As I said, mtn hubs at 135 will be more common than road disk hubs at 130.
I'd still be tempted to go with a 50/34 crank, but if you rarely find yourself in the three lowest gears on your mtn bike, then it's a wash, stick with the bigger crank. With the Rival groupset, you could always swap out to a mtn RD (X9) and 11-36 cass if you find you miss the lower gears.
i ran the compact crank numbers, and you only loose .6 mph @ 40rpm
but get closer to what a mountain bike does.
so going to stick with one of the 11-sommat cranks, and i'll recheck the numbers later. Just so I can go as fast as I can.
The sprocket jumps on the cassette quite reasonable.
Decided to go with Hope Pro 2 EVO hubs with steel freehub, in silver.
Stainless spokes and hub silver with black nipples and rim.
