barcons set on friction let you PUT THE HAMMER DOWN. if you're as fit as your club buddies, you will drop them off the stops. like a block plus. friction lets you shift the whole cogset in one move, if you want. Great prepping for hills, and downhills as well.

I'll say it one more time: friction shifters lets you PUT THE HAMMER DOWN.

Barcons let you hold on, or palm shift, and fine tune while out on the drops too.
