Good evening ladies and gentlemen! Tonight, the much anticipated match-up between Shimano brothers.
On the left, Ultegra, weighing in at 242 grams with a reach of 11-28 and on the right, it's weightier brother, weighing in a whopping 329 grams and an amazing reach of 12-30 is Tiagra.
In this contest we'll see just how much that 87 gram (3.06883469 ounces for you Americans) matters on a bicycle. Though Tiagra surely weighs more, there's the matter of teeth to take into consideration. That 12 tooth vs 13 tooth high end likely won't matter with a 52 tooth chain wheel, so we'll call that a draw for now. But on the low end, where the real contest will take place, that 30 vs 28 may make all the difference when the hills hit 12 and 15 percent.
Is it better to be low, or light? How much will that 3 ounces matter, or, put another way, will 24.5 vs 26.25 gear-inches make up for that 3 ounces? Both combatants will be paired with a 52-39-30 support staff and a long-cage derailer in their corners. Settling this contest is why we meet here tonight.
This fight promises to be a rough one, with trash talk even appearing on the Tiagra Box, placed there no doubt by Ultegra fans. Since both lads are looking at double centuries, Tiagra faithful ask "How can Ultegra characterize Tiagra in such a dismissive manner? It's just BS coming from a lighter sibling" Ultegra fans just continued their chant "Fat! Fat! Fat!"
We'll be back right after a word from our sponsors with tonight's featured match, and find out what Sierra Road near San Jose has to say.
