First off - I'm not familiar with 27.5 size tires. This bike brings e-bikes as well as disc and the option for tubeless tires. I'd like to replace the bontrager tires eventually once those start wearing but want to start researching. I burn through 700c 19-23 in roughly a year and a half - including rotating. With commuting coming back up again in June for us in IL I'll be putting miles back on my bike. So what are our options for going tubeless for our allant 9.9s? If tubeless options are slim, what are other options besides replacing with the same bontrager tires when these wear out?
