Redline introduces full carbon BMX frame

Redline Bicycles recently came out with quite the innovation in BMX frames. Redline makes all kinds of bikes; a formidable cyclocross frame, the Conquest, and a solid entry level single speed mountain bike, the Monocog and Monocog 29er. It also has a has a long history in bicycle motocross. 




They recently rolled out a full carbon BMX frame called the Redline Project 79. This is a pretty big step for an industry that has a self described technology ceiling. If you can't improve on the simple yet very effective frame design, improve the materials.

The weight is the amazing factor with this frame:  1 pound 1.3 oz 

Compare that with some other race frames:
Supercross Envy V2: 3 lbs 1.2 oz
GT Speed Series Race: 3 lbs 10.5 oz
Intense Podium Frame:  4 lbs


A couple noticeable features of this bike: Giant tube unions. These joints are over-sized to stiffen up the bike. A carbon frame without these considerations would have far more flex than desirable. With these over-sized connections, it's certainly expected to be stiff.

Also, you may have noticed that the frame has closed dropouts. This means that you have to run a specific kind of hub and axle, called a 'thru axle'. This axle is 15mm, and works similar to a quick release, although much stiffer.

It's very exciting to see innovation from a company when BMX racing is not nearly as popular as single speeds, road or mountain. I'm stoked on Redline for stepping up and putting the r&d into something like this. Oh, and the name, Project 79? The 79th element of the Periodic chart: Gold. See you in London, Redline!
