Invest Cast Dropouts
Because the dropout is cast as one piece it's much stronger than a plate welded to a tube. 7mm thick to provide good support for your axle, and the small shape has been designed for grinding meaning there's no overhang to catch on ledges or rails, also the dropout is heat treated before welding making it extra tough. And finally there;s an integrated chain tensioner bolts inside.
The Raider frame is a tall frame with a big standover and because of this it also has a taller headtube to keep the frame angles looking nice. The taller headtube distributes stress at the front of the frame over a larger area and also means you can run your stem and forks with no headset spacers for a cleaner look up front.
On a frame the highest concentration of stress is at the junctions between the headtube/toptube and headtube/downtube. To handle the pressures of modern riding, the required strength is achieved by beefing this area up using a combination of butted tubing and external gussets.
