        Thunderbird Gravel/Cyclocross bike where afford ability & versatility shine brightly

        After doing the research looking for a single speed gravel/cyclocross bike that was both affordable and easily upgraded, I decided to go with the State Bicycle Thunderbird. I spent my money on this bike and these are my observations.

        The bike came ridiculously fast, 2 days from Phoenix to Denver! It was a straightforward build, it came well packed and there were no issues putting it together. While assembling the bike I noticed there was some paint chipping off near the rear dropouts, but that was luckily the horrifically colored pink which I planned on painting anyway.

        The components are decent middle of the road quality. I purchased the size 55cm, it came with 40cm bars and 170mm cranks which are too small for that size bike. I swapped them out for 44cm wide bars and 175mm cranks. The bottom bracket is high enough, there is no reason to go with such short cranks. The seat looks nice and seems to fit my butt, I realize that is subjective though.

        The bike isn't light, but isn't a tank either. A few things that would drop some weight: A good quality tubeless wheel set (with lighter folding tires), better quality crank set, swap the BB5’s for BB7’s (more adjustable, sealed from the elements and lighter), swapping out the 1/8" chain for for a 3/32" and a carbon post would improve ride quality and drop some weight.

        I now have almost 200 miles on my Tbird and the bottom line is when asked the question "would you buy it again?" and the answer is yes, I would buy it again.

        (Should be a 4.5 star review)

        Pros-
        Industry standard 135mm rear & 100mm quick release wheel spacing
        Lightweight aluminum frame & carbon fiber fork
        Eccentric bottom bracket for chain tensioning
        Good quality Ritchey Logic components
        Sram/Avid brakes & levers
        More than 1 water bottle mount

        Cons-
        Heavy non-tubeless, no-name rims laced to low end Joytech/Novatec hubs
        Narrow 40cm bars on the size large frame
        Short 170mm and heavy no name crank set
        Obnoxious color choices

        Purchased this bike in may, I’ve been racing it and beating crap out of it for 5 months now. 2-300 miles in (mostly a cx race bike ) and this thing hasn’t missed a beat. I’ve had no issues and only replace a chain and brake pads.(northeast cx races get muddy) the bike is a great entry level race bike or even a gravel bike to rip around your local paths and roads your afraid to take your road bike down. You can’t beat the price point on this bike esp. with the ritchey components. 10-10 but this bike and do rad stuff!

        Thunderbird

        Upon arrival, this bicycle explodeded it's way out of the box and sprang to life like an anthropomorphic vehicle from a Michael Bay franchise. In no time(very minimal assembly required), I was absolutely crushng my local streets like a killdozer. I got arrested for property destruction by municipal law enforcement, but there was Thunderbird, waiting at detention to bail me out. After a few beers and laughs, I commented on the Thunderbird's sexy lines and rock solid build, which led to an all night ride. This one's a keeper.
        I'm 5'11" and the 55 fits great.
        Fast shipping and good customer service.

        Sleek but

        Great looking, easy build, but the hub on back wheel has issues after 4 rides, already has side to side play and something clanging around inside the hub. Kind of a bummer.

        Great Bike

        Bike was shipped insanely fast and was up and rolling within a day. Love the ability to use it as my main commuter as well as take it up some hills and dirt paths with no issues. As with any new bike I had to break it in and adjust it a bit, but everything is working flawlessly now! Looking forward to all the new adventures we'll be going on.

        BB anomoly

        On the whole, I really like the bike. I immediately swapped out the tires to shake the bike down on some road rides to get a feel for how it handled. I was a little disappointed that after about 70 miles of riding, a very annoying creaking sound developed and I quickly determined that it was the BB. When I finished the ride, I had to extract the crank set and removed the non-drive side BB cup which seemed to be torqued pretty well. When I put the tool on the drive side cup, it was loose to the point that I was able to remove it by hand. I put a little bit of lube on the threads of both sides of the BB and re-installed the cups and crank, all was good on my next 30 mile ride. I guess if someone who doesn't have the tools or knowledge to troubleshoot the creak, would have incurred additional cost taking the bike to a shop for such a simple issue. Cheers

        I love it

        I’ve put about 100 miles on the bike so far and I really love it. Easy to put together, and all of the pieces feel great.
