Message: >>I would like to modify a Giant Ocr frame to run top tube cable for shifting, and have been thinking about the best way to install the cable guides: drilling and rivets, soldering (low temp) or using epoxi. Any thoughts? >You can't solder aluminum ... >I would be cautious about drilling holes in an aluminum frame BECAUSE you would want to be careful as to WHERE you did it and HOW you "filled" the hole ... a rivet seems dubious for various reasons. >I would TRY epoxying the guide in place first. >If the guide has a mounting pin, then I would THEN consider drilling & epoxy. >The real question is WHY DO YOU WANT TO DO THIS? >You will need to add at least two guides to the top PLUS one for the seat tube. >The guide/stop on the seat tube will be under a fair amount of stress ... > You might try clamp-on cable stops. This would be non-destructive method of accomplishing your goal, probably much easier, cheaper, less risky, and reversible. Tektro makes them for example.
