Hi, i have an 2009 GT avalanche 2.0 SS converted and full rigid, i“would like to know if anyone have done this conversion...26 to 27.5, in the front i have an Pro carbon fork , so loads of space, my biggest doubts are in the back...it seems that it doesnt have much space...any kind of help and opinion is welcome.

Thank you in advance and greetings from Portugal.
