A study in refined ruggedness—this is one bike to rule them all. Named for the road that brought pioneers over the Cascade Mountains on the final leg of the Oregon Trail, the Barlow is built for epic adventures. It draws on the aggressive geometry and precise handling of our award-winning Skyline road bike, while also maintaining the comfort and toughness of an off-road machine. Some might label this design “adventure rider,” “gravel racer,” or “endurance road,” but Sage Titanium’s versatile frame transcends those conventional categories. No, the Barlow relishes the rigors of the dirt while begging for the speed of the road. It loads up for a tour and can handle the long haul. It does not compromise, and it flashes with the class of titanium. It does it all.

A machined-titanium yoke enhances the drive-side chainstay and defines the Barlow’s versatility. The design clears 53/39 chain rings and a 40-millimeter tire while preserving normal crank arm spacing. It’s not constrained to smaller gearing, like a cyclocross bike. It’s not limited by narrow rubber, like a road bike. It’s suited for any adventure at any speed. Additionally, the combination of an oversized head tube and bi-ovalized down tube provides a stable platform for snappy acceleration and precise, confident handling, on or off the road.

The refinement trickles down to the finer details on the Barlow. It’s packed with stealth, technical minutia that make substantial impacts. Sage Titanium’s patented Cable Clip System (US Patent No. 9,545,975) streamlines mechanical cable or electronic wire routing for an attention to detail that reconciles aesthetics and functionality. Integrated fender/rack mounts and three water bottle cage mounts facilitate any extended wanderings away from civilization. Whether adventure takes you through a rotating pace line or over rugged mountain passes, the Barlow begs to ride it all in style.

  • 142 x 12mm Thru-Axle design
  • Flat Mount Disc Brake
  • CCS Ready (Electronic and Mechanical Drivetrain Capable)
  • Clearance for up to 40mm tires
  • Chainstay Yoke provides clearance for chainrings up to 53/39
  • Ovalized and shaped tubing for race ready performance
  • 44mm headtube provides razor sharp precision steering
  • Stealth fender and rack mounts for increased weather protection and touring capabilities

Cable Clip System (CCS)

Sage Titanium’s Cable Clip System streamlines shift routing with a touch of retro elegance. Officially recognized as US Patent No. 9,545,975, the design combines a single port under the down tube and a removable cable stop that work in harmony to sleekly route internal electronic wires or external mechanical cables. The machined-aluminum clip dovetails with the opening, guiding mechanical cables below the down tube. Ready to switch to an electronic drivetrain? There’s no upcharge for “Di2 compatibility” as the CCS seamlessly converts between mechanical and electronic systems. Removing the clip eliminates external cable stops and cleanly routes wires through the frame. The Oregon-made clasp also uses integrated barrel adjusters for fine-tunable functionality on this tiny chunk of genius.

Bi-Ovalized Down Tube

Snap. Precision. Giddy Up. All Sage bicycles are built upon these principles, and the bi-ovalized down tube is the foundation of these qualities. The oval shape provides a larger weld surface area compared to traditional round tubing. This increased contact patch better resists torsional forces at key locations on the frame. A vertical oval at the head tube junction resists twisting and yields precise steering, and a horizontal oval bonds to the bottom bracket shell, reinforcing lateral strength and preventing side-to-side movement during sharp accelerations. Mash, dive, sprint and swerve—the bi-ovalized down tube handles it all.

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.

Flat Mount Disc Brakes

Flat mount disc brakes add another level of refined elegance to the Barlow and Skyline Disc. The mounting bolts pull the caliper toward the frame, tucking it tight and secure onto the chainstay. The design eliminates tabs, removes excess bolts and results in more consistent braking with a streamlined, show-stopping look.

Sleeved Seat Tube

That clean weld on the seat tube isn’t just for looks–it’s the lynchpin of Sage’s sleeved seat tube construction. The design mimics the benefits of double-butted tubing, without succumbing to the drawback of increased stress risers. The thicker wall diameter above the weld creates a stronger junction with the seat stays and top tube, while a thinner wall diameter below shaves grams, maintaining the superior structural integrity of straight-gauge 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

Borrowed from the mountain bike realm, 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.

Barlow Chainstay Yoke

The perfect gravel bike is versatile, but it’s tough to do it all when traditional frame building techniques force a choice between bigger tires or bigger gears. Enter the Barlow’s chainstay yoke, a tweak on classic frame construction that reconciles the clearance conundrum. It’s a defining characteristic of the Barlow, and the foundation of this bike’s versatility. Located on the drive-side chainstay, the yoke allows for a 40-millimeter rear tire and 53/39 gearing all while maintaining normal Q factor and chainstay length. Don’t sacrifice. Don’t compromise. Have your wide rubber, and big gears too.

    One bike for a variety of terrains and surfaces was the best investment ever!

    My first ride on the Sage Titanium Barlow was a 100 mile road ride to the coast. I focused on feeling the bike out on climbs, sprints, and in the saddle paceline moments. The geometry is set up to provide a stable ride. Cornering was smooth and crisp while getting out of the saddle to build speed was easy. I forgot about the bike even on the hills as the bike performed perfectly.

    The next few long rides found some dirt and gravel. My group and I ventured out on recon trips around various logging roads. The low bottom bracket height provided stability while in the saddle, and even when mashing up fire roads to claim a KOM between friends. It’s no surprise that everyone wanted a turn on the bike when the next hill came.

    The addition of fenders when the season changes will be an added bonus as it will complete the rain and mud protection for me.

    I thought that adding another bike to the stable was going to put me in the doghouse, but that has not happened. Having one bike to ride on a variety of surfaces and terrains was the best investment ever for a single bike. Just change wheels and get after whatever adventure you want.

    I am flat out in awe of my Sage Titanium Barlow!

    I have been racing & riding for over 30 years, and have owned over that many bikes in that time. I am flat out in awe of my Sage Titanium Barlow after 6 months of riding it. I’ve now done wet, rainy base miles with fenders mounted, over 1,000 miles of gravel racing and epics, and even single track here and there. I am most impressed with the plush, stable ride downhill while simultaneously being able to carve corners with confidence. If I could keep only one bike in my stable it would be my Barlow as it can do just about anything.

    I finally found a worthy singular bike!

    Determined to eliminate the need for more than one bicycle to enjoy a variety of terrain, I spent years searching for the right bike, but it only took a week to become addicted to the Sage Titanium Barlow. The geometry lies between Road and Cross bikes so it’s stable at speed and corners well, but remains forgiving enough to shred trails. With clearance for fat tires, the Barlow floats nicely along gravel and has mounts for a 3rd water bottle cage, as well as separate mounts for a rack and fenders. This thing truly is an adventure bike. I’m glad my search is over and I finally found a worthy singular bike.

    The bike moves like no other bike I’ve ever owned.

    I have been LOVING my Sage Barlow. The bike moves like no other bike I’ve ever owned. It is so quiet to ride, as if it dampens vibrations, and yet it really leaps forward when I put the hammer down. The titanium looks beautiful, and it is such a pleasure to ride. I cannot say enough about how much I like this bike.
