You’d be surprised at how much similar bikes weigh be they alloy or carbon, though the wtb tyres are very weighty so yes that would drop weight. Any idea what yours does weigh?
I recently rode & tested a new Bird Aeris (nice bike) but it wasn’t as light as I would have expected it was nearly 32lbs even with a decent build kit on it. And my old Airdrop Edit v1 was 32lb too, both bikes were fun to ride and made your shoulders ache on hike a bike rides.
