Welcome to the Trek family. As a (pretty obvious) fan of the manufacturer, I have my share of experiences with BB90. Some of those experiences are good, many, are not.

As mentioned above, the BB90 NDS bearing is prone to failure. You would be best served to keep several spare bearings, as you will be replacing them due to water ingress. Don't bother splurging for expensive stuff, either - they rust all the same, and unfortunately, none of the major bearing manufacturers (NTN, SKF, FAG, etc) make this bearing size, so you're stuck using cheaper Enduro bearings. The DS bearing will last 10x as long as your NDS bearing (I'm not kidding), as water doesn't really channel to the DS bearings, and the crank arm blocks spray from hitting the bearing. Unfortunately, the NDS has none of those protections.

The only way I have found to minimize the amount of water ingress in the bearings is to routinely remove the crank arm and apply a good coating of marine grease (available at any boating supply store, like Outdoor World, as well as many auto parts stores). You want something that won't wash away if you get it wet, and many greases will. The procedure is simple: if it's only received a light spraying of water, you can make due with just putting grease on the dust cover. If, however, you go through something of a downpour, or have to really get after the bike with a hose, you are better off removing the crank arm, removing the seal and bearing, and then repacking the bearing with grease. To give it a really good cleaning, hit the bearing with some degreasing spray (WD-40 will work - you're just trying to clean all the gunk out), then let it dry and repack the bearing with grease, much like an automotive bearing is packed. Then replace the seals and reinstall the bearing. It does help to have a previously serviced bearing around, so you can just swap bearings without having to wait for the drying time, especially if you plan on riding the bike the following day.

One thing on bearing sizes: the BB90 bearing is a "slip fit" type bearing. It takes a little pressure to get in and out, and I recommend you get the Park Tool bearing extractor. As for installing the bearings, it's relatviely simple, and you can make your own press using threaded rod and washers. If the bearing slides into the hole with no difficulty, then you're going to need to get the "oversized" bearings, which are just slightly oversized. These bearings are a stop-gap measure by Trek to avoid having to warranty some of the bikes they were replacing. Now, if you have an oversized BB hole, Trek will just install a new liner and send the frame right back to you.

If you have any questions, just shoot me a PM. I do this work to my bikes (and my wife's bikes) all the time.

Ahhh this is looking all too familiar :) Very much looking forward to the finished product and how you will spec it out. That crank is darn light and I believe over 100 grams lighter than my set up! I think you'll love the bike, especially as it can make a pretty decent road bike as well, if you wanted to.

With respect to the BB, I have not had a single issue with mine. I am running a Kogel BB with cross seals and after around 1500 miles everything is still smooth and creak free. When installing things I did apply a bit extra thick waterproof grease to the area behind the chainring to give it an extra seal and generally try to keep the bike clean. Blasting that area with some compressed air after a wash definitley helps to prevent water from creaping in. I'm hitting close to 170lbs these days and have not had a single creak from the BB. My Trek shop has had good luck with using the semi-permanent locktite when installing bearings into BB90 and it's been nice and quiet.

ISO stuff is great too. One thing that I did discover is that you get far more comfort and smoothness when descending bad roads and gravel when you DON"T slam your stem and leave a spacer above the cone bearing cover. This allows the system to work better. Plus I enjoy the slightly more relaxed position as compared to my full on race bike.

Looking forwad to seeing more cming out of that kitchen ;)

Ha, it should! Your thread is actually what even sent me looking for a Boone! Now with the Easton crank out of the mix, it's going to look even more like yours. Oops.

It will definitely serve a fair bit of road duty - so I'm glad to hear that comment. I also took note of an earlier post of yours about not slamming the stem and actually sized down on the frame with this in mind. I'll be able to run a 10mm spacer (atop the giant cone) and not be CRAZY taller than my Tarmac. Still a bit higher, but as you said, the slightly more relaxed position may be nice. I tend to ride with a lot of bend in my arms anyway, so I can always just lean down :)

I've got almost everything ordered now, just need to wait for stuff to arrive. Unfortunately, I also head back on the road for work for most of the next month - so it seems like I'll have to practice my patience on this one!

Awesome! this should look good too and like the unique wheel choice. I think those 38c tires should fit fine but it might be close. I think I might be pushing it on my wheels since the internal width is 25mm and I'm already very close with the 36c Gravel Grinders. Should be a light build too! Any goals?

Ya I was also thinking that the seatmast looked a little short for someone with a 74ish cm saddle height. Maybe he knows something we don't :noidea:

Honestly no weight goal nor any clue where it will end up. I haven't even made a weights spreadsheet for this build! *gasp*

Sounds like you're pretty unfamiliar with Trek bikes. That's ok. The seat mast is not a complete part. Don't compare it to a standard seatpost. There is a topper that goes on there and is available in 2 sizes, short and long. The saddle goes on there. There should be no reason why this frame won't work unless he went down 3-4 sizes and had crazy long legs, which doesn't sound to be the case.

How tall are you? Just asking because my seat height center to top of seat is 75.5-76cm depending on seat and pedals and I run a 56cm boone. Personally I wouldnt size down for a cx or gravel bike especially if it will be doing a fair bit of road riding.

this is true, i made an assumption and i am sorry for that. i just measured lupina stack about ~~32mm from mid rail to top of saddle and power is a bit taller than that so it seems you may be fine, not sure on your saddle height though. if youre super anal, mtb cleats/shoes add stack but its nbd

Fat crank - but at least this one will fit -

Shoes and pedals also showed up today. Happily, my string of Bontrager and Specialized parts, coming in under advertised weights, continues:
