I'm in Portland right now. I had a beer last night with Kirk. The subject of track frames came up. I told him that my LOOK 496 was only slightly better than my Tiemeyer. But the Tiemeyer uses standard headsets, stems, forks, & seatposts, which make it A LOT more serviceable!
If I need a new stem from my LOOK, I have to call France. If I need a new stem for my Tiemeyer, I go to my bike shop down the street.
