BB30 Bottom Bracket upgrade options

Hey everyone...new to the forum...and semi new to gravel riding. 

I got a great deal on a 2015 Specialized Diverge Expert a few weeks back after being on the lookout for a gravel bike for like 3 years now. 

I live at 11,000 feet in Colorado and wanted to go light etc with the bike but never had the money. 

Bike was a "blem" model that my local shop got me. Honestly it is basically brand new. Not sure why it was labelled a blem...could have just been tested and then they could not sell it "new". 

Anyway. I have developed some noise coming out of the bottom bracket now after about 100 miles of riding. I am pushing the bike hard and treat it more like a MTB than a road bike. Gravel riding where I am is not the same as elsewhere in the country. 

What are some options for BB upgrades or something that will be more robust and not start creeking on me every 50 miles after a re-lube? Has the BB30. 

Thanks! Hope to contribute here more. 

Thanks! 

I am in discussion with my bike mechanic about what to do. 

I may just leave it until it gets really bad. 

It was popping and making noise and then the last ride I went on it was silent. 

So ya no clue. No clue how you get a 4000$ bike and they cheap out on some of the parts. I mean if someone is considering dropping 4k they would not mind 4500 if some of the parts like that were better. I know companies have price points but come on. 

Do you know if the BB30 style BB can be modified to take a different type of BB if I ever wanted to switch out and go for smaller MTB style chain rings in the front? I already put a 11-40 cassette in the back and might go bigger. I ride up above 12k feet regularly and we have some steep steep ass climbs out here. The force of cranking a 40 toother in the back sitting down is still to much sometimes and I get rear wheel spin. If I could pedal with less force it might help keep some traction when crawling up some of these tracks out here.

@NoCoGreg

I got a bottom bracket that I am going to have my local mechanic install for me. 

The BB issues seem to resolve themselves in warmer weather I would imagine from pieces parts expanding slightly eliminating the creaking. 

As far as the cassette and chainring etc. I am doing fairly well with the 40 I have. I think it just came down to learning to pedal at a slower cadence, settling in on a rhythm I can sustain and then working to keep my heart rate and overall effort in check. Basically just getting stronger overall. So far so good. 

If I can get used to the setup I have now (I think 50-34 in the front) which shouldn't be an issue it will suit me better on flat roads if I am ever out with the roadie friends.
