I think it is great.
It is a group of hard working, dedicated girls(looks like tri girls) who are proud of being strong.
Think about it, we have had plenty of threads on here about CHICKing a guy. This is what it is.
I love going out on the fast group rides and giving it my all(26-32mph rides). I love even more, hearing after the ride, how strong I am from the guys.
A lot of guys can drop me, especially when the pace gets over 30mph(if it is a sudden jump to that pace, my acceleration sucks. but I can gradually get there and maintain it in a pelaton just fine).
But I know I can drop a bunch of guys out there also, I have the endurance to work in a paceline in the mid to high 20s and I love knowing that I can drop some guys.

So yes, these kits might not be for everyone- but for the hard working girls who put time in and are just as strong if not stronger then some of the guys out there- it is great!
