Singlespeed mountain biking is trail riding distilled to its purest elements: you, the trail, one gear, no excuses. Our new Rocker SS embodies that pure simplicity and elevates it with a lightweight yet burly full-carbon frame, a red-hot belt drive and other innovations that make this the fastest and most technologically advanced singlespeed MTB on the market.
Weighing in as low as 2.8 pounds, the Rocker’s frame, upgraded from our previous steel version, is nimble, strong, and versatile, with derailleur-ready dropouts should you decide to gear up down the road. The Gates Carbon Drive belt never stretches, never rusts, withstands chain-snapping torque loads and is a proven race winner.
We spec a dropper post on the wide-diameter seat post for aggressive descending, and the Rocker has ample clearance for wide tires that enhance ride feel and control. Our patented Kobe 3 Slider Dropouts make rear flat fixes a cinch—just pop the wheel back in without having to adjust the belt tension or fiddle around.
Spot was a pioneer in the resurgence of singlespeed mountain biking with our steel Rockers. Now we have raised the bar again by creating the ultimate no-nonsense grab-and-go bike for after-work fitness rides or weekend races. Rediscover your passion for fast and light trail riding in its simplest form. It’s just you and the mountain, now go.
#rockerlife
We designed the Gates Carbon Drive CenterTrack system. For singlespeeders who want to go fast, it is a proven race winner. With its incredibly strong carbon tensile cords embedded within a no-rust and grease-free polyurethane body, the Gates Carbon Drive system, developed right here in Colorado, is highest performing, lowest maintenance, longest lasting and lightest SS drivetrain available.
Our patented Kobe Slider Dropouts are the lightest, most compact, and easiest to adjust chain- or belt-drive-optimized sliding dropouts on the market. They offer 15mm of slider throw, an inboard brake mount for better protection, and precise adjustments capabilities for optimal tension. Tire fixes are easy. Drop the rear wheel as you would with any thru-axle dropout, then pop it back into position with no adjustments, and resume riding. Singlespeed belt or geared chain.
We designed the Rocker frame based on detailed analysis and testing both in the lab and on the trail. The frame shape is driven by a Force-Response design philosophy that maximizes strength and durability, and focuses material in areas where it is most needed. Beefy chainstays (or belt stays) handle huge power loads and prevent flex, keeping the belt straight and true. Svelte seatstays provide comfort in the saddle. The large box section downtube streamlines power transfer between the handlebars and pedals, while the trim top tube saves weight, lowers the center of mass, and provides easy stand-over clearance.
The Rocker is a modern hardtail that is light enough to race yet burly enough to air out and descend with trail bikes due to its dropper post, long reach, steep seattube angle and relaxed headtube angle. It’s a confidence inspiring bike on challenging downhills.
We offer the Rocker as a 29er with clearance for up to 2.4 tires, or as a 27.5-plus with clearance for tires up to 2.8. Because we believe in options. The 29 is faster, lighter and offers lower rolling resistance and tighter steering response. The Plus offers more grip, more comfort and better balance on rough trails at low speeds.
Hose lines on a beautifully shaped bike frame are kind of like those overhead power lines that ruin your view of the sky: they are butt ugly and could easily be hidden with some effort. Our Groovy Guides integrate the rear brake line into the tube, providing a clean look while also offering easier access than internal cable routing. Our Groovy Guides make it easy to service what may be the most important cable on your bike, while also keeping it out of the way and eliminating snags. One more example of how we sweat the small details to enhance your ride performance.
We design and test our frames to the highest standards so you can be confident in your investment. Should you have an issue with your Spot frame, we will warranty it against manufacturing defects for the lifetime of the frame. Of course there's some fine print (read here), but if you buy a bike and ride it as it is intended to be ridden, we've got your back. And if you do get into a fender-bender, we have a fantastic crash replacement program as well.
This Roker SS is pretty amazing the way it performs. So much fun and simple. After a handful of rides it is becoming more and more my go to bike over my full suspension.
Simple, solid, sturdy, and stylish.
Great single speed, belt needs a little silicone spray if running dust dry trails but same as a chain
I absolutely love this bike. It’s my favorite in my stable.
I’ve been riding my original steel SSRocker for over a decade, it became my favorite ride among many. I recently bought the new Carbon belt drive, I’ve had it for about 1 month and it’s the only bike I’ve ridden this spring! I usually wait till I have some miles on my legs to jump on the single speed, but this bike is so fast, light and fun I find it’s what I want to ride! I smile a lot while riding it. What more can I say?
