0200 hrs Shimmy onset.
Went to the 24 hours store today at 0200. On the way back on a downhill run I hit an expansion crack on the road the bicycle began to shimmy really badly.
At first I thought I'd punctured. Got stopped safely and felt the tire. it was still hard. Checked the spokes and none were broken. Wiggled the rear rack to see if it was looses or broken. Nope but the rack did move. Took the light off the front and shone it at the bike. Oh BOY! Lookie here to see what caused that shimmy. https://www.flickr.com/photos/738325...n/photostream/ Really glad that the entire back end didn't come off! I guess this bicycle goes to the scrap heap after I strip off all the usseable stuff. Cheers |

You can see the seatpost through the holes where the seatstays used to be. Cheers |

You can see the seatpost through the holes where the seatstays used to be. Cheers I assumed that the Phoenix Ditch Pig name was your satirical invention, like the Nameless Cycles (not my idea) home-made decals I stuck on a couple of my bikes. The frames of those weren't quite extracted from a ditch but they did come off the garbage tip. Something made me google the Phoenix Ditch Pig and I was astonished to learn that the brand really existed! Your photo reminds me how small the welds are when designers use the classic seat stay decoratively bevelled at the top and tacked to the sides of the seat tube or the seat tube lug if there is one. I just made a quick survey of my herd. All but one use the probably stronger arrangement where the seat stays are butted to the rear of the seat tube with a weld all round the circumference of each stay. One of my tip queens, a GT Avalanche 3.0 rain bike uses a more complicated seat tube cluster design. http://tinyurl.com/pxnrafz It seems to be a feature of GT hardtail MTBs and road bikes to this day. Not an original idea of course. Many bike builders used it before GT ever came on the scene. PH |
