High quality, high stoke

I built my first fixed gear in 1996 and have built several since. I wanted to do a more off-road friendly build this time and decided to give the 4130 frame a shot. I have to say, I’m genuinely pleased with this frame & fork, especially for the price. I’ve paid 4x as much for lower quality vintage frames that aren’t anywhere as functional or sturdy. Highly recommended.

4130 single

Very happy with the frame. Speedy shipping, but the rear dropouts did have some paint chips, was damaged a bit in shipping but not worried about it at all. Especially considering I live in hawaii so the box likely got banged up, however I would recommend reinforcing that area in future shipments to avoid paint chips and damage. Honestly, super stoked to build this frame, nothing else like it in this price range. Great value.

Pretty new 4130

Good value in a frame

I love the purple reign color and design of the fork. Really pleased with the build quality and price of the frame - welds are good and everything appears to be straight. Paint has one tiny little speck on the head tube, but otherwise perfect I’d say. Love riding my new bike after a great buying experience.
