Wondering the same thing last year. A lot of folks recommend a MTB with slicks for a commuter. But MTB components? I got to thinking (problem #1 ).

I ended up with a MTB frame and brakes, with a street gear train. Since it was a basterd, why not a set of Tri base bars with Barcons? Two rear baskets, and one up front for counterweight groceries rounded out the functionality.

It works for me.....but, you know how that goes.

Commuter all the way.
