If you have a spurcycle bell, you can buy this bar end mount for the bell...

$30 for the black version, and $39.56 once tax and shipping are added.
It's more expensive overall than the canyon option, but lower shipping, if that's really what bugs ya!
I think the only real value is if you already have a spurcycle, since it would allow you to keep using that bell and they are nice bells.
