Specialized E5 Premium Aluminum Disc Frame With D'Aluisio Smartweld Technology

Wheel Size – 700c

Large Tire Clearance – More clearance means more capability. That’s why the Crux DSW has the same tire clearance as its carbon sibling: 47mm and up to 2.1” on a 650b wheel. Combine this with the tough and light alloy frame, and Crux DSW can take you anywhere you imagine at full gas.

Ultra-Responsive – Responsive at the pedals. Supple in the saddle. We’ve used D’Aluisio Smartweld to fine-tune the properties of alloy to deliver a ride previously impossible without carbon and combine it with the same performance gravel geometry and race-influenced fit as the carbon Crux. A longer reach delivers better weight distribution for quick, confident handling, while a lower stack creates a performance first position. At 72mm of bottom-bracket drop, Specialized hit the sweet spot between nimble and stable.

D’Aluisio Smartweld – D’Aluisio Smartweld - or DSW - is a patented engineering process that uses hydroforming to precisely match tube-to-tube joints for better, stronger welds and, ultimately, a lighter frame that can be twice as durable as a traditional alloy frame. The Smartweld technique helps create a unique single-piece downtube and bottom bracket for the Crux, shaving weight and amplifying responsiveness.
