I think there are two dimensions you need to work out - the jump between 36 and 60 (24 teeth) and the total capacity - (60-36)+(42-11) = 55. So to get this all to work properly you need a front...

I have seen a lot of unsafe behaviors on MUPs, sometimes resulting in dangerous situations and accidents. Riding no-hands doesn't really rank with some of the things I've seen.

189cm ~= 6'2"
