I have my 780mm bars in a 130mm stem on one of my bikes. Fun ride, but would probably feel weird if you're more used to Trail or All-mountain bikes. If you're used to XC bikes then it would just feel really wide
This bike has a 56cm ETT. On my bike with 60cm ETT I'd probably pair it an 80mm or so, since that bike also has a setback seatpost.
