Mountain Biking Pure and Simple

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

Belt Drive

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.

Kobe Slider 3 Dropouts

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.

Force-response frame

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.

Modern Geometry

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.

Plus or 29

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.

Groovy Guides

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.

Lifetime warranty

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.

Awesome bike!

I only have one wet and sloppy PNW winter ride on it so far, but I was very impressed. The ride is a lot less harsh than my older aluminum single speed, and the belt drive is great in the rain and mud - no noise or grinding and a lot quicker to clean up afterwards compared to a chain. The most surprising part was when I pointed the bike downhill - I was as fast or faster than on my older 100mm full suspension xc bike on a dry day without really pushing. The 120mm Fox 34 probably deserves a lot of the credit for that, but the rear end was also pretty planted and easy to control, more so that I expected for a hardtail on rough and rocky trails.

The frame quality is amazing, and I particularly like the medium size that I got (which isn't pictured). The top tube and seatstays are in a perfectly straight line from the handlebars to the rear axle, which always looks cool. I also love that Spot included the derailleur hanger dropout as an extra with the single speed bike - I plan on running this bike geared some times, and was super happy that I didn't have to order additional parts to do so!

My only complaint is that the 5 star build's crankset isn't on the same level as every other part on the bike. A lighter, higher end crankset would make the 5-star build perfect!

Simple and Fun Bike

6 rides in and loving this bike. Well built frame, good components, and the simple joy of riding a bike without having to think about shifting. Light, snappy, excellent climber, and with modern geometry and dropper descents are fun and in control. Minor thing...would like to see it come with wider rims/tires but that's most due to the rocky and loose terrain around where I ride...easy fix on my part. All in all quite possibly the perfect single speed IMHO. Nice work Spot!

Awesome bike.

Five stars all the way around. Super light. Super responsive. No unnecessary non-sense like derailleurs and gears the complicate and weigh it down. Possibly the perfect bike. Local bike shop workers asking lots questions about where I got this bike...

So far so good...

To give you some background, my local trails are tight twisty singletrack with short ups and downs, no big climbs. Was riding a geared Spec Fuse AL 27.5+ and got the itch for a singlespeed...wound up buying the 5star Rocker 27.5+.

The preorder customer service from Spot was great...quick and helpful. The fit and finish on the Rocker is pretty awesome. I have taken it out a few times now and gotten it dialed in. It climbs great, I can work it through the tight twisty stuff, the components are all smooth, it's nice and light, and the frame/bars/wheels seem to soak up a lot of the trail chatter. It's not a night & day difference from the Fuse, but it feels better in all the right ways! I'm not sure if it's the belt drive, or just a single speed drive in general, but it feels a lot more direct compared to running my geared in a single gear.

I had Spot swap out the rear cog for a 26t (kept the 46t ring up front, and 118t belt). The belt is a fixed length so the rear wheel needs to come back further to pick up the slack from the smaller cog. You can't just remove a chain link. It made me realize that the gearing with the belt drive is tricky. You only have so much adjustment in the chainstay length to tighten the belt, so it may require a new belt and/or new cog+ring to get the gear ratio right......so make sure you know what ratio you want before ordering so you could have Spot set it up with the correct components out of the box. And it also looks like the 46t ring…

Better than expected.

The bike is everything I expected and more.

The belt drive system is very quiet , the gearing is perfect.

I ride lots of single track with rolling hills and rocky terrane with the proper planning I can climb most of the hills that that I did on my Specialized Epic Pro with a 1 x12

Very Lite and Fun to Ride

I chose the middle level build.
