Go to Post There is almost always more than one solution to any engineering problem. One part of elegant design is picking the one that makes the most sense for a particular design problem, even if that means "breaking" some normally established "rules". - Jeff Pahl [more]

This certainly looks like a great solution... but it's a solution to a problem we haven't seen. Is it common for teams to sheer bolts in this setup?
1618 in 2007 had this issue; after one good hard match we had five of the six bolts sheared off in our re-skinned kit wheels. The time of repair meant we had to send a human player to our next match (we lost it).

However, one incident in seven seasons of this style of bolt pattern is pretty respectable in my opinion.
