Purchased this stem and matching EC 90 SLX bar for a new build on a Specialized S-works Aethos frame. Emphasis was on light weight. The graphics are understated but classy and match the bar. The weight listed in the description is 138 g which is incorrect. My 90 mm stem weighs 114 grams which is super light for an alloy stem (or even a carbon stem). This SL stem is priced $60 more than the non SL version, but the surprise is that the SL stem includes the Easton faceplate Garmin mount which normally sells for $20 separately and is a nice integrated mount (Garmin only). This added bonus plus lighter weight offers great value over comparable lightweight stems.
Don't have a ton of miles on this things, but so far, so amazing. My other bike is a more traditional, classic steel frame with 1-inch steerer and quill stem. And about the lightest you can go with a quill stem is 250g (that's after cutting the column down a little too). So to get stem that is ~100g is pretty nice. I like the anodized black, and Easton does a tasteful logo IMO, as logo design goes.
