Acquired in Trade: WTB Laser V

Through a very timely trade with someone on the MMBA Forum I was able to swap my ill-fitting WTB Rocket V for this new and (very? overly?) shiny WTB Laser V. I’d already ordered a Laser V to try out, but unless this one’s appearance ends up being beyond reproach, I think I’ll be returning it. As can be seen here the chrome and yellow bits aren’t too terrible when taken in context with the yellow bits on the computer and the various silver things on the bar.

Being cloth the cover of this one is also a bit rougher than I’m accustomed to, but that should be okay for now. If it’s not there’s always plenty of other options. At least this one will only cost the $7 or so to ship back the unwanted saddle when it arrives.

Bonding Cut Bicycle Cables

After installing a bicycle cable and crimping on an end cap, removing it usually results in a frayed cable which is difficult to remove and reinstall. For maintenance reasons I want to be able to do this, so I’ve begun looking at methods to seal the end of a cut bicycle cable as is done with factory cuts.

My first experiments with cyanoacrylate glue (aka Super Glue) seem to work well, and when Erik suggested that I solder them, I decided to give that a go. Some research online indicated that a silver-bearing solder works well, so after acquiring some plumbing solder (with silver in it) I gave that a try, and it wouldn’t wet the surface nor wick into my test cable. Normal lead/tin solder for electrical work didn’t work either. I next tried a blowtorch, and while fun it only resulted in ablating the wire resulting in what is seen on the right.

So, right now I think that wetting the ends of the cable with cyanoacrylate glue is the best solution. This is what is shown on the left, and it results in a rigid, solid piece of cable. Disappointingly the cable could be crushed (and promptly frayed) when squeezed with locking the pliers that I use to pretension cables, but this should be acceptable.
