I already have lots of the common goodies - disk, aero front wheel, etc. The only other "splurge" I'm considering right now is ultralight climbing wheels (there are some HILLY TT's and multisport events here), but I think this bar offers more bang/buck for weight loss, vs. what I'd have to spend to drop the same amount of weight on wheels.

Then again, I don't currently have an aero helmet, but after reading a lot of the lashback after the infamous MIT study, I'm not really convinced they do too much. . .
