The UNAAS Pro line, including this Pro D40, sits at the premium end of the range, built with lightweight 5.0mm carbon spokes and NBS ceramic bearings for a faster, lighter ride feel. The HARD and HARD2 series are UNAAS's more value-focused, entry-level wheelsets, typically built with steel spokes and steel bearings instead of carbon spokes and ceramic bearings, trading a small amount of weight and refinement for a lower price and added everyday durability. If you want the lightest, most race-oriented ride in the UNAAS range, the Pro series is the one to choose, while the HARD and HARD2 models suit riders who want a robust, dependable carbon wheelset as their first step into carbon. If you are unsure which tier fits your riding style, our team at DoGoodCo is happy to help you decide.

The UNAAS Pro D40 features a 40mm deep Toray T700 carbon rim with a 21mm internal and 27mm external width, and the complete wheelset weighs approximately 1396g plus or minus 50g with a maximum system weight rating of 130kg. This shallower 40mm depth makes it a versatile all-round road wheelset that climbs well while still offering a useful aero benefit on flatter rides, making it a great match for mixed-terrain Indian routes with climbs and descents. If you want a deeper, more aero-focused wheelset for flatter racing and time trial use, the UNAAS Pro D50 in our range offers the same build quality with a 50mm rim depth instead.

Yes, the Pro D40 is a disc brake specific wheelset designed for modern disc-brake road frames and forks, and it is not intended 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. Tubeless setups are especially useful on Indian roads, where sealant can help seal small punctures from glass, thorns, or monsoon debris without stopping your ride. If you specifically need a rim brake wheelset, note that UNAAS also offers the HARD R40, which is a dedicated rim brake model rather than disc.

The Pro D40 uses a 36-tooth ratchet hub system with NBS ceramic bearings for low rolling resistance, and it is available with either 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 spokes are 5.0mm carbon with T-LOCK anti-rotation nipples, laced 20 spokes front and 24 rear, and the rim is offered in either a UD black finish or a black and grey decal option. Make sure to choose the freehub option that matches your groupset, Shimano/SRAM 11-speed or SRAM XDR 12-speed, when placing your order.

Since UNAAS wheelsets are manufactured by Winspace, the Pro D40 carries 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 warranty does not cover crash damage, incorrect installation, or normal wear items like bearings and brake rotors over time. Keep your DoGoodCo order confirmation as proof of purchase, and contact our support team for any warranty claim so we can process it on your behalf with the manufacturer.

Yes, DoGoodCo imports and sells genuine UNAAS wheelsets, manufactured by Winspace, with each Pro D40 inspected before it is dispatched to you. Because UNAAS shares Winspace's manufacturing lines 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 direct access to genuine Winspace-grade carbon wheels at accessible pricing, backed by local support from DoGoodCo.

The Pro D40's carbon spokes and ceramic bearings perform excellently on Indian roads, but a bit of monsoon-specific care will extend their life. Rinse off mud and road grime after wet rides, keep the disc rotor interface and hub seals clean, and inspect the rim edges and spoke nipples periodically for damage from potholes or debris. Ceramic bearings are sensitive to water ingress, so avoid direct high-pressure jet washing near the hub, and have the bearings serviced roughly every 6 to 12 months, more often if you ride frequently through waterlogged streets. Drying the wheel down after monsoon rides and storing the bike indoors will also help preserve the rim's finish over time.
