I've tried searching all the 27.5+ threads and Niner JET9 threads and I've found some good feedback on RIP9 and WFO9 with 27.5+ setups; however, I've found nothing about the JET9 frames and their ability to run 27.5+ sizes. To be more specific, I'm hoping to mount 27.5 Roval Traverse Fattie SLs (30mm ID) and I would like to know if anyone has had any success with 2.8 tires (Nobby Nics) on the JET9. I'm pretty sure the Fork will not be a problems, but I'm concerned about the frame. Any feedback would be appreciated. Thanks.
