Sidi's Tecno wire and dial system was one of the first of it's kind, and has widely been in use on motorcycle and cycling footwear for decades. Each generation has offered improved usage or features, and the Tecno 3 Push model has been very popular due to its' Push Button Release Tension system. As is nearly always the case with Sidi shoe features and all Tecno products, Sidi offers replacement parts for worn or damaged items.

The Sidi Tecno 3 Push Button Release Tensioner is available in several colorways, though the White and Black are most common. The system is also available in 2 wire lengths, Short or Long. Your shoe model and position of a needed replacement will determine whether or not you require a short or long version. Most Sidi's that have a dial and two anchor point at the top of the foot by the ankle require a short length to replace that piece. If your shoe has a lower dial with 4 anchor points, you need the long version. Some dedicated Sidi riders stock on on replacement parts for easy shoe maintenance long-term, but many mountain bikers and cross riders know to have a replacement Tecno dial available all the time in case of an impact or incident on the trail or course
