The company we now know as DT Swiss has been drawing steel in Biel for over 350 years and their spokes are still made completely in house in Switzerland to the highest possible standards of quality and workmanshipThe DT Aero Comp is a very tough double butted bladed spoke that is perfect for all round use, from road and track to XC or Trail mountain bikesThe 14 / 15 / 14 gauge double butted spoke has a central bladed section giving aerodynamic advantage, but 2 mm thick at the end where strength is neededWhereas other brands stretch and weaken their spokes to butt them, DT's unique and closely patented ultrasonic peening process cold forges the spoke, actually strengthening the metal, giving DT's the best strength to weight ratio of any butted spokesMade exclusively from Swedish X5 stainless steel that is custom blended just for DTThe rolling of the nipple thread removes no metal from the spoke and preserves the grain of the material, maximising strength and greatly reducing the likelihood of failure at the threads, a common issue with lower quality spokesFinished in black using an electro-chemical treatment that is durable, and does not weaken the spokeWeight: 380 grams for 64 x 264 mm length spokes, 2 mm thread
