Is there a way to build a 1x bike (TRI) for a area that has quiet a bit of climbing?

Of course, it just depends what ratios you want. You can get a huge spread but if you are not used to it, the jumps between gears will be noticeable.

What would be the maximum grade you might expect to encounter? What are the maximum speeds you reach on the downhills, and what gearing do you ride now. I really like 1x, but at some point you might be better off sticking to 2x because front chainring size is kinda limiting until they come out with 10 tooth cassettes.

Build:
Shimano Di2 Shifters
XTR/XT Di2 RD
Sram 10x42, Shimano 11-40, or go crazy with OneUp 11x50 cassette.
46 or 48 chainring

you have to figure out how many gear inches you need to get over the harder climbs. Say now you can ride your hills in a 39x25 gear, which is 41 inches. If you went with a single 48 in front and put a 32 in the back, you'd be a 39.4

On the other side of the coin, your current 53x11 gives you 34 mph at 90 rpm, switching to the 48 would lose you a couple mph before you spun out

I use this calculator to figure this stuff out
