I’ve started to get into endurance type riding. I was doing 50+ mile rides on the hybrid bike, but it was time to graduate to a road bike. I bought a new Trek Domane SL8 road bike that has carbon with more carbon and a full Shimano Dura-ace group set. It came with a compact crank (50/34) paired with a 30-11T cassette. Since I am doing some events with 7000+ feet of climbing, I wanted to be able to “call granny” to save my ass when my legs turn to rubber. The largest Dura-ace rear cassette is 30-11T, but you can swap in a Shimano Ultegra R8000 32-11T cassette without any problems. I didn’t have to lengthen the chain or do any other trickery such as using a Roadlink by Wolf Tooth.. The image above shows that the derailleur is not hitting the cassette even when in “big-big.”
