SEA OTTER CLASSIC 2010 에서 선보였다네요.
ISCG tab없이 쉽게 프레임에 장착할 수 있는 것이 장점.
Where HammerSchmidt relies on ISCG tabs to mount to the frame so it doesn’t rotate,
"the Metropolis PT" setup simply has a plastic arm that swings into the chainstay to prevent rotation of the entire unit.
It requires no frame mounts or modifications.
It’s a simple solution that opens up a lot of opportunity for people to install on existing frames.
In fact, FSA says installation is so easy,
an experienced mechanic (home or shop) could probably put one on and have it working in about 20 minutes.
FACTOID: The Patterson Drive is the brainchild of Sam Patterson,
who worked at SRAM for 14 years and helped develop the original Grip Shift products.
He doesn’t like "front derailleurs".
*You could argue that the Shimano’s 3×10 Dynasys or SRAM’s 2×10 X0 and X9 groups are gamechangers,
but in our opinion the 3×10 is an evolution, a good one,
and the 2×10 was all but foreseen for those two groups having already been announced on the X7 group.
