G-SPORT BUTTED G-SPOKES: A spoke is only as strong as its weakest point, therefore there is no functional advantage in a design where the spoke’s middle is stronger than the elbow and thread. In fact, having a slightly slimmed-down “springier” center section can help to distribute shocks more evenly along the length of the spoke, rather than concentrating them at the ends. Road riders have utilized the advantages of butted spokes for decades, but for BMX there are other factors to consider. The new G-Sport spokes use a butting that is tailor-made for BMX. This is evident in the spoke’s slight cross-sectional reductions, super gentle transitions to the butted areas, and an extended elbow-end to cope with the stresses imposed during grinding. You’ll save roughly an ounce per wheel on 36’s, and the custom butted sections actually allow for a more durable wheel build, rather than a weaker one.

G-SPORT TAPER-HEX NIPPLES: Aluminum nipples have been tried in the past as a way to save crucial “rotating weight” from bicycle wheels, but while the aluminum can be stronger than traditional brass nipples in pure-tension, they are also much softer, and it is all too easy to round them off with an ordinary spoke key. The Taper-Hex nipples use a tapering hexagonal shape to increase the thickness of the metal around the spoke, and the tapering shape also allows the key to slide down easily onto the nipple while also eliminating slop in the interface between parts. The result is a “perfect” connection that prevents deformation of the spoke nipple. The hexagonal head (rather than square) also helps to simplify wheel-building too. The key is designed to rotate in the tight spaces of a BMX wheel and it’s small enough to keep on your key-chain. 36 aluminum nipples weigh 0.6 ounces (16.5g) verses 1.3 ounces (36g) for normal short brass nipples.

The weight savings with butted G-Spokes and the aluminum Taper-Hex nipples are relatively small, but taken together you can save nearly a quarter pound of weight from a typical pair of 36 spoke BMX wheels. Additionally, the spokes will allow for a more durable wheel, and the nipples greatly improve wheel assembly and maintenance.
Instead of shooting plastic into the JC mold, the JC PC was designed from the ground up, with many new ideas and only the JC shape in mind. The pledals have an ingenious way of attaching the body to the spindle. There is no spindle bolt hole. The pedal splits down the center, where the two mating sides sandwich around the spindle. Joining the two sides is achieved by the pins that thread into the mating side with replaceable steel nuts. This style of build creates an ultralight plastic pedal with the durability of an alloy pedal. In addition to weight savings, the grind options are multiplied compared to the metal version.

Interbike 2009 just started today and the first feature up in our flipbook is the Purple Rain Colorway. As with all of our flipbooks, these guys are portable. Click the EMBED button to copy the HTML code you need to post it in your MySpace, blogs, profiles, websites, etc.
There’s one added feature to these flipbooks as well. In the dice, where it says ODYSSEY BMX INTERBIKE, you’ll notice two arrows (you may need to clear your browser’s cache and hit refresh). Clicking these arrows will cycle through all of the flipbooks uploaded for Interbike. There’s only 2 right now but as the day goes on, there will be more to come.
