Look into Wickwerks chainrings. They make 46/34 and 44/34 chainring combos for SRAM cranks

I went with the OX601D from Hubjub. It was pricey at ~$250 but was best option to lower the gearing on the front while still allowing me to use brifters...
). However, I wish they made more 14-x cassettes. On my 3x6 speed old MTB, 14-28, and 14-32 cassettes are widely available and cheap. That way I use all the available gears, don't need to cross chain much from the big ring, and the chain and sprockets last longer. For drivetrain efficiency and durability, it's always better to ride higher total number of chainring teeth - 52-17 being more efficient and longer wearing than 42-14. However, with modern 11-x cassettes, the 52-17 is so cross chained, that it makes no sense to use it over another option.

You might consider 1x if you don't use/need the higher gears. I love not having to deal with the FD. The Rival 1x RD and X-Sync chainring will run about $140. The smallest front SRAM chainring is 38t which would give you the 25 mph top speed you want, but you'd lose a little on the lowest gear with the 38x32. If you're willing to replace your cassette, then you could go with a 11-36 and maybe even 11-42.
I swapped out the front chainring to 44t and very happy. With 11-36 out back I think it has nice range and spacing for me. Heck I still don't use the 44 x 11 gear combo.
