Yes, I've seen that frame. The other thread about the frame, that was one of the features that impressed me about that particular frame. But a majority of frames don't have that elegant feature built in. And I'm sure over the lifetime of the frame, it could have an issue down the road that requires more of a design like this one to replace it ? I see a few design flaws there. One, it looks easy to get at on a bare frame, but working over the chain stays it's not as accessible as from the open and rear of the track ends. Another, it uses hex heads, so can those be stripped out, even the screw or however way that threaded frame end is designed. Nothing's perfect, so for $ 8.95 delivered what I'm getting will do just fine for the lifespan of a Vilano. Roadworthy, inexpensive transportation is the goal here, This bike is perfect in that it flies in under the radar. Plenty of other and more expensive bikes to be stolen before it.

Let's not get carried away here with this talk of replacing perfectly good frames. Let's not throw the baby out after giving it a bath just because the bath water is dirty.
