      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).

      How Pro-Build works · Find a shop near you

      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.

      Start a return · Full return policy

      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.

      Galaxy seat post and handlebar!

      I purchased these for my 14 year olds daughters Trek Marlin7. They are a little heavy but this build is more about fun! She is all about shredding dirt and bright colors. I’m a 1st 3rd and 5th dad so I texted her a picture of the bike once I had these is installed, she had no idea as it was part of her birthday present. She immediately texted back about how these bars and post were absolute FIRE. Once I picked her up from her moms and brought her to my house I constantly caught her in the garage admiring her bike with a huge smile on her face. Once on the trail she had to make her way around the parking lot showing off how cool the galaxy colored bars and post looked on her bike. She loves the width, rise, and angle of the bars. Thanks for making an affordable oil slick colored cockpit for people who live oils slick!

      Looks “Slick” (Pun Intended)

      This seat post looks FANTASTIC.

      The finish is amazing, and the SBC logo etching is really well done.

      I really can’t say enough about how spectacular it looks. Included hardware is top notch, too.

      If you think the scheme will fit the colors you’re going for, by all means pick this up!

      Slick!

      Good looking post. Giving the fact that it’s alloy it is still pretty light weight. Recommend!

      Oil Slick seat post

      Well machined, great colors, great price point. Wish there was a 25 or 30mm set back version.

      Sitting on a galaxy…

      The post is exactly what I needed to add a little bit of bling to my All Road and it had a zero offset!! I was looking at Thompson posts. They are nice but you pay for it. This was half the price and State Bicycle Co branded. Moved me forward right into my hoods without stretching my arms straight! Score! I think with a 10-20mm shorter stem I’m gonna be in the sweet spot. The oil slick anodizing is top notch. I’ve seen some sloppy anodizing since the “jet fuel, oil slick, rainbow” parts craze. My favorite slang I’ve heard so far is “unicorn poop” hahaha. The two bolt, micro adjust clamp works great and the gold hardware is a nice touch. I figured for the price the hardware would be second string. It’s not. All in all for the price, weight and function it’s a win. I’d say it’s a little lighter than the stock post on the 4130. The slots ant the bottom give it a paintball gun barrel aesthetic. Add the eye catching oil slick anodizing and it’s a win win!!

      Nice

      This is a nice, well-designed seatpost, just as expected. The head micro-adjusts and is very easy to set just the right seat angle. The lower seat rail tray is extended length, a nice touch for extra support if you want to slide the saddle rearwards instead of centered over the post (or have long rails like SMP saddles). The finish is nice, although not the high lustre like their oil slick handlebar; the seatpost has a fine ribbing, not a mirror polish. It still looks good, but if I had my druthers, I’d like it to match the handlebar exactly. In all, I’m very happy and enjoying the extra pop of color the post gives and feel more confident in SBC than buying a generic post off eBay from a shadowy, foreign vendor.

      Out of this world!

      Love the color. Great addition to my classic galaxy edition fixed gear I got back in 2015. Thanks state.
