Indeed i did! I might put one on for tomorrow, just so you can all be amazed at my super cool tensioner! If you land on your tensioner, is it just the saw blade you will need to replace? As the theory behind mine was that i dont care if i land on the spoke, as itl bend, then i just bend it back, if it snaps, i got about 200 spokes in my garage. Yours looks better designed than mine though! Is it loud, or does it make a noise at all? Owen Edit: Muel, bend the end of the spoke up, so you can pedal backwards aswell, live in a v shape at the end. Mine occasionally popped off, but it istn really the end of the world when it does, just put it back on! Owen
