Let us look at the pros and cons of the following sprocket:
11-34 MTB 10v
The 11-34 addresses a number of issues from 11 to 32. You can take a bike with heavy and have a short development metric that helps to overcome the difficult climbs.
Who is strong it can be used with bike 29er, having the ability to use 34 also climbs very hard (instead of 36); is great for the new bike 27.5er. A great sprocket for Mtb.
