Отзыв о Rear derailleur Shimano Deore RD-M4120 10/11 speed. SGS black от Gloria Constanta ᠌

Before buying, you need to know exactly what _ what_ you are buying it for yourself, namely which cette. Now the Deore series is inflated by 4000, 5000, 6000 - each of them has its own number of stars in front, its maximum large rear star in terms of the number of teeth, its own number of transmission speeds. For correct accurate work, everything must converge in one place :) The index is "20" for two stars in the front, although with such a range of stars in the back I decided to simply leave the second star from the clic Deore system for 32 teeth in front and so far the chain does not fly off even without a damper. So the tension of the chain so far (skated 150 km since the beginning of the season) is holding!
