Bicycle Mechanics - 2010 Madone 4.5 - English or Italian Bottom Bracket?

I'm slowly "upgrading" my 2010 Trek Madone 4.5 from 105/no-name Shimano components to all-Ultegra components. Is the bottom bracket Italian or English threads?

A search of the applicable keywords did not show any results.

I don't know anything about the bike and I haven't even googled it, but I'm willing to bet good money that it's english threaded.

It's english.

According to Trek's site it's neither. It uses pressfit radial bearings.

Lol

Duh! I remember reading that somewhere last year. I was asking so I wouldn't purchase the wrong thread BB. Sheech! I'm having to learn bicycle wrenching all over again. Previous to purchasing my Trek last year, and the Kestrel about a month ago, I was riding a early 70's vintage Mondia Super. It has served me well over the past forty years, but my lady friend convinced me that I needed to "upgrade" if I wanted to keep up with her. Heck, what did I know? I knew that the old Mondia was comfortable; I've changed most of the parts myself, and that I couldn't climb on the thing. Being taller than average, I just figured that what "they" said about big guys not being able to climb were true.

Well, I got that Madone and what a shock! Except for how the seat attaches to the seat post, everything else has changed. I'm having to learn wrenching all over again. The shop where I purchased the Trek refused to install my old, 40-year old Brooks saddle. I love that old thing, and it fits my rear end perfectly. Kinda heavy by today's standards, but very comfortable. After one short test ride on the Trek with the OEM saddle ... it was gone! And on went the Brooks.

It will take me a while, but I'm really loving those new carbon bikes. I can actually climb now without embarrassing myself, especially on the Kestrel. That thing is like a mountain goat and I almost believe it can go straight up the side of a canyon ... except for the gearing, which I'm sorting on in a different thread here.

Thanks for the help. Ride safe. (That's what us Vespa riders say to each other all the time. Also, "watch out for the cagers".)

If you want to keep up with her you need to work on the engine! :speedy:

Hah! So true. I've been working on a tune-up, but the parts are pretty worn out; probably salvageable though. I've got the advantage now because she's having hip/spine issues and can't ride much. We became acquainted through a mutual friend to become "bike buddies". It's become much more now, but we still joke about "just being bike buddies".

The bike can be handy in the mating rituals. Hope she is better soon. I have had back surgery and it is better,but it will never be as good as it was. Old age sucks.

That's ridiculous.
