Just thought I'd chime in with a second (slightly biased) vote for the
Steelwool Tweed.
It's actually Tange Prestige tubing this year, not 4130 like last year. Full braze-ons for all sorts of fun. Big tire clearance (700x44 shouldn't be any problem at all).
Redbike in Edmonton is stocking them, no one in Calgary yet as far as I know.
I should let you all know, I do work as a Rep for Steelwool, so I'm a touch biased. But at least you can ask me any questions if you have them...
