WhiteSilvio Cable Issues
Hi Doug,
Finally found the time to post a reply.
Doug asks "Do the cables on your Shimano brifters exit the side of the brifter, or are you using the newer brifters that route the cable back along the handlebar?"
Mine are the older style of brifters which exit the side of the lever.
I include 2 pictures of the current cabling; a front on view and an overhead view looking down on the cables roughly parallel with the cables.
When I replaced the last cable I added a little more length to the outer cable to allow for just a little more space for knee movement and allow for a bit of movement if I decide to move the 'bars. I really don't think it effected the run of the cable into the STI lever to any significant degree, but it may make a difference. Who knows?
I also include a picture of the almost broken through cable that I replaced. I think it shows that the cables have broken in one spot in particular but whether this was the first break or last I cannot say. I guess monitoring the cable by eye every now and again might throw some light on the first signs of breakage. I usually know there is something happening because the shifting becomes a little erratic and not long after the cable breaks. (The second last time I took the bike to my LBS and said I wanted the cable replaced and the mechanic told me that the the gear change was just out of adjustment. While he was adjusting it the cable broke!)
I have the same Ultegra STI levers on my old LeMond and for the relatively short time I rode that, about 11000km over 18months, I also had problems with the change cables breaking in a similar manner. Maybe I just do more shifting than most?
I decided to see when I had broken the cables and when I went through my LeMond and Silvio records I found I was only getting about 5000km out of the cables (both front and rear derailleurs), so I start to get nervous when approaching this mark on my ride spreadsheet.
Doug asks "Do your cables bend right out of the brifter, or do you have a short straight run before letting them curve?"
I reckon that they come out fairly square, perpendicular to the lever.
Well enough from me.
