The stock tire on a new Turbo Como 4.0 IGH is a Pathfinder Sport Reflect, 650Bx2.3 (front and rear). If I were to experience a flat tire while out riding, far from any local bike shop, what should I have with me in my trunk bag to at least help me get back home (let's say 20 miles away)? I understand that there is a range of variables here, front or rear tire, thorn or nail, and others, but I don't want to be caught without anything, so, what do you suggest I bring along? Thanks, in advance, for your thoughts, suggestions and/or experiences.
