About This Product
The Crupi 2017 BMX Race Frame-Crystal Chrome features the same great tubing as the 2016 model, but with all new updated measurements.
This all American made frame is constructed of high grade 6061-T6 Aluminum and features a butted top and down tube. These butted tubes maintain the frame strength and stiffness at the headset and bottom bracket while cutting down on weight. And, yes, it is a powder coat paint and not a normal chrome dip! Shaves the weight and won't rust/peal like the traditional chrome applications.| Frame Size | Micro | Mini | Junior | Expert | Expert XL | Expert XXL | Pro | Pro XL | Pro XXL |
