Lightweight Structure - At first glance the Birdcage looks like a fairly conventional “aero” style rim, but there is more to it than that. 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. The rim’s 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, GSport was able to to keep the weight down and make the Birdcage their lightest rim available.
Cross-Lacing Strength - The next innovation was to adapt GSport's cross-lacing design to the narrow inner wall of the rim. GSport managed 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’s cross-section, they managed to match all the angles to the nipple so that the walls of the rim section act like the ribs inside the Ribcage rim, which helps to support the spoke nipples as much as possible.
Re‑designed Valve Core - Traditionally, the greatest flaw in “aero” rims has been the valve hole. “Aero” 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. With the Birdcage, they'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.
Easy tire installation and brake pad compatible - Aside from these original features, GSport spent a lot of time “sweating the small stuff”. They've ensured that the deep center allows for easy tire removal and fitting, and we’ve made sure that the sidewalls, while slimmed down, are still suitable for brake use.
Most high tech rim to date - The end result is one of the most high tech rims to date. With a weight of just 440g it outperforms most rims weighing 20-30% more, and the weight saving from the rotational mass of the wheel feels fantastic.

Well made dividers.
Size: 88''W-4 Panel, Color: Grey
Very durable and stable. Once positioned, they stay upright and firm and don't wobble around. Good materials on both the panels and the frame that supports it. Great for any partitioning needs and a fair price for the quality you receive. Highly recommended.

Great quality, very versatile
Size: 6 Panel-132‘’Wide, Color: Beige, Size: 6 Panel-132‘’Wide, Color: Beige
I'm very pleased with this item. It was not complicated to assemble but some items required dexterity and strength. The fabric panels are nice and tight and that's partly why it's a little hard to get that final screw in. I'm very pleased with the legs and the wheels. The metal components are nicely finished and feel substantial and endurable. I can easily fold this so many different ways… I can minimize the number of panels that are seen if desired and it can be straight or accordion. It's very stable which was hugely important to me because I'm fostering many many cats. It's not cheap looking and the light color fabric allows enough light to pass through that it doesn't darken the room substantially. I think the price was very reasonable
