SRAM TT Shifters

When SRAM was developing their new Red groupset, Design Integrity (DI) was brought on board to assist with the engineering design of a new set of time trial shifters. There are several engineering design services companies around Chicago and the Midwest, but SRAM saw how our team was differentiated by our ability to develop new products with a higher level of technical complexity.


Prior to 2007, SRAM established a strong position in the mountain and hybrid bike markets, but their new road component line was just beginning to gain a foothold in the category. Without a specialized shifter for time trial bikes, their new road package could not be utilized in three important stages in the Tour de France, which was just 11 months away.



The project started as a reverse engineering effort, but it transformed into a product improvement project as the team found ways to improve the feel, reliability, and cost. The first-ever carbon fiber lever was utilized to reduce overall weight. Special focus was given to the detents to meet the needs of riders, who require a solid and responsive feel from the shifting mechanism.


Client Benefit

The new TT shifters allowed SRAM to debut their road component package on time trial bikes in the 2007 Tour de France. The solid feel of the shifting action combined with the carbon technology drew “best in market” reviews from cycling magazines and demanding athletes.
