How does the Exar Ultra DB508 compare to Zipp 808?

Both feature deep carbon disc construction; Zipp 808 has a longer track record and broader dealer support in India. The Ultra DB508 offers comparable carbon specification (HI-MOD rims and spokes) at significantly lower cost. Zipp's ABLC dimple technology and broader professional endorsement carry brand premium; Magene delivers the core performance at better value.

Can I upgrade the freehub body for different cassettes?

Freehub body replacement is possible on most quality hubs — confirm with InstaSport whether the Ultra hub allows Shimano HG to SRAM XDR swaps or vice versa, and whether this service is offered.

What rotor size is compatible?

Standard 140mm and 160mm Centrelock disc rotors are compatible. 160mm is recommended for road cycling for adequate heat dissipation on long descents in Indian mountain routes.
