This has been an outstanding piece of gear. I have riden with it year round with no failure, in fact it registered to 0 degrees F. If you already know your layer chart this will allow you further clarity and layer adjustment.

Stem Captain Compass Rating:

Very disappointed. The compass worked correctly when out of the stem cap. But immediately upon insertion, the compass stopped using magnetic north and started using the magnetic attraction within my bar, fork, or stem. I was always headed north!

This is my second Stem Cap (clock both times). The first one popped off whenever I hit a bump or rough road. No matter what I did (including putting rubber cement underneath the clock in an attempt to glue it down) it still removed itself from time-to-time. Thus far this one has stayed put!
