We also identified a couple patterns of non-change:
Unchanged front ends
Since Giant started the movement to front-end integration with the Trinity Advanced SL, there has been a major improvement or change every year—until now. Trek set the bar for total integration while others, including Cervélo and Specialized, pushed to balance aerodynamics and functionality. This year, the new tri bikes on display borrowed strategies from existing bikes.
Last spring, Sram teased upcoming hydraulic disc brakes designed for road bikes. If you’ve ever jumped on a mountain bike with a similar set of brakes, you know just how much of an improvement they can be over caliper brakes. Well, it turns out that managing the heat created on a long descent creates problems, so neither Sram nor Shimano has a set ready for the public just yet.
