Crupi Frame

Each of our frames are designed for a specific size need and the geometry of that frame is suited for that size rider. In other words, we didn’t design a frame we liked, then size it to fit everyone.  We don’t add any fancy gimmicks to our frames, we just make quality frames that work and work well! Most importantly, unlike a lot of frame companies out there, we have our frames in stock when you need them. 

If this alone does not convince you that our frames are the best there is, then continue reading below for more technical info about our frames, then you will know for sure!

General Frame Information

All Crupi frames are built with seamless drawn 6061 T6 tubing.  Very few other frame companies use this type of material because it is more expensive.  What does this mean to you?  The cold reduction process of our tubing improves dimensional tolerances and simply makes a stronger frame.  The material is so good that each material run comes with quality certification sheets that show that the material was tested for mechanical properties and an aluminum chemical analysis. 

All Crupi frames feature this seamless drawn material which is ovalized at the ends to provide more welding surface. The chain stays are ovalized at the bottom bracket and rectangular at the dropouts in order to provide more stability in these areas. The axle slot in the dropouts is parallel to the ground meaning no matter what position your rear wheel is in; the frame geometry will not change. All Crupi frames come standard with Euro style bottom brackets.

Frame Sizing is critical to making your frame work best for you.  When comparing other frames to the Crupi frame, forget what you’ve heard about top tube length since that wont provide accurate information.  Please click on our frame sizing link which will show you how to properly measure a BMX frame to insure you get the best size.
