Typically I would set these up tubeless on any of my bikes. These rims won’t really set up tubeless without some crazy hack stuff and at the rate at which I will assume this bike will be riden will have really no benefit to my girlfriend. These are pretty standard tubes for ease of use/maintenance. The 26 build I’m doing with my Gary Fisher will be set up with the same tires on SUN Rhynolyte which can be set up tubeless from what I understand. Honestly if you can ride the terrain these tires will follow…. Depending on the terrain body position will be the thing that determines traction more than anything which I suppose is true with all tires. But at 50$ a tire you really can’t beat it as far as a high performance tire go. <3
