Shimano 105 chainsets are known the world over for their reliability and performance. Having been refined from the previous version the 105 R7100 furthers this reputation. For this edition, Shimano have carefully engineered the R7100 crankset to offer an excellent balance between stiffness, strength, weight, as well as rotational performance. The result is a chainset equally suited to big days riding in the mountains, as it is fast bunch rides. Trickledown Performance Thanks to the benefit of trickle-down technology, the difference in quality between a 105 chainset and the more premium Dura-Ace or Ultegra versions is closer than ever. Now, with the addition of Di2 to the 105 R7150, the decision to purchase anything more expensive is even less justifiable. That is, of course, unless you simply want to spend the money on the flashiest tech around! All The Tech As with any product from the Japanese component giants, the FC-R7100 chainset employs some of the company’s top tech. Shimano’s famed Hollowglide technology means the outer chainring is hollow, to reduce weight but is engineered to do so without diminishing strength. This is the same technology employed on a number of the brand’s cranksets, including the top-tier models: Dura-Ace and Ultegra. Additionally, Hollowtech II technology is used to keep weight to a minimum, while maintaining strength and stiffness. The result is a crankset that won’t leave you bogged down on a climb and ensures maximum power transfer from your legs to forward motion. Again, this is the same technology employed in Shimano’s top-of-the-range models. Whether it’s the perfect chainset for big days out on the saddle or something for racing your local criterium the 105 R7100 is the perfect option, particularly for those slooking at a more affordable price range. It offers smooth shifting, an excellent balance between weight and stiffness, and won’t break the bank. Product Features: The Hollowglide structure reduces weight but maintains strength Crank Arm Lengths: 160, 165, 170, 172.5 and 175mm Gear Combination: 50-34T Q-factor: 148mm Weight: 765.6g (50T, 172.5)
