The long-awaited Shimano 105 12-speed mechanical has arrived

It has been long awaited, especially when a year ago the Shimano 105 Di2 was presented. The Japanese brand could not let down the thousands of cyclists who have always trusted this groupset as the best value for money option for a fully functional bike, even for intensive use, with a performance very close to that of the top models but at an affordable price.

Shimano does not forget about mechanical gears with its new 105 12-sprocket gearbox

Reliable components, easy maintenance and, above all, an affordable price. These are the mantras of the cyclotourist groupset par excellence that continue to be maintained in the eagerly awaited 12-speed mechanical version of the Shimano 105 groupset, which expands the options in the medium range after last year's launch of the Di2 version of this groupset.

It was already foreseen a few weeks ago that the launch of this groupset was imminent when Bianchi began to announce on its website some setups of the 2024 range among which reference was made to this new groupset. Now it is a reality that continues to maintain the excellent performance to which we were accustomed Shimano when it still maintained mechanical groupsets in its top of the range.

Oriented as it is to the touring cyclist, one of the key elements of this new Shimano 105 is its very affordable gearing to make it possible for a greater number of cyclists to tackle any type of route regardless of the ramps they are going to find on their way.

It has two crankset options, 52/36 and 50/34, which are accompanied by 11-34 and 11-36 cassettes, developments more than enough so that we do not resist those slopes where the clinometer rises above the double digit.

Inheriting features from Ultegra and Dura-Ace, it is worth noting the redesign of the disc brake system to allow greater separation between disc and pad to avoid the annoying friction that happens on many occasions when we stand on the pedals. It should be noted that, following the market trend, this new Shimano 105 will only be available for hydraulic disc brakes, taking a further step in the banishment of the traditional brake bridges to the rim.
