standard Trek BB90 bottom bracket. Get it at any Trek Dealer. Or take a look at this page for some options

non-drive side you will need "bearing for 24mm cranks"

I recommend the Enduro stainless steel angular contact BB bearings from here: http://www.enduroforkseals.com/id273.html

I was blowing out stock bb90 bearings every 3-4 months, and even less during rainy weather. Since the stock bb90 bearings are chromium steel, they are not resistant to rust and they wear very quickly after any wet weather riding.

I've been on the angular contact stainless bb90 bearings for more than 6 months and they spin better than new once they are broken in (about 1,000 km or so). They do require a bit higher preload to get rid of play but given how they seem like higher quality bearings and are resistant to corrosion I will never run stock bb90 bearings again if I can help it.
