6061 Trail+ v2 Fat Bike - Raw / Black
Where the pavement ends, and then some.
A completely new frame, a much slacker front end, and hydraulic brakes. The 6061 Trail+ v2 trades its predecessor's conservative numbers for a 66° head angle, 455mm chainstays, and a 50mm stem on a 740mm bar — modern trail geometry applied to a fat bike.
Shimano 1x8 with an 11–45T cassette for a climbing gear low enough for deep snow. 180mm hydraulic discs front and rear. UDH dropouts, thru-axles both ends, internal dropper routing, and cargo mounts on the frame and fork. Kenda Juggernaut 26 x 4.5" tires, with room for 4.8".
current price, $1,199.99
A completely new frame, a much slacker front end, hydraulic brakes, and a dropper port. The fat bike grew up.
Version one was an honest entry-level fat bike. Version two is a different machine: new hydroformed 6061 frame drawn around modern progressive geometry, UDH dropouts, thru-axles front and rear, 180mm hydraulic discs, internal dropper routing, and a wide-range Shimano drivetrain with a genuinely low climbing gear.
Sand, snow, desert singletrack, and the kind of terrain where a 4.5" tire is the only thing that makes sense.
What changed from V1
Almost everything that touches how the bike rides.
- All-new hydroformed 6061 frame
- 66° head angle — much slacker
- UDH thru-axle dropouts
- Internal dropper routing
- Cargo and bottle mounts
- Hydraulic discs replace mechanical
- 180mm rotors front and rear
- Thru-axles: 150x15mm / 197x12mm
- Upgraded sealed-bearing hubs
- 11–45T wide-range cassette
- Shimano ESSA, Rapidfire Plus shifter
- 740mm bar, up from 700mm
- 50mm stem, down from 70mm
The geometry is the headline
V1 handled like what it was — a budget fat bike built on conservative numbers. V2 was drawn from scratch, and the front end is where you feel it.
- 66° head tube angle. Slack. Most fat bikes in this class sit at 69°. Three degrees sounds small on paper and is enormous in practice: the front wheel leads the bike instead of darting, and it stops trying to tuck under you on a steep, loose descent.
- 455mm chainstays across every size. Long rear center keeps weight between the wheels, which is exactly what you want when the rear tire is searching for traction in sand or snow.
- 65mm bottom bracket drop. Low. Your weight sits below the axles — the thing that makes a bike feel planted in corners and on off-camber terrain.
- 45mm fork offset paired with that slack head angle puts a lot of trail under the front wheel. That's what makes the bike track straight through soft sand and chewed-up snow instead of wandering.
- 50mm stem on a 740mm bar. The short stem and wide bar are part of the geometry, not an afterthought. Steering gets precise and the weight distribution stays where the frame wants it.
Long front center, long rear center, slack head angle, short stem. It's the layout every good modern trail bike uses, applied to a fat bike.
Hydraulic brakes, finally
V1 ran mechanical Tektro calipers. V2 runs Tektro HD-M275 hydraulic discs with 180mm rotors front and rear, on post mounts.
This matters more on a fat bike than on anything else. You're moving a lot of rotating mass — a 4.5" tire and rim assembly is heavy, and it carries real momentum. Mechanical brakes on a fat bike mean squeezing hard and hoping. Sealed hydraulics with big rotors mean one or two fingers and actual control over how fast you slow down, which is the difference between modulating a descent and surviving it.
180mm front and rear is deliberate. Plenty of bikes step down to a smaller rear rotor to save weight. On something this heavy, carrying gear, on loose ground, the rear brake does real work.
Eight speeds, 409% of range
A Shimano ESSA 1x8 drivetrain: 11–45T cassette, RD-U2000 Shadow rear derailleur, and an SL-M315 Rapidfire Plus shifter with an optical gear display.
V1 was 9-speed with an 11–36T cassette. V2 has one fewer cog and a much wider spread:
- V1: 11–36T — 327% range
- V2: 11–45T — 409% range
That bottom gear is the point. Fat bikes get ridden up things — soft sand, deep snow, loaded climbs — where cadence collapses and you need somewhere lower to go. Trading a cog for nine more teeth at the back is the right trade every time on this kind of bike.
Eight speed also means a cheaper chain, a cheaper cassette, and a drivetrain that tolerates being a little out of tune. On a bike that spends its life in sand, salt, and snowmelt, that's not a compromise — it's the correct spec.
Cassette steps: 11-13-15-18-22-27-35-45T, paired with a 28T chainring on 170mm cranks.
Choose Your Seatpost
A dropper is the single biggest upgrade you can make to a bike like this. V1 had no provision for one at all — V2 has the port and the internal routing already in the frame, on a 31.6mm seat tube.
On a fat bike it earns its place faster than you'd think: dune drops, technical descents, off-camber snow where you want your weight back and the saddle out of the way. Two ways to get one.
