Tire mounting- "Seattle Cycle Service"
Or Seattle Cycle Center", but I think they may be more expensive-IIRC both places are on Aurora ave.
my wife loves her firstgear "Kilimanjaro" jacket-
Seattle cycle center used to have a good selection of gear, have not been there for quite a while.
We use the battery tenders, sort of pricy but not as much as a new battery- the thing to watch out for is not to fry your battery with too much charge- for years I used a 1 amp trickle charger with a timer- one hour a day of 1 amp charge.
Gerbings heated clothing
http://gerbing.com/ is in Tumwater, they have a new micro wire that is supposedly really comfortable- Heated clothing is something that is really nice! And it is a real advantage to be able to go to the factory for and exact fit, as it works best when snug.
