GSPORT BIRDCAGE RIM Black\u00a0<\/span><\/h1>\n
\n

Lightweight Structure<\/h3>\n

At first glance the Birdcage looks like a fairly conventional \u201caero\u201d style rim, but there is more to it than that.<\/p>\n

The first clue comes from the name; birds have hollow bones to save weight whilst retaining as much strength as possible, and the Birdcage rim has a hollow bead for the same reason.<\/p>\n

The rim\u2019s hollow bead is still big and chunky to help reduce the chances of pinch puncturing or flat spotting the rim, but by creating a tiny hollow cavity inside it,\u00a0GSport\u00a0was able to to keep the weight down and\u00a0make the Birdcage\u00a0their lightest rim available.<\/p>\n

<\/div>\n

Cross-Lacing Strength<\/h3>\n

The next innovation was to adapt\u00a0GSport’s cross-lacing design to the narrow inner wall of the rim.<\/p>\n

GSport\u00a0managed to squeeze a few extra millimeters of spoke offset out of the design to help increase lateral wheel strength, and by carefully tailoring the rim\u2019s cross-section,<\/p>\n

they managed to match all the angles to the nipple so that the walls of the rim section act like the ribs inside the\u00a0Ribcage rim<\/a>, which helps to support the spoke nipples as much as possible.<\/p>\n

Re\u2011designed\u00a0<\/span>Valve\u00a0Core<\/h3>\n

Traditionally, the greatest flaw in \u201caero\u201d rims has been the valve hole.<\/p>\n

\u201cAero\u201d rims position a lot of very efficiently utilized mass in the base of the rim to support the spokes and give the rim good strength, then a huge hole is drilled through it for the valve stem and a massive weak-spot is created.<\/p>\n

With the Birdcage,\u00a0they’ve offset the valve hole so that this section can retain its strength. A handy side-effect of this is that fitting a pump is now more convenient.<\/p>\n

Easy tire installation and brake pad\u00a0<\/span>compatible<\/h3>\n

Aside from these original features,\u00a0GSport spent a lot of time \u201csweating the small stuff\u201d.<\/p>\n

They’ve ensured that the deep center allows for easy tire removal and fitting, and we\u2019ve made sure that the sidewalls, while slimmed down, are still suitable for brake use.<\/p>\n

Most high tech rim\u00a0<\/span>to\u00a0<\/span>date<\/h3>\n

The end result is one of the most high tech rims to date.<\/p>\n

With a weight of just\u00a0440g (15.5oz) it outperforms most rims weighing 20-30% more, and the weight saving from the rotational mass of the wheel feels fantastic.<\/p>\n<\/div>\n
