I know that there is a press embargo on this new Shimano item, but darnit, I'm a rule breaker and want to give all of you the inside line on this hot new item.
Injection molded polycarbonate body with indexed clicking action. Co-molded with an ergonomic rubber grip with a low durometer rating for great cornering. Light at only 13 grams! Black ink, that is supposedly made from crushed carbon fiber strands. 12 of the 20 UCI Pro Tour teams will be using this product and early prototypes were spotted in the Discovery Channel bus during the Tour.
Just remember, you saw it here first!
