Review on SHIMANO Altus M311 system 175mm, 48/38/28T black by Danuta Stankiewicz ᠌

I installed 42-34-24 to replace the old system and the results simply amazed me! It is easier to spin the fat, the speed has increased by 1.5 times, it is easier to screw uphill, maintaining speed is no longer a problem. The only negative is overclocking. Acceleration is now not so fast and frisky. In summary, I am extremely satisfied with the purchase, despite numerous disputes on the Internet about large connecting rods and gear ratios. Set quickly, sat down and went. Went fast and easy!
