Radfest of a bike

This bike is an amazing Tracklocross bike so much fun with some wide flat bars. Great you can fit up your 45s easily in the rear and on the fork can sometimes get a 2.2 depending on the tire. Super rad and at a great price!!!

Love IT!!!

State nailed this frame! What's not to like? Enough clearance to allow you to get a bit of off-road fun in. Cool colors, you name it, it's a dope frame. Add fast shipping and the best warranty in the business, and it's a no-brainer. Just get it

Fun

Super juiced on this 4130 build since its my first full assembly from all seperate components. 59cm frame and all parts could be found from State site. Tools not included obviously (and whats a warranty haha) but such a fun way to establish even more confidence with the State brand bicycles. Highly recommend! 😎🔧⚙️🚲

"Olive" this frame!

Built a freewheel SS for my college grad girl. Paint job is great and the quality build of the frame proves steel is still real.

Single Speed With Style

I purchased this frameset to build something for just around the neighborhood. After the first week, I find myself riding 20-30 miles every time I go out. It's built up with State SS wheels and is an amazing ride. It takes the gravel paths and light trails just as well as the pavement. 200 miles in the first week and I haven't missed having a rear derailleur. It's lightweight, spins up fast, and holds speed very well.

Great frameset for the $$&

Really enjoying my 4130 single speed! The quality of this frameset has truly exceeded my expectations. There were some low hurdles to overcome with my build, however. The frame shipped with a free headset that I didn’t expect much from other than for it to work. The baggy it was packed in broke open and its contents were spewed throughout the box. Bearing cages were bent and balls were lost. The headset also seemed to be missing a dust/debris cap. No biggie as it was a no cost item. Was able to pick up a FSA Orbit on the cheap from my LBS. While the frame was packed very well, the headtube did arrive ever so slightly out of round. Pressing in the new headset seemed to rectify the blemish without issue. The only minor gripe I have with this frameset as shipped is the limited steer tube length of the fork. Totally understand the convenience of your choice to generalize AND install a star nut, but, my old ass could have used another 50 mm on the tube to help level the cockpit and would have welcomed the option to hack it down if necessary. All in all, very happy with the frameset! Definitely checks a lot of boxes that don’t even exist in similar options: multiple mount options AMPLE tire clearance, etc.. Thanks so much! Look forward to enjoying for years to come!!

Good stuff

Ordered the 55cm 4130 ss/fixed steel frame in olive green and I love it. Paint is flawless, beautiful craftsmanship and really nice details like the chain tensioners and the finish on the fork and wishbone cutouts. So far the build is coming together nicely. Can’t wait to go shred on this beast!

Super cool

I had a bunch of spare parts from other builds. I got a frameset and a wheelset. Bobs your unkle.
