    It will force you to keep a higher air pressure in the rear tire so you don’t rub once loaded and hitting bumps. You could also lean it forward a bit and try to get the high point of the tire between those crossbars.

  2. ISO standard, which is good starting point, states 6mm clearance between inflated tire and frame on an off road bike. You might be a bit close.

    Op- have you measured the clearance?

    Is the tire new? Is the pressure at your normal or even a bit higher?

    It’s almost like those tire saver things we used to install back in the 80s which would scrape off thorns and such in helping to prevent flats… so retro!

  5. I’d ride it, but I’d be concerned about future tyre replacements. If that doesn’t matter to you then go have fun!

    (Btw, I believe it’s generally pretty easy to extend where it attaches down at the bottom to give more clearance, but I can’t find a link right now, hopefully someone else can!)

  6. If you can modify or exchange it I would. If not it is likely ok for dry conditions, especially if you swap for lower profile tires.
