I bought some Profile Design T2 clip-on aero bars today. I got them off craigslist for $50 (plus one dog bite when I picked them up - small dog, no damage). I put them on the Tricross and in the initial position I think they will be pretty comfortable. They are higher than the drops, so I think I'll be able to lower the bars as far as practical in the drops and then be comfortable on the aero bars.

There is just enough room between the brake cables. I may have to take off an inch of handlebar tape on each side to get the cables off of the aero bar bracket; I'll see when I get them fitted a little better. I really don't have much use for riding in the tops anyway, the only time I do is when I'm exhausted after a climb or a sprint.

Now I can get an Aerodrink or Aquacell water bottle to fit between them. These have a straw so I can drink without sitting up - this should be very nice.

To recap, yes I am aware of the Fred-ness of my bike:
- cyclocross bike
- 32mm tires
- fenders
- clip-on aero bars
Just wait till I get the rack on there!