- 31.6 x 350mm alloy, State Bicycle Co. laser-etched
- Frame is dropper-ready whenever you are — internal routing already in place

Seekrun S7 Wireless Dropper Bundle
- Fully wireless actuation with a bar-mounted remote
- No cable to route, no housing to trim, no drag to fight
- Roughly 9,000 drops per charge, IP67 sealed — rated for the wet, cold, and gritty
- Bundle includes post, remote, battery, and charger
How much post will fit. Maximum insertion depth into the seat tube, by size:
- Small (42cm): ~206mm
- Medium (46cm): ~246mm
- Large (50cm): ~286mm
Check your dropper's minimum insertion requirement against the figure for your size before ordering. Longer-travel posts need more depth, and on the Small in particular a shorter-travel post may be the only thing that fits with the saddle at your pedaling height.
Room for 4.8" rubber
Every build ships on Kenda Juggernaut 26 x 4.5" tires, and the frame has room past that:
- Up to 26 x 4.8"
- Ships with 4.5" Juggernaut
- Up to 26 x 4.6"
- Thru-axle, cargo mounts
- Up to 26 x 4.8"
- Matches the frame's rear clearance
If you plan to run the widest rubber the frame will take, the carbon fork is the only way to do it front and rear.
Carbon fork upgrade — $299.99
Every build ships with the matched alloy rigid fork: thru-axle dropouts, cargo mounts, 485mm axle-to-crown.
The carbon fork is a $299.99 upgrade, and it does two things. Weight comes off the very front of the bike, which is the place you feel it most — in how the bike lifts over obstacles and in the first thirty feet of every ride. Carbon also damps high-frequency chatter, which on a rigid bike running low pressure is a real comfort gain on frozen ruts and washboard.
And it opens up the extra tire clearance: 4.8" versus 4.6" on the alloy fork.
- Axle-to-crown: 491mm
- Offset: 40.2mm
- Steerer: Tapered, 1-1/8" to 1.5"
- Axle: 150mm x 15mm thru-axle
- Mounts: Same cargo mount provisions as the alloy fork
The carbon fork is 6mm longer and 4.8mm less offset than the alloy fork, which slackens the front end very slightly and adds a little trail. In practice it makes an already-stable bike marginally more stable.
UDH and modern axle standards
Universal Derailleur Hanger dropouts. A replacement is available at virtually any shop anywhere in the world — no proprietary part to source after you drop the bike on its drive side a thousand miles from home. It also opens a path to modern direct-mount drivetrains later without needing a different frame.
Thru-axles front and rear. V1 used a 135mm quick-release front and a 190mm quick-release rear. V2 moves to 150mm x 15mm front and 197mm x 12mm rear thru-axles on upgraded sealed-bearing hubs. Stiffer, more precise, and the wheel goes back in the same place every time.
Mounts for actual bikepacking
New on V2: cargo mounts on the top tube and the down tube, plus bottle mounts. The fork gained cargo mounts too — on both the alloy and the carbon version.
Fat bikes and bikepacking belong together — the whole premise is going where roads aren't, and that usually means carrying what you need. V1 gave you a frame and a hope. V2 gives you threaded bosses where you want to bolt things: a top tube bag, cargo cages on the fork, a bottle inside the frame instead of strapped to the bars.
Tire pressure — read this part
Tire pressure is the single most important adjustment on a fat bike, and it's the one most new owners get wrong. These tires run far softer than anything else you've owned — a floor pump gauge often won't even read accurately that low. A low-pressure gauge is worth the ten dollars.
The Kenda Juggernaut is rated 5 to 30 PSI. Where you sit in that range changes the bike completely:
- Deep snow or soft sand: 5–8 psi. Low enough that the tire visibly flattens and floats instead of digging in.
- Packed snow, dirt, hardpack trail: 8–12 psi.
- Pavement and gravel road miles: 12–15 psi. Rolls faster, still comfortable.
Start in the middle and let air out until it feels right. Most people's first instinct is to run far too much pressure, which gives up the entire reason to ride a fat bike. You will almost never want to be near 30.
Ships with tubes installed. These rims and tires are not rated for tubeless setup.
Geometry
Shared across all three sizes:
- Head tube angle: 66°
- Seat tube angle: 74°
- Chainstay / rear center: 455mm
- Bottom bracket drop: 65mm
- Fork offset: 45mm (alloy fork)
- Fork axle-to-crown: 485mm (alloy fork)
By size:
- Small (42cm) — reach 450.5mm · stack 591.1mm · top tube 620mm · seat tube 420mm · head tube 110mm · front center 736.9mm · wheelbase 1184.3mm
- Medium (46cm) — reach 467.9mm · stack 600.2mm · top tube 640mm · seat tube 460mm · head tube 120mm · front center 758.2mm · wheelbase 1205.8mm
- Large (50cm) — reach 480.3mm · stack 609.4mm · top tube 655mm · seat tube 500mm · head tube 130mm · front center 774.6mm · wheelbase 1222.2mm
Handling is consistent across the range — every size shares the same head angle, chainstay length, bottom bracket drop, and fork offset. Only the front end grows.
