Richard D.wrote a review of Vittoria Barzo TNT Tire - 27.5in on August 13, 2016
Familiarity: I've used it several times
Like the tires. Nice grip with good damping through rocky bits - and fast on downhill sections. Only downside is they were 40g heavier per tire than the published spec. Vittoria lists this tire at 580g on their site and package however they both weighed in at 620g. Not a small margin... good for training but too heavy for a race tire. If not for this they would get 5 stars.
