i get the name dura-ace (durable + ace?); ultegra sorta makes sense too (ultimate + alegra? latin something?).
what does 105 mean? it's such a step away from everything shimano calls its groups...
explain the Shimano 600 set then.
105 has been around for a while.
Since it's the middle road group, maybe they just left it to make it obvious? Nice stuff, not too pricey, not too flashy, good for commuting and just reliable in general.
So yeah..no idea. But I know its 'good enough' and easy to find if something does break...

Don't question. Just ride.
It's bad when you're 19 and people consider you an "old geezer" in the current FG community.
Why don't you call Shimano? Unless you're simply bored and want to start a pointless thread. If that's the case, then you've succeeded.
