Calculated VSR R Series Fat Mouth Stem 40mm Reach (Black)

The legendary Calculated VSR Fat Mouth Stem is a top load stem with a difference. Offering greater clamping power and stiffness for a standard sized 22.2mm handlebar. 

The "fat mouth" of the Fat Mouth stem is the obvious differentiator. In VSR’s own words “Wider bar clamping so you get more stiffness out of your standard diameter handlebars than you would get with those silly looking 31.8 bars that cost too much, and are limited in rise/sweep options.”

Despite it's bulky appearance the 40mm reach Fat Mouth stem weighs in at a reasonable 345grams.
