Absolutely! It's an IXF external bottom bracket / crank set combo, paired with a Snail 30t tooth narrow wide chainring, all available on Amazon. Super affordable. The conversion required a few specialty tools for removing the old hardware (square taper crank puller and internal bottom bracket removal tool) with one hollowtech wrench for installing the new bottom bracket.
There's a few good tutorials out there, just be mindful since you are working on the aluminum frame itself and stripped bottom bracket threads mean you'll need a new frame. I also took a few links out of the chain to help with chain slap and this thing is damn near silent now.
Tires are Bontrager XR4s, but they seem to have been discontinued in 29x2.3. They grip really nice off road but suck on the road due to high rolling resistance. Going to have to try something new once these wear out since anything wider might start scraping the frame.
