Shred the preconceptions of an all-mountain trail bike. That philosophy inspired the Sage Flow Motion–a hardcore hardtail born on the legendary trails of Sandy Ridge, Oregon, and handmade right here in Portland. Don’t let the lusty titanium frame fool you– we built this burly beauty to test the limits. Launch it. Rip it. Climb it. Whip it. Drop it. Flow. This is the refined ripper.

Progressive, playful geometry is the foundation of this versatile frame. Want to soak up jumps and thread the gnarliest the descents? Choose a 160-millimeter fork for a slacker head angle and a nimble bottom bracket height. The Boost chainstays add further versatility, accommodating 27.5 x 2.6″ or 29 x 2.2-inch tires.

Unburdened by the complexity of pivots, the Flow Motion is light and snappy. Climb to the summit with the efficiency that only a hardtail can boast. Rail berms with the short chainstays and a playful bottom bracket height. Launch doubles with stability thanks to the extended reach and internal dropper post routing. Send it with the confidence, knowing that you’ll landing on the strongest 3/2.5 titanium tubing. Session those sections until you can session no more. Shred the limits. Find your Flow.

3/2.5 Titanium

At Sage, 3/2.5 titanium is the magic material. The smooth riding alloy blends stiffness, durability and weight for the ultimate frame tubing. Titanium has a superior strength-to-weight ratio compared with steel and aluminum, and the fatigue tolerance far surpasses the other materials. Don’t fret long rain rides or brackish water crossings—3/2.5 titanium resists rust and corrosion better than any other metal tubing.

Industrial Finish

All Sage frames have a raw finish with the titanium shinning in all its glory. But industrial brushing is not just simple with a sexy shimmer. It’s also practical. The lusty sheen can be polished and renewed time after time. While bead-blasted and high-polished titanium frames have an alternatively classy look, any cosmetic flaws must be fixed by the pros at the paint shop or titanium factory. Should the industrial finish scratch or scuff, simply grab a Scotch-Brite pad to buff out the blemishes. A little elbow grease and DIY initiative brings the bike back to life, giving the frame that polished glow like the day it first rolled onto the doorstep. Or send your frame to us, and Sage will refresh it with a full buff and new set of decals.

English Threaded Bottom Bracket

Classic and classy, the English-threaded bottom bracket reigns supreme over press-fit alternatives. The strong interface between bottom bracket cups and the frame eliminates creaks and maintains alignment that won’t slip or wobble over time. Additionally, installation, removal and service of the design are simply superior. No punching or pressing required. Just thread it, grease it, shred it. Repeat.

Oversized 44-Millimeter Head Tube

The oversized 44-millimeter head tube affords phenomenal front-end stiffness and precision on the road. Press-in headset cups provide a secure interface between frame and cockpit, and the large diameter opening accepts a wide range of steerer tubes, from 1⅛-inch straight to 1⅛–1½-inch tapered and every combination between.
