Interbike Gear: Easton 2011 Stems

By: Squirrel | Wednesday, September 22, 2010

Easton has added some eye candy to their stem lineup for 2011, offering redesigned Haven and Havoc models as well as introducing a sexy new direct-mount option to the Havoc line.

An interesting feature being implemented across the product range is Easton’s Top Lock technology, which they claim makes over-tightened stems a thing of the past. Already utilized in Easton’s road stems, the Top Lock technology utilizes a non-symmetrical faceplate that is designed around a two-bolt tightening system. Top Lock stems are meant to be installed by bottoming out the top two bolts, creating a flush connection between the faceplate and the stem barrel, and then torquing the bottom two to spec.

According to Easton, in traditional designs where all four bolts are tightened down evenly, the stem faceplate will float under stress, making both the stem and bars more susceptible to failure. The greater strength allowed by the Top Lock interface allows Easton to spec smaller bolts, cutting down on weight.

Havoc Bolt-on: 135g, Fox 40, RockShox Boxxer and Manitou Dorado bolt-on compatibility, $90.

Havoc: 148g, 1 1/8 and 1 ½ steerer options, $90.

Haven: 145g, 55-, 70-, 85- and 100-millimeter options.
