Just picked up this 2021 Sirrus X 5.0 in XS, with 165mm Praxis Alba cranks and tubeless tires.
Coming from narrow tire road bikes and older hybrids, this one feels like it was designed in a different universe. The ride is silky-smooth in comparison.
Upgraded the saddle/post to an FSA CarbonPro post and a Selle Italia Kevlar Flite saddle.
Next upgrade would be a 660mm carbon handlebar to replace the original alloy.
So far, so good. This bike really works for me - light, agile, smooth ride, wide gearing.
