After suffering for a long time with slipping gears and inconsistent shifting, I finally plunked down the money to replace my drive train and it’s a beautiful thing. The shifting is silky. The gears stay where they’re supposed to be.
The new cogs are still the same: 50/34 compact double. The new chain is the same: Ultegra. The big difference is the cassette. I swapped out my old, grimy 12-27 for a shinny new 11-28. What does that mean exactly? Well now the highest gear is higher and lowest gear is lower so I will not only be able to climb with more comfort but also speed down descents faster. If I don’t hit 50 mph on Dublin Grade, I’ll be really pissed.
Is it the answer to all my problems? Probably not, but it’s helped tremendously. Now I just to need to take care of it to keep in good working shape for several thousand miles.
