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 405mm chain stay, a 45mm fork offset, a 50mm bottom bracket drop and a 170mm crank, so the handling stays consistent across the range. State publish rider heights of 5 foot to 6 foot 2 across the four sizes.

Core-Line Overview
The State Bicycle Co. Core-Line in Wulf is a hi tensile steel fixed gear and single speed bike from $449.99. State call the Core-Line what they are best known for, and they back the frame and fork with a five year warranty. It weighs 24 lb 8 oz in a 54cm on their own figure.
It is geared 44x16 on a sealed bearing flip flop hub, and both cogs come with it: a 16T freewheel on one side and a fixed cog on the other. Platform pedals are included, the brakes are fitted front and rear before it ships, and the grips are the Cult x Vans waffle pattern. The frame carries rack mounts on the seat stays and eyelets on the fork.
You choose the cockpit at checkout. Riser bars are the standard build at $449.99. Bullhorn bars and drop bars are $25 more. Skip it if you want gears, discs or a chromoly frame.
Standards you can build on
Every interface on this bike is an established size. 27.2mm seatpost, 68mm English threaded bottom bracket, a 130 BCD chainring, 100mm front and 120mm rear spacing, and a flip flop hub threaded for a standard freewheel. State back the frame and fork with a five year warranty.

HI TENSILE STEEL, BUILT TO CARRY
The frame and the fork are hi tensile steel. It is the heavier of the two steels State use and it is why this bike costs less than the chromoly 4130, but State still warrant the frame and fork for five years. Complete bikes run from 11,406g on a 46cm to 11,870g on a 58cm on their spec guide.
What the frame adds is mounts. There are rack mounts on the seat stays, eyelets on the fork and cable stops on the frame, so a rack or a set of fenders bolts on rather than clamping around a tube. The dropouts are horizontal with integrated chain tensioners, which is how you set chain tension without a derailleur.

THREE BARS, ONE BIKE
Handle Bars is an option at checkout, and unlike the rest of the State range it is not free. The 570mm riser bar is the standard build at $449.99 and comes with the Cult x Vans waffle pattern grips. The 420mm bullhorn and the 450mm drop bar are $474.99, and both come wrapped in bar tape instead.
All three run the same frame, the same 90mm steel stem and the same dual pivot calipers, so the only thing that changes is where your hands sit. Risers put you upright for traffic, bullhorns give you something to pull against out of the saddle, and drops give you a low position and more places to rest your hands.

Questions before buying
Does the Core-Line come with a freewheel, or only a fixed cog?+
Both, and neither is an extra. State ship a 16T freewheel and a fixed gear cog, one on each side of the flip flop hub. Ride it fixed, or flip the rear wheel around to coast. Platform pedals are included and the brakes are fitted front and rear before it leaves.
Is the Core-Line frame 4130 chromoly?+
No. State build the Core-Line frame and fork from hi tensile steel, which is the heavier of the two steels they use and the reason this bike costs less than the 4130. State still warrant the frame and fork for five years. If you want chromoly, that is the 4130 at $579.99.
Do the three handlebars cost the same?+
No, and this is the one State bike where they do not. Riser bars with the Cult x Vans waffle grips are the standard build at $449.99. Bullhorn bars and drop bars are $474.99, so $25 more, and come wrapped in bar tape. The frame, stem and brakes are identical on all three.
How much does the Core-Line weigh?+
State list 24 lb 8 oz for a 54cm on their product page. Their spec guide gives the full range in grams, from 11,406g on a 46cm to 11,870g on a 58cm. The two figures do not quite agree, so both are given here rather than averaged.
Can I fit a rack or fenders?+
Yes, and it is one of the reasons to pick this bike. State build it with rack mounts on the seat stays, eyelet mounts on the fork and cable stops on the frame, so a rack or a set of fenders bolts on rather than clamping around a tube.
What is the widest tire that fits?+
It ships on Kenda 700 x 28c tires and State list 28c as the suggested maximum. They note that riders have fitted up to 32c, but fitment varies with the tire brand and the wheel. This is a road width bike, not a gravel one.
What size should I get?+
State build four sizes covering riders from 5 foot to 6 foot 2. The 46cm suits 5 foot to 5 foot 4, the 50cm 5 foot 4 to 5 foot 7, the 54cm 5 foot 7 to 5 foot 11, and the 58cm 5 foot 11 to 6 foot 2. Sizes overlap on purpose. Between two, the smaller rides more upright.
