How to Install TetraRack R2 on Road Bike Seatstays

Topeak TetraRack Series is a genius quick-mount rack system designed to easily adapt to fit full suspension rigs, e-bikes, mountain bikes, touring and road bikes – no eyelet mounts required. Special padded feet with adjustable straps cinch down tight to forks or seatstays and let you mount or remove in seconds.

Does it fit 4" tire? I have a Juiced Camp Scrambler.

Introduce a bag for the front rack. All my accessories in my bike are Topeak brand. I love them.

So for a 27.5 plus hardtail rear rack with 27.5x3 is the M2L the proper rack?
Thanks

I understand that this particular rack is designed to be installed in the rear. Was wondering if this could be converted or used in the front (reason I am asking is that a friend has a spare one and we barely have this brand here in our country)?
