TA, while probably the solution you'd arrive at if designing a bike for the first time right now, offers little if any true, quantifiable advantage in the rear or with a rigid fork. It offers much needed stabity and stiffness with a suspension fork.What's QR vs Thru Axle? Benefits or downsides?
Stories of rear hub flex (therefore thru-axle) are BS in my opinion. With a tightened QR and laced wheel there's no place for the hub flanges to go.
