Fit
Find your size
Sizes overlap on purpose. Between two, the smaller rides more upright and the larger stretches you out. Every size shares a 435mm chain stay and a 50mm fork offset, so the handling stays the same across the range. The L and XL are preorders, shipping mid October.

Carbon All-Road Overview
The State Bicycle Co. Carbon All-Road v2 in Sidewinder Black is a T800 carbon gravel bike built on current standards: a UDH hanger, a T47 threaded bottom bracket, 12mm thru axles and a Fidlock storage box in the down tube with the bag included. The finish is gloss black with orange STATE lettering and teal SBC logos, and the geometry is race leaning, with mounts on the down tube, fork and top tube for loading it up.
We sell the Sidewinder Black in its standard build at $2,399.99: State's own 1x12 drivetrain, a 40T direct mount chainring against an 11 to 46T cassette, hydro mechanical disc brakes on 160mm rotors, and State's All-Road v2 alloy wheels on 700c 50mm tires, the Vittoria Terreno T50 or Continental Terra Hardpack TR as State lists them. If you want the 11 to 50T mullet cassette or DT Swiss or Zipp wheels chosen at checkout, the Colorado Blue is the same bike with those options.
Skip it if you want wireless shifting and full hydraulic brakes: the Sidewinder Black SRAM Rival AXS is the same frame for $1,000 more. And skip it if you want a bike that arrives ready to ride, because this one comes as boxed parts that need professional assembly.
Standards you can build on
A T47 threaded bottom bracket, 85.5mm, that threads out at home and does not creak the way press fit does. A Universal Derailleur Hanger any shop can order. 12mm thru axles, 12x100 front and 12x142 rear, flat mount brakes on 6 bolt 160mm rotors, a 27.2mm seatpost and a 31.8mm bar clamp.

A MODERN FRAME, NOTHING PROPRIETARY
The v2 frame is T800 carbon, 1,280g bare on a medium, on a 440g full carbon fork with a hollow 1.5 inch crown and a 12mm thru axle. Cables run inside the frame and fork and outside at the cockpit, so the bike stays clean and the bars stay easy to service.
The down tube carries a storage box with a Fidlock magnetic closure for a tube, tools and food, and the neoprene bag for it is in the box. There are extra mounts on the down tube, fork and top tube, and a molded plate covers the front derailleur mount when you run 1x, which every build here does.

ONE RING, TWELVE GEARS, NOTHING TO FUSS WITH
The drivetrain is State's own 1x12: a forged 7075 aluminium crank with a 40T direct mount chainring, an 11 to 46T cassette and a version 2.0 rear derailleur with an internally adjustable clutch that keeps the chain quiet on rough ground. One ring means no front derailleur to set up or trim, and the chain line stays clean across the range.
Brakes are hydro mechanical: the lever pulls a normal cable, and the caliper turns it into hydraulic pressure at the pads, on 160mm 6 bolt rotors front and rear. Most of the bite of a hydraulic brake, with a cable you can adjust and replace at home.


SBC All-Road 1x12
40T forged direct mount chainring against an 11 to 46T cassette, with a clutch rear derailleur that keeps the chain quiet.

Hydro Mechanical Discs
Cable actuated hydraulic calipers on 160mm 6 bolt rotors. Hydraulic power at the pads, simple cable at the lever.

33 Degree Flared Bars
State All-Road alloy drops, 420mm at the hoods and 500mm at the flared drops, on a 90mm stem.

Room For 2.2 Inch Tires
Ships on 50mm tires with room to go wider: 700c up to 2.2 inch, or 650b up to 2.4 inch, per State.

Questions before buying
Can I get the mullet cassette or upgraded wheels?+
Not on this listing. We sell the Sidewinder Black in its standard build: State’s 1x12 with the 11 to 46T cassette, on State’s All-Road v2 wheels. The Colorado Blue is offered with the 11 to 50T mullet cassette for $70 more, DT Swiss G1800 wheels for $450 more, or Zipp 303 XPLR S carbon for $1,000 more. Every interface on the frame is a standard size, so either upgrade can be fitted later.
How much does it weigh?+
State lists the frameset at 1,888g, 4 lb 3 oz, on a medium: a 1,280g bare frame, a 440g fork, the thru axles, seatpost clamp and bolts. State does not publish a complete bike weight.
What are hydro mechanical brakes?+
The lever pulls a normal brake cable, and the caliper turns that into hydraulic pressure at the pads. You get most of the power and feel of a hydraulic brake with a cable you can adjust and replace at home, and no lever bleeds. Full hydraulic brakes come on the SRAM Rival AXS version of this frame.
How wide a tire will it take?+
State’s product page lists 700c up to 2.2 inch (55mm) and 650b up to 2.4 inch. Their spec sheet lists 700 x 58mm and 650b x 2.3 inch. This build is sold on 700c wheels with 50mm tubeless ready tires: State lists the Vittoria Terreno T50 and the Continental Terra Hardpack TR. There is no tire option at checkout, so ask us if you want to know which yours will ship on.
Does it come assembled?+
No. Unless State’s Pro Build is added, it arrives as boxed parts and needs professional assembly before riding. State’s Pro Build assembles and safety checks it in Phoenix and adds one to two weeks. Ask us before you order if you want it. Pedals are not included.
What size should I get?+
State lists the XS 49cm for riders 5 foot 1 to 5 foot 6, the S 52cm for 5 foot 5 to 5 foot 9, the M 54cm for 5 foot 8 to 5 foot 11, the L 56cm for 5 foot 10 to 6 foot 1, and the XL 58cm for 6 foot to 6 foot 4. Sizes overlap on purpose. Between two, the smaller rides more upright and the larger stretches you out.
