Are you still running the stock cranks? The stock cranks on the Kilo TT (Truvativ Touro) are not square taper. They're Powerspline.
As others have said, a $100 bottom bracket is way overkill. Tange and Shimano make quality square taper bottom brackets in the $20-30 range.
I run a Shimano UN54, and despite having been beaten through a couple winters and having a plastic non-drive side cup, its a good buy for $20.
Edit: I just saw your other post in the carbon crank thread. I also run 75s with the Shimano UN54, despite the fact that the BB is JIS taper and the cranks are ISO taper. Another option in the "cheap" price range is the Protype 75 BB:
yes i badly need a replacement bottom bracket. the one i have is totally shot and grinds really bad. and yeah it is a little overkill but i would like to ride on a carpet that i don't ever have to worry about replacing for a long time. and no i'm not going to use the stock crank, i'm looking at replacing that as well.
Based on your posts about carbon cranks and ti BBs, it seems like you are trying to lighten your bike...by throwing money at it.
This is NOT the way to do it. Putting carbon cranks and a Ti BB on a Kilo is like an overweight bike racer putting titanium bolts on his bike to make hill climbs easier. There is a huge elephant in the room that isn't being addressed here...the KILO TT. Carbon cranks and a ti BB won't put a dent into how heavy that bike feels. It's the 4130 (or whatever it is) steel frame that's heavy.
If you want a light bike, start with a light frame, then light wheels, THEN look for lighter components.
The frame doesn't have to be carbon. You can find a decently light aluminum frame for not a lot of money. You can buy/build some lighter-than-normal wheels for a moderate amount.
The key is to have an idea of where you want to go with this, save money, lay a foundation, and make it a long term project.
You don't have to buy the lightest of every part, either. There is a point of diminishing returns when you buy a-la-carte.
I know all of this because (years ago) I set out to make the Lightest Flatland Bike project bike for RideUK (BMX mag) and made a super-light bike that was featured in the mag. It had a Ti BB. It was freakishly light and not fun to ride.