Size Recommendations
- Small (42cm): riders 5'6" – 5'10"
- Medium (46cm): riders 5'9" – 6'1"
- Large (50cm): riders 6'0" – 6'5"
Sizes overlap on purpose. If you fall between two, the smaller size gives a more nimble, upright fit and the larger one stretches you out. With a 50mm stem and a 740mm bar, reach is the number worth comparing against a bike you already ride. Full numbers are on our geometry chart.

Anyone whose riding season currently stops when the conditions get stupid. Snow, sand, mud, washed-out desert doubletrack, beach at low tide. A 4.5" tire at 7 psi floats over surfaces that would stop a 2.4" trail tire cold — and with V2's geometry, hydraulic brakes, and a dropper port, you can actually ride it fast rather than just survive it.

FAQ
Rider-owned in Phoenix, AZ since 2009. 5-year frame warranty on steel, aluminum & titanium · most in-stock bikes ship in 1 business day · 4.8/5 from 16,000+ reviews.
How does my bike show up, and do I need a shop?
That depends on how you order it:
- With Pro-Build (select models: $79.99, or $129.99 on Carbon Road). Our mechanics in Phoenix face the frame, set up and bleed the hydraulic brakes, index the drivetrain, cut the steerer to our stock length and torque-check everything before it goes in the box. That's the shop work that usually runs $150–$300 locally. You bolt on the bars, seatpost, front wheel and pedals, set your hoods and wrap your tape: about 20–30 minutes with a hex set and a torque wrench. Pro-Build adds a 1–2 week build queue.
- Without Pro-Build. Your bike ships mostly assembled, but it needs a full assembly and tune by a professional mechanic before it's ride-ready. Carbon, titanium and AXS builds that skip Pro-Build arrive unassembled with an uncut steerer, so your shop can build them to your exact fit.
Either way, a professional build is safer, rides better, and unlocks our better warranty tier (see below).
What does the warranty cover?
Every State bike comes with our Standard Limited Warranty against manufacturing defects for the original owner. No registration required.
- Steel, aluminum & titanium frames and forks: 5 years
- Carbon frames and forks: 1 year (2 years with ProBuild Advantage)
- Non-consumable parts (cranks, wheels, hubs, bars, stem, seatpost, pedals): 1 year
Not covered: wear items (tires, tubes, chains, brake pads, grips, bar tape, saddles, spokes, paint), rust on RAW finishes, crash damage, and labor or shipping costs. Full warranty details
What is ProBuild Advantage, and how do I get it?
It's our "you did it right" warranty tier for bikes that were professionally assembled and registered within 30 days of delivery. You get everything in the Standard warranty, plus:
- 2 years on carbon frames and forks, instead of 1
- Priority claim review: ProBuild claims go to the front of the line
- Faster help with shifting or braking issues, without the "did you tighten that bolt?" back-and-forth
- Shipping perks on approved warranty replacement parts
- Discounted pricing on a replacement frame or bike for up to 5 years from delivery, if a crash wins
To activate it: add Pro-Build when you order, or have a local shop assemble your bike and keep the receipt. Then register your bike within 30 days of delivery with your serial number (engraved under the bottom bracket shell) and proof of assembly. If you ordered Pro-Build, our mechanics already did the build. You just register.
When will my bike ship?
Most in-stock bikes ship within 1 business day, and you'll get tracking as soon as yours is on its way. Adding Pro-Build puts your bike in our build queue for 1–2 weeks before it ships. Shipping is calculated at checkout from your location and the size of your order, and bikes go out by UPS or FedEx Ground.
Outside the U.S.? We ship worldwide, and duties and taxes are paid at checkout, so nothing is due on delivery. Shipping policy
What if it's not right? Returns & exchanges
You have 30 days from delivery to request a return or exchange. Bikes need to be unused, in like-new condition and in their original packaging.
- Refunds: a return label fee is deducted ($45 for complete bikes), and original shipping isn't refundable.
- Exchanges: issued as store credit. The return label fee applies here too.
- Package Protection Plan (add it at checkout): covers loss and damage in transit, removes return label fees and deductions, and extends the window for exchanges and store credit to 60 days. Refunds stay at 30 days.
Pro-Build and other service work can't be refunded once it's done. Final sale, clearance and limited-run items can't be returned, and neither can international orders.
Can I pay over time, or use HSA/FSA funds?
Yes. Financing with Bread Pay splits your bike into monthly payments, and you can pay it off early with no penalty (subject to credit approval). You may also be able to use pre-tax HSA/FSA dollars through Truemed. A short intake at checkout checks your eligibility, which depends on your plan. HSA/FSA guide
Which size do I need?
Geometry charts, size guides and full build specs for every model are on our Size Charts & Specs page. Between sizes, or running a tall stack or long stem? Get in touch before you order. Pro-Build cuts the steerer to our stock length, and that can't be undone.
Can I see one in person or get it built locally?
Use our dealer & shop locator to find a shop near you for a look in person, assembly or a tune-up.
Something arrived damaged or missing?
Email info@statebicycle.com within 30 days of delivery with your order number and photos of the item, the box damage and the shipping label, and our team will take care of you. If a part has failed, submit a warranty claim. You can also reach us at 1-855-55-STATE or through our contact page.
