XC RACE BIKE: tHE REFINED RIPPER

The gun fires. The race has begun. It’s an all-out sprint to make it to the first chokepoint on the course before the inevitable bottleneck will occur. Elbows out, head down, eyes focused straight ahead, your desire is to get to the singletrack without any delay. You split riders as you sprint past them for that small place visible up the trail, and once you have gained your position the real race begins.

The Optimator was designed to be a World Cup level XC race bike. Using inspiration from the current XCO World Cup Courses that the top professionals ride, Optimator has one purpose and that is to get you to the line first. A 69.5° head angle combined with an 83mm Trail figure will keep you on your toes as you are able to navigate the most technical sections of the course due to the agile steering. The short chainstays provide plenty of snappy acceleration when you need to bridge a gap or distance the rider behind you. When the course gets super technical, use the internally routed dropper post to get your saddle out of the way so you can attack the features in front of you.

Racing is all about making choices in the heat of the battle so that the outcome will be in your favor. Jumping a rooted/ rocky section to save a few extra seconds or picking the right lines as the course evolves over the duration of a race will help ensure a very good race at the very least. Racing on a bike designed to get you to the finish line first is the final piece of the puzzle in your quest for the race win. The Sage Titanium Optimator is your XC weapon of choice.

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.
