The Trek 2.3 is the next step up from the 2.1, maintaining the same frame composition and similar geometry but with an upgraded drivetrain. Other updates include Bontrager Race wheels and Race Blade handlebars, and a switch from Shimano Tiagra to Shimano 105 breaks. The crank has been changed to a Shimano 105 from the R-600, but other Shimano components are the same including the shifters, derailleurs and cassette. The grade of metal used for the frame is part what sets each series apart and this one uses the middle grade Alpha Black Aluminum which has been hydroformed for some aerodynamics. The SpeedTrap compatible fork has a port that will accept special wireless transmitters(sold separately) that can send speed, cadence and distance data to any ANT+ capable device such as a GPS receiver. WSD version is only available with the 2.1.
