Why would the bike care if it's 1/4" or 3/4"? It's not like you can't get an adapter to take them down to 1/2" or even 3/8" if you are so tempted. And since the ratchet and breaker is included, why not use them? And who says they are only going to be used on an RE? When you got to that 47mm sprocket nut, you might be glad you have something that's almost big enough to break it loose. I used my fork tube extension to got my sprocket nut off! At least, I asn't worried about breaking a tool.
I've found the set pretty handy, actually.
