Terrene's McFly plus tire is available for both 27.5+ and 29+ wheels and in two different casing weights. It's burly enough for technical descending, yet fast-rolling enough for long days in the saddle.
Recommendation: Great tire for all around riding. While not specific for any type or style of riding, adequate in a variety of conditions and settings. Actually not as heavy as Terrene publishes on their site. I recommend the TekShield casing unless on very mild, smooth terrain.
