Due to circumstances which I'll eventually elaborate on, I'm in the market for a new commuter bike. My previous bike was a short lived Gunnar Crosshairs frame built up with a not-too-serious attitude towards cutting weight. The result was a 27.5 lbs. bike including fenders, rack, lights, pump, 28mm tires, and a disc front brake. While not a tank, I was a little disappointed with the weight when I got done. The almost 2 pound Jannd rack certainly didn't help matters and neither did the 28mm Armadillos. The Crosshairs frame weighed in around 4 lbs. though making it a good candidate for being swapped out for something considerably lighter. I'm hoping to use the same Winwood carbon disc fork.
I've already made up my mind on a wheel build that will cut over a pound, lighter tires that will shed some grams, and I'm almost there on a different rear rack though I loved the width of the Jannd for my Arkel Tailrider (it's just not worth almost a pound of weight over my previous OMM rack). One of the last, and the biggest, things to decide on is the frame. As the title says, I want something that can take a rack and fenders with 28mm tires (hence touring/cross). I know there are some sport road frames, like the Gunnar Sport, that can take 28mm tires and fenders but no one makes a lightweight disc fork for a frame like that. It's no use to me to go with the Sport then add a steel disc fork which weighs close to a pound more than the Winwood. I could get a custom Sport frame built to accept the taller Winwood fork but I'm wondering if there are any better options out there. I realize that I could go all out and have a custom titanium touring frame built and easily get down to 3 lbs. for the frame but I'm not so sure I'm ready to make that sort of commitment (it's also not out of the question though).
So what do you guys suggest?
