NuVinci has just added a quick release axle option/upgrade for their internally geared rear bicycle hubs. On the surface, it may not seem like huge news, but here’s why we’re excited: First, it eases flat changes simply because it doesn’t require a wrench to remove the rear tire. One less worry and tool for commuters.
Second, it opens up options for aftermarket trailers. With many commuter bikes now coming disc-brake equipped, trailers and child carriers that clamp or strap to the chainstay or seatstay simply won’t work (the clamp usually interferes with the rotor and/or caliper, and if you mount it too far forward your heel hits it). And unless you’re committed to pulling an axle mounted trailer or other appendage full time, most of us simply aren’t willing to bolt/unbolt the rear hub every time we want to attach something; we just grab a different bike. But, we have a lot of bikes to choose from. Most cyclists have one commuter and rely on it for everything. A quick release means they can now quickly pop in something like the RideKick or other axle mounted trailer.
