Felt Bicycles IA Advanced Ultegra Di2 - 2020
Details
We can tell you that the IA is the most aerodynamic bike in the world. We can also say that it’s the best-handling triathlon bike on the planet. But what we should really mention is that the IA has won the Kona World Championship a staggering six times in a row, and it’s set both new bike course and overall course records across the lava fields of Hawaii. So, really, what else do you need to know?
Buy it if:
You want the winningest bike in triathlon, one that emphasizes aerodynamic efficiency, ride quality, and real-world usability, all in equal measure.
- The most aerodynamic bike in Felt’s history w/endless fit adjustability
- Shimano Ultegra Di2 drivetrain
- Reynolds AR58/62 DB Custom carbon wheelset
- IA CALpac 2.0 and IA BTSpac storage boxes
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Shifting Performance
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Customization
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Dependability
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
