Where to buy bar end shifters I would really like to pickup a pair of bar end shifters but none of my local bike shops are able to get any for me.  My local bike dump laughed in my face when I asked them where I should/could find them.

Where online could I get some bar end shifters for a reasonable price?  (Bonus points for cheap shipping to/in Canada).
The first place I look for 'unusual' parts is Loose Screws. They have Ultegra and Dura Ace bar end shifters available.

My second source is Rivendell Bicycle Works - They have a couple of different options.

Not sure what you consider a reasonable price, but $100 US seems to be the ballpark for new shifters.

Finally - you can always try eBay for used parts, but that is hit and miss for both quality and selection when dealing with more obscure parts like these.
