Shimano 105

8 results

Shimano 105—or the ‘groupset of the people’ as it’s come to be affectionately known—is perhaps one of the most popular and widely used performance groupsets of all time. Designed with reliability and durability in mind, it still offers excellent shifting and overall performance. The release of R7150 brought, at long last, Di2 (electronic shifting) to highly coveted groupset. But, not to worry, the R7000 mechanicl series still benefits from the brand’s superior models through ‘trickle-down technology’. All this means, the gap between the brand’s top-three groupsets is now closer than ever, and with Shimano 105 you’re getting what represented the peak of technology only a few years prior.

High Tech, High Value

Across all its performance-range groupsets Shimano incorporates Hollowtech II technology into its cranksets. Using this technology, the brand is able to keep the weight of the 2x11-speed for R7000 or 2x12-speed for R7100 crankset down without compromising on strength and stiffness. The crankset is also offered in a variety of sizes, in terms of both crank arm and teeth size, so that regardless of your size and intended use you’ll find something that works for you.

Shifting gears is certain to be stable with the mechanical R7000’s Shadow rear derailleur. Available in both short and long cage options, add in an up to 34-teeth cassette and you’ll be able to tackle even the mightiest of climbs. 

The front derailleur has been enhanced, too. Gone is the in-cable barrel adjuster, replaced instead with an integrated cable tension port. This is something introduced to Dura-Ace and Ultegra level models, which results in lighter shifting between the front chain rings.

At the controls is an ergonomically designed shifter, which for the latest edition has received similar treatment to the pricier Ultegra R8000 series. Overall, the shifters have been reduced in size, and re-shaped to make them easier to grip in slippery conditions.
