TNT C-Four Frame (100% Made In USA)

Race proven, track tested. These are things you will hear when shopping for a new frame.  Although our frames are both those things, we take great pride in the fact that since 1985 TNT frames have always been 100% US MADE.

The TNT C-Four frame has contributed to several national, and world championship titles ever since it was originally introduced back in the day.  Our trademark design is aesthetically pleasing as well as functional.  Starting with our trademark loop tale design, which not only looks different and amazing, but also provides superior stiffness, and strength.

Next we have the split seat tube, which provides enhanced acceleration in quick twitch applications such as gate starts & whipping out of corners. To keep your front end tight and solid, we have provided not one, but two gussets on the top & bottom.  Each gusset features a laser cut out with the TNT name, just in case you could not tell what kind of frame this was already.  Each frame is constructed from only the finest 6000 series aluminum, and heat-treated within specific tolerances.

For 2015 all TNT frames feature an integrated headset system, and European bottom bracket.  With 16 sizes in the works, you will have no problem finding a TNT frame that fits your needs.
