The mtb tire with the greatest range of applications. Touring and all mountain riders love them. Seen in fast cross-country racing, as well as in technically demanding enduro competition. Nobby nic enters the third generation. The new snakeskin sidewall is standard and makes it immune to cuts and blows, while tubeless conversion is as easy and safe as never before. Nobby nic is a mountain biker s best friend. Note: when converting light weight mtb racing tires to tubeless, the process can take up to 3 days of consistent sealing and sealant will seep from the sidewalls of the tires. Liteskin mtb racing tires are inherently thin in the sidewalls and will require extra care. Do not exceed 35 psi on tubeless applications.
