Hi Gernot, I did not have a basket on that bike and there was no visible wear on the plastic coating of my housing. However, I'm sure wear like yours certainly doesn't help. Perhaps you could try putting a little bit of heat shrink tubing (can be found in the electrical dept. of hardware stores) on your replacement cable housing to protect them at that wear point. I also think you're on the right track with that washer on your shifters. Way to kick that problem in the pants! By the way, I've admired your photo sets in the past. Beautiful! I'm jealous of your local. How do you feel about visitors, haha? Best, Travis On Mar 22, 3:14 am, Earl Grey wrote: > Travis, > > thanks for the info. Do you have a basket on that bike?

[RBW] Re: Gray Shimano derailer cable housing busted
Travis, thanks for the info. Do you have a basket on that bike? Upon closer inspection, I believe that contact between the housing and my rattan basket caused the plastic to wear through which caused the rupture. See a photo of the other spot where the housing contacted the basket: http://www.flickr.com/photos/gernothuber/5548985681/ I will replace the right side housing shortly, since it shows the same wear. I also swapped and turned the washers that came with the Silver shifters so that the little hook now prevents excess lever travel: http://www.flickr.com/photos/gernothuber/5548985783/ Cheers, Gernot On Mar 22, 1:44 am, Travis wrote: > Oh oh oh!

I'll send you my address, and you can mail me the takeoffs! :^) If only I could remember who it was who said they throw their Marathon Supremes away after three flats... I only have one bike with derailler cables, but they've been on for 3 or 4 years, and the ones before that outlasted the shifters (6 years). Mountain bike - mud, sun, freezing cold. Rain. I'm of the mindset that "if I can remember buying it, it's new."

[RBW] Re: Gray Shimano derailer cable housing busted
Oh oh oh! I had exactly the same thing happen in the exactly the same way with some brand new Jagwire derailleur housing, I mean exactly. I believe it just has to do with the way derailleur housing is built. The strands of wires inside are all running parallel to the cable, and if you put enough tension on the cable at a bend it will pull through those strands in order to straighten itself. To prevent repeat episodes, I set my front derailleur shifter up so that it is physically restricted by the shifter pod at the exact point at which the front derailleur is hitting the limit screw for the big ring. So, when I'm in the big ring my bar-end shifter is pointing upward, and when I'm in the small ring my shifter is parallel to the ground. I don't think it looks quite as nice this way, but I got over it quick and never have to worry about busting the housing. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Gray Shimano derailer cable housing busted
Gernot: It sounds like an unusual event that will probably not repeat. One of my touring buds had his housing split but he couldn't recall how long they'd been in use; many years at the least. My '03 Atlantis still has the original shifter cable housings. They have integral ferrules at each end. You're in a pretty intense sunlight & moisture environment compared to most of the US. Unless it's readily available locally, you guys might want to agree on a color & stock up as long as you're ordering. Funny, if you keep some parts around, the ones on your bike will live for years. dougP On Mar 20, 10:55 pm, Earl Grey wrote: > Hi, > > yesterday, as I shifted my Sam with alacrity into the big chainring, > the left silver shifter went past the limit of its range of motion > determined by the derailer limit screw.

[RBW] Re: Gray Shimano derailer cable housing busted
Gernot, Brake housing is fine for friction shifting, even bette rif it is what you have on hand. I would guess that many here are old enough to remember the "slinky" housing that came with Suntour barcons. Even super cheapo brake housing is probably beter than that. Yes the furrels wil be bigger but they just but up against the shifter and should fit into your downtube stops OK. FWIW I have been running brake cable as shifte ron the Roadeo for a year and a half now, I wanted to use the brass furrels all around Rob - http://oceanaircycles.com/ On Mar 20, 10:55 pm, Earl Grey wrote: > Hi, > > yesterday, as I shifted my Sam with alacrity into the big chainring, > the left silver shifter went past the limit of its range of motion > determined by the derailer limit screw.

[RBW] Re: Gray Shimano derailer cable housing busted
Never happened to me before, but I shift with care and caution..hehe Was there a kink in the housing or any sign of a sharp bend? I had a similar case coming out of a Shimano brake/shifter.But it was some silver Jagwire housing. That's one reason I tape my cables along the bar because I don't like to have cable hanging out where they have more chance of getting twisted or kinked. ~Mike On Mar 20, 10:55 pm, Earl Grey wrote: > Hi, > > yesterday, as I shifted my Sam with alacrity into the big chainring, > the left silver shifter went past the limit of its range of motion > determined by the derailer limit screw.
