Hey, Matt. The repair looks pretty hard core. And it will keep the crack from growing?? Interesting enough, I know that bike was only made in two sizes. 17" and 20". It looks like you have 17 and I know mine is a 20", but by the way it's designed the stand over clearance is more than my 13" kona hard tail. It's kinda like the bike is one frame piece away from being a full sus. woman's comfort bike. Compared to you and your son, me just a runt at 5-7, 145lbs, tho I do 3x a week at a cross fit style gym. It's helped my cycling tremendously, tho at 61 I still get my a$$ handed to me on the trails, haha. Like Mike mentioned in his post, don't think of a lot of Bianchi MTB's. Only one that always come to mind is the grizzly. I know zilch about their road bikes. Again, nice job on the collar repair and hope it holds up,as it looks like it will.
