SPECTRAL 125 CF

The Spectral 125 is a shredder’s short-travel whip. It’s a poppy, little machine that’s perfect for jibbing off every trail feature in sight. It also has the aggressive geo to tackle steep and sketchy trails.

140mm of front suspension, 125mm of rear suspension.

The Spectral 125 is a rowdy, short-travel trail bike with a true trail bike chassis that’s rated to the same Category 4 (enduro-level strength and impact resistance) standards as the Strive and our longer-travel Spectral models.

Compared to a trail bike with 150mm or more of rear suspension, the Spectral 125 boasts more responsiveness and pop—giving the rider a more direct feel, while still having the capability to take on some serious terrain should the mood and your skills take you there.

Of course, this bike is only packing 125mm of rear squish, so if tackling the world’s chunkiest gnar line is your constant and abiding passion, you’ll obviously have less margin for error with the Spectral 125 than with a long-travel model like the Spectral 29 or Torque. Different horses for courses and all that jazz…

While the Neuron and Spectral 125 have similar amounts of travel, the millimeters alone don’t tell an accurate story...these are very different bikes.The Neuron is more of an evenly balanced bike that appeals to riders seeking an exceptionally versatile bike that climbs and descends equally well. The Neuron boasts a very neutral seat position and geometry that delivers all day comfort—particularly on less extreme, more rolling terrain profiles

Spectral 125 is a short-travel bike for gravity riders. It has a more descending-oriented geometry and suspension tune than the Neuron, and a more responsive/capable chassis when ridden hard in technical terrain.

Both kinds of Spectrals can tackle a lot of the same trails—it’s just a matter of you want to feel while riding those trails.

The long-travel Spectrals let you plow through rough terrain thanks to their generous dose of deep, smooth suspension. You want maximum confidence when you are rocketing down rough trails or when you come up short on big jumps? Get a Spectral 29, Mullet, or 27.5 model.

Spectral 125, on the other hand, is perfectly suited to two types of riders:

The first group are aggressive riders who prefer an aggressive trail bike, but don’t necessarily want the Spectral’s full 160/150mm travel package. These riders simply prefer the snappy and playful feel of a slacked-out, short-travel bike. They charge hard but prefer to do so with less suspension travel.

The second group of riders are people who desire a rowdy kind of whip, but who don’t need a long-travel bike because they don’t live and ride somewhere littered with tons of massive hits. Plenty of people fall into this latter camp—riders whose home trails just don’t require 150mm or more of rear suspension.

If you fall into either of those two camps, get a Spectral 125.

If you are looking for the lightest possible weight and fastest climbing performance, choose the Lux Trail.

If you want an efficient, comfortable trail bike that evenly balances climbing and descending, go with the Neuron.

Finally, if you’re seeking a rowdy trail bike that excels on technical descents, yet climbs better than long-travel models, you should get the Spectral 125.

The Spectral CF frame weighs 2,500 grams.

The Spectral AL frame weighs 3,000 grams.

Frame weight is an obvious difference, with the carbon Spectral 125 frame weighs about 500 grams (1.1 pounds) less than its aluminum twin. There are also a few more bells and whistles built into the Spectral 125 CF frame.

The Spectral 125 CF uses a Flip Chip for geometry adjustment, features double-sealed bearings, replaceable pivot threads, and fully-guided, internal cable routing. The Spectral 125 AL features a single, fixed geometry and steel thread inserts. That said, we worked hard to make both aluminum and carbon frames feel as close to one another on the trail as possible. Both frame platforms are awesome.

29er only—front and rear.

The superior roll-over capabilities of 29 really comes in particularly handy on shorter-travel, full-suspension bikes. The full 29er set-up helps the shorter-travel Spectral 125 keep up with the bigger bikes in terms of speed, while the 125’s low weight and poppy nature keep the bike playful and fun.

Short answer: No. Longer answer: Still no¬—putting a smaller rear wheel on this frame will mess up the geometry and lead to more pedal strikes than any rider will find acceptable.

They’re nearly identical. We wanted to keep it as a version of the beloved Spectral, therefore the headtube and seat tube angles (among other dimensions) are the same. Headtube length and bottom bracket heights are slightly different since the Spectral 125 has less suspension travel and should be run with less sag than the longer-travel bike. Given the bike’s shorter-travel inclinations, we also gave the Spectral 125 a bit more reach (5mm), which opens up the cockpit a bit and benefits riders on climbs.

The carbon Spectral 125 models wear shocks measuring 210x50 (eye-to-eye/stroke) and which have 25x8mm(F) and 40x8mm(R) mounting hardware widths. The aluminum models sport shocks measuring 210x47.5mm (eye-to-eye/stroke) and which have 20x8mm(F) and 40x8m(R) mounting hardware widths.

We designed the Spectral 125 to ride best when set up with 25% rear suspension sag.

Since the carbon models feature shocks with 50mm of stroke, you should set up the bike with 12.5mm of sag on carbon Spectral 125s.

Aluminum Spectral 125’s, on the other hand, feature rear shocks with 47.5mm of stroke—so on the alloy Spectral 125, you should aim for 12mm of sag.

Nope. There generally isn’t enough clearance on the bike for coil shocks, so from a legalese “don’t break this bike by doing that thing” perspective, we are telling customers to not put on coil shocks. From a sheer performance standpoint, the Spectral 125 is also far better suited to air shock characteristics and we designed the bike’s kinematics with air-sprung suspension in mind.

Air-sprung, piggyback shocks fit fine within the Spectral 125 frame—even with a 600ML waterbottle mounted within the front triangle. We recommend our Sideloader cage and our FUEL600 waterbottle.

73MM British Threaded BB.

The Spectral 125 CF does not have ISCG tabs affixed to the bottom bracket shell, but we offer an optional ICSG plate (part # EP1266-01) aftermarket. The bike does feature an integrated top chain guide as standard. The Spectral 125 AL does not feature tabs or an ISCG plate.

34T is the biggest possible, 30T is the smallest possible. We recommend running 32t chainring.

Max tire width is 66mm, which amounts to 2.5” on most common tires
