Vittoria Competition Latex Tube Say goodbye to rolling resistance Tubes are often an overlooked part of one's bike setup. The friction caused by your standard run of the mill tubes causes increased rolling resistance, meaning that you have to work harder to keep your speed up. In a race scenario, rolling resistance is key, Vittoria's Competition Latex Tube is designed specifically to eke out as much performance from your setup as possible and to deliver you to the top podium spot. They're incredibly lightweight, allowing you to accelerate faster and hold your speed for longer. The focus on reducing friction has allowed Vittoria to cut out as much rolling resistance as possible for true race optimized performance. Pair these with a Vittoria race tire or another high TPI road race tire for the absolute fastest and best performing setup. Features Lightweight construction for improved accelerations Low friction design reduces rolling resistance as much as possible Race specific tubes aren't ideal for day in and day out riding Perfectly paired with high end race tires for unbeatable speed, comfort, and cornering SPECIFICATIONSWheel Size700c Width19c-23c, 25c-28c, 30c-38c Valve Type Presta Removable Core Stem Length / Type48mm Weight19c-23c (75g), 25c-28c (85g), 30c-38c (105g) | Vittoria | Competition Latex Tube Presta 48Mm Valve, 25/28
