The integrated bar-stem combo and seatpost can help save weight, and also reduce road vibrations, adding comfort, but not mass.

Singletrack.com's Lennard Zinn talks about the fine details of a 4-bolt stem with titanium bolts.
I'm interested in buying the Deda Zero 100 stem you recently reviewed. However I noticed that the clamp size is listed as 31.7mm. The bar I wanted to use is the FSA K-Wing Carbon which has a clamp size listed as 31.8mm. Will the 0.1mm difference in size make this combination incompatible?
Steve Dear Steve,
Features: The Koski Stronghold Deluxe is a forged hollow stemof 6061-T6 aluminum with a four-bolt polished silver front plate. The shaftis matte black.The Stronghold Deluxe stem is available in two finishes, called “shotpeened black” and “polished silver,” two angles, namely 7 and 15 degrees,and five lengths: 60, 75, 95, 110 and 130mm.All of the bolts take a 5mm hex key.Likes: This is a handsome and lightweight stem available in lotsof finishes, angles and lengths. It is plenty stiff, and it has a largeclamping area with the bar (these two features are probably interrelated).Dislikes:
Features: The Mag00 is a superlight magnesium stem for an oversized31.7mm handlebar diameter. It is machined from AZ 80 A, T5 temper magnesium,under a controlled inert-gas atmosphere and immediately coated afterwardsto prevent the oxidation and consequent weakening of the magnesium.The four-bolt front cap is made of carbon fiber with, according to Deda,the fibers oriented along the lines of force. All bolts are 6/4 titaniumfor a 4mm hex key.The Mag 00 comes in an 80-degree angle with lengths of 90, 100, 110,120, 130 and 140mm.Likes: The stem is extremely light while being adequately stiff.I
Features: The matte-black Deda Newton is machined from 2024 T6aluminum. The silver front cap is held on with four titanium bolts, which,like the fork-steerer clamp, accept a 4mm hex key.The Newton comes in 90- and 95-degree angles in lengths of 105, 115and 125mm. The Deda N’Bar matches it in graphics and quality.Likes: Like the Newton road stem, this is a strong, superlightstem, and I find it to be adequately stiff.Dislikes: Not a one.Other: You have to very careful not to over-torque the smallbolts.The Deda single-bend bars, namely the N’Bar and BarOne, come only inthe relatively short 560mm
