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.
I'm setting my Rocker SS up for gravel racing by switching the rear cog to a 19T and changed the tires to Vittoria Terreno. Getting a good feel for the bike with 250 miles ridden at this time. It is as fast and smooth as I hoped it would be with quick steering. First race in two weeks with a weather forecast of rain mixed with snow.
Ordered 4-star build and sat on a waiting list for a month or so. First shipment had a cracked top tube that somehow happened during shipping. Mitchell @ Spot had a new frame sent out to me almost immediately with no questions asked.
The bike is absolutely perfect. My local trails are a good mix of short, smooth downhill sections and super punchy and technical climbs. It's hard to believe this thing is a hardtail at all. Tires will need to be swapped come summer, but I genuinely can't think of anything else I'd change. And for those worried about the carbon aspect: It's only been a few months, but I've put the bike through the wringer and it can definitely take a beating. I was skeptical about some drops at first. After working up the courage and building to them slowly, any worries or concerns about big drops I previously held are gone. Now don't go taking any 5ft drops to flat, obviously, but anything with a decently smooth landing should be fine.
I'm so impressed with the bike and company that I decided to impulse-buy an ACME the other day for commuting around town and I can't wait.
It is beautiful to look at, and impressive to pick up given its weight! It is very responsive and super fun to ride. I have not yet ridden in hilly terrain but it was perfect for Santos Trails in North Florida (too much snow at home to try out). It is very capable on technical terrain. The dropper post is the best I have ever used and will be my go-to in the future. I do not feel fully confident with the brakes, as the only constructive comment, but will try them out further before making up my mind. Great service and no regrets with my purchase
Comfort, speed, handling, and it’s a great looker too!
I got the 5 Star build SS. Very compliant rear end and super stiff BB makes for great descending and climbing. Wish it had a bash guard to protect the belt. This really should come standard with the bike. I asked about aftermarket bash guards but Spot didn't have any suggestions. Also, my bike came with TruVative cranks instead of the Sram ones that were part of the 5 Star build. Was looking forward to the red belt for the bling, but it came with a black one. Overall, very happy with the bike.
