size: 700x40, about 40.2mm wide
tread pattern: tightly packed small knobs for mostly dry conditions
construction: 120 tpi, flat protection
performance on pavement is excellent, like most touring tires this size with secure cornering on wet or dry pavement.
performance on firm gravel is excellent, with excellent cornering and braking
performance on deep or soft gravel is very good with good control and sufficient volume over rough surfaces. Excellent braking in soft conditions. Cornering performance and float on soft surfaces is limited by the lack of bigger knobs on the shoulder.
durability: good so far
ride: smooth and plush
