box four 8 speed shifterthe box four shifters main features arent strikingly different from box threes.
the key difference is its 8-speed platform.
weve chosen to modernize the 8-speed in much the same way we did the 9-speed for prime 9.
just like the prime 9, the box four shifters take advantage of the less is more theme and exploit durability, simplicity, and reliability.

all cogs are stamped from steel, given our durable black coating and then the larger cogs are pinned to each other with spacers for easy installation.

the chain is polished and then chemically treated to achieve corrosion resistance.
we engineered the inner link spacing to be a little tighter than other 8-speed chains and is optimized for use with our box four wide/narrow chainring.
