When your riding reaches a level where you're cranking out double and even triple digit rides three to five times a week, you need all the support you can get. The Pinarello Tour bib short is designed to keep you cool and dry for hours, even in the heat of summer. It's also built to support your muscles while they work and reduce fatigue that's caused by constant vibration and impact.The Tour's main body fabric is 250g Power Lycra. This is a true compressive material that not only reduces the effects of road vibration, which can cause fatigue, but it also promotes bloodflow and protects muscles during long periods of high exertion. On the core contour system, Ametista fabric brings 200gm2 of gently supportive compression to your waist and core. It also incorporates carbon filaments, which reinforce the honeycomb knit Lycra, allowing for a lighter build that retains the strength of a heavier material. The carbon implants impart antimicrobial properties, and Pinarello claims that they also absorb atmospheric electrical interference for an increased anaerobic output and a delayed onset of fatigue. The shorts' body is kept in place by the usual bibs up top and the decidedly unusual 190 E leg bands down low. The 190 E bands spread a soft, non restrictive, and gently compressive grip across the 7. 5 centimeter wide cuffs. A silicone application is used throughout these bands to help keep everything in place. The LoPro 0 used in the front and shoulders of the bibs is the distant, less restrictive cousin to the LoPro 30 and 45 materials that Giordana uses in the cuffs and armbands of other items. The straps are hem less for a perfectly flat fit that doesn't show through your jersey. At the shoulder blades, the LoPro is mated to 190 Mesh, which is soft and breathable with a barely there feel that complements the band of ventilated Antigua material between the shorts' body and bibs.The chamois is the Cirro OmniForm O.
