There was a posting I was trying to agree with when I noticed it was removed, probably because of word choice. Overall, though, I agree in a more PC way.

When a 7-year old has problems with a new bike most people wouldn't consider it related to his weakness. It's probably the fault of the store for failing to identify an issue (grip shifter strength) that happens regularly on kids bikes or the parent for failing to make certain the child could operate the bike before he left the store.

In my opinion, only weaklings blame their problems on 7-year olds.

BTW, I agree with wrk101. Go with trigger shifters like many 7-year olds use.
