Trek has created the Soho to marry the speed that is possible with road bikes to get to your destination in a timely manner, with the maneuverability that a mountain bike offers to dodge the obstacles of the city. As a result the speed and maneuverability doesn't match up with bikes that are created for that particular category, however in unpredictable environments such as a big city, flexibility is paramount.
The frame is manufactured out of Trek's Alpha Aluminum compound which mixes durability with light weight processes, again a compromise for flexibility. The stock tires are Bontrager Race Lite Hardcase which are puncture resistent and made to withstand significant wear and tear.
A 9-speed transmission is standard but can be replaced after market. Commuting bells and whistles come in the form of a custom built coffee thermos and corresponding holder, as well as a rubber protector on the top tube to facilitate leaning the bike against surfaces such as light poles. To handle a variety of wet and dry biking conditions, disc brakes are used which retain consistent stopping power no matter the weather or terrain.
