[Yak] Heat detection devices and Do I need a new tandem

[charles voigtsberger]

I looked up the product and what you need to determine if your rims are too hot is a product called Tempilac. It is made by the Tempil Corporation and will melt at pre-specified temperatures. When you reach that temperature it melts. So you just need to paint your wheels with the Tempilac for the desired temperature you want and when it melts you need to let the wheels cool down. Reapply the Tempilac and continue on down hill.

Amy, you don't need a new triple (that is unless you are trying to justify the purchase of a new triple and then that is a whole different topic.) With the style of riding you do, the triple you have is fine and is safe. I indicated to you before that if you decide that you want to take trips with it where the terrain is steeper you might opt for a drum brake. If your children get bigger quicker than you anticipate, you might opt for a drum brake. In fact, if you have a son and he gets significantly bigger and stronger than you are, you might want to switch and have him as captain. If you are happy with the stopping power of your triple as it is presently configured, stay with it. You know whether you can stop where you want to stop. You know whether your bike's stopping power feels adequate. On the other hand, if you are uncertain whether you are going to stop on this side of the intersection or the other side of the intersection. If, every time you
 clamp on the brakes you wonder if you are ever going to stop, then obviously you need to consider a different braking system. But as long as it feels secure, it most probably is. My first tandem had old Marfac brakes on it and I was never sure where it would stop. I knew it would someplace, some time, but exactly where and when was always in doubt. I replaced those old brakes with a used hydraulic braking system and was very happy with it. We always stopped exactly where and when I wanted to. It cost me about $100 for the used hydraulic system and it was money well spent. Hope that answers your questions about the suitability of your triple.
