ZTTO markets this cassette at approximately 198 grams, noticeably lighter than their full steel 11-34T cassette, thanks to the aluminium cogs used on the larger sprockets. Exact weight can vary slightly batch to batch, as with most manufactured components, so treat this as a close approximation rather than a lab-certified figure. If precise weight matters for your build, we're happy to share the latest available spec details before you order.

Aluminium cogs are inherently softer than steel, so this cassette trades some outright longevity for a meaningful weight reduction, similar to the aluminium-alloy cassettes used across the performance cycling market. ZTTO offsets this by keeping the most frequently engaged, highest-wear cogs in steel, concentrating aluminium on the larger, lower-wear cogs instead. For racing, climbing-focused riding or lighter riders, this tradeoff is usually well worth it; for high-mileage daily commuting in gritty conditions, the standard steel cassette may last longer.

This 12-speed 11-34T cassette is built around the standard HG-pattern freehub spline used on most Shimano 11-speed style freehub bodies fitted to road and gravel wheelsets in India. If your bike uses a SRAM XD or XDR driver, please confirm compatibility before ordering, since those hubs need a differently splined cassette. We're happy to help verify fitment if you share your wheel or hub model with us.

Yes, 11-34T offers a solid low gear for climbing while the reduced cassette weight further benefits riders focused on hill climbs and racing, where every gram on the rotating mass counts. It suits riders tackling rolling to moderately steep terrain who want climbing-friendly gearing without the weight penalty of a full steel setup. For extremely steep or sustained mountain climbs, some riders may still prefer the wider 11-36T steel option for extra low-end range.

Yes, this Ultra Lightweight Steel+Aluminium cassette is one of ZTTO's higher-tier offerings, and DoGoodCo sources it directly through verified channels to ensure you receive an authentic, correctly-machined component rather than an inferior copy. Given the premium engineering and weight-saving construction, the Rs. 23,600 price, GST-inclusive, reflects its position above ZTTO's standard steel cassette range.

This cassette is designed to shift smoothly with 12-speed drivetrains using a standard HG freehub, which covers most Shimano-based setups and SRAM mechanical groups on an HG driver. If you're running SRAM AXS with an XD/XDR driver body, this cassette isn't a direct fit, so do check your freehub type first. Let us know your groupset details and we can help confirm before you order.

Regular cleaning and lubrication are especially important here, since aluminium cogs are more prone to wear from grit and dry chain conditions than steel. Rinsing off mud and dust after monsoon or trail rides, and keeping the chain properly lubed, will help the aluminium cogs last as long as possible. Avoiding harsh cross-chaining habits also reduces unnecessary wear on the larger aluminium sprockets.
