I am thinking to install Shimano BL-MT200 (or the BL-M315 depending on availability) on my son's bike (my son is 7 years old). The bike currently has short reach brake levers for the current mechanical brake set.
I want to make sure the lever reach is going to be OK. Shimano lists these brake levers as having "Reach Adjust", however neither the manual nor the dealer manual have any mention on how this is done. (which is unexpected because the Shimano dealer manuals are usually quite good)
How is the reach adjusted on these levers and is it likely the reach can be adjusted sufficiently for a child's hand?
