This is an excerpt of a review by Ride On for the ES complete bike built with SRAM Apex shifters and derailleurs, Sugino Alpina 50-34t cranks and Suzue wheels.
... It can be run very light, but I had it set up touring style with racks and mudguard. These accessories were no impediment to this feisty machine....Smooth speed is the natural expression of this bike... ES stands for "extra smooth" and derives from Soma Smoothie road bike...The smooth description however can only be relative to an out-and-out racing bike -- all day comfort on this machine is somewhat traded for thrills compared to the laid back randonneurs of this rider's experience.
A compact crankset with SRAM double-tap shifters ably provides for gears. The rear cassette changes down to a 32 cog which seemed ample to provide all the luggage with which one might handicap this fine steed...the IRD dual pivot calipers did not pull you up as effectively as your would expect. Fine tuning and some softer pads helped...
