because UNAAS shares Winspace's manufacturing lines and quality assurance, you are getting an authentic factory-built wheelset rather than a copy or unauthorised import. This gives Indian riders confident access to genuine Winspace-grade carbon wheels backed by local support from DoGoodCo.

The Pro D50's carbon spokes and ceramic bearings handle Indian conditions well with a bit of monsoon-specific attention. Rinse off mud and grit after wet rides, keep the disc rotor interface and hub seals clean, and periodically check the rim edges and spokes for damage after riding through potholes or debris. Ceramic bearings are sensitive to water ingress, so avoid direct high-pressure washing near the hub, and have them serviced roughly every 6 to 12 months, more often if you regularly ride through waterlogged streets. Drying the wheel down after wet rides and storing your bike indoors will help preserve both the rim finish and the bearing life.
