Description
The Shimano Deore SL-M5100 shift lever is characterized by its simple and smooth-running operation so that the driver can concentrate solely on the trail ahead. Proven features such as Rapidfire Plus for shifting maximum 3 gears simultaneously and 2-Way-Release have of course been adopted by the right 11-speed shifter.
2-Way-Release
2-Way-Release allows cable release by pressing with the thumb or pulling with the index finger. So you don’t have to adapt your riding style to the rear derailleur, but the rear derailleur adapts to your riding style.
Content of delivery: right lever with optical gear display, incl. inner cable and casing
FITTING AND ADJUSTING TIPS

How to measure your foot length
- Stand with the heel to a wall and put a measuring tape under your feet
- Read off the measured foot length in millimeters before your longest toe
- If you are between two sizes, choose the next higher, because feet are minimally greater under load

Your feet should be able to move freely without your toes hitting the edge of the footbed.

Before trying them on, put one hand under the toe and one under the heel, then flex the footbed a few times. This will initiate the break in period and will your help your new sandals feel comfy sooner.
Open all straps and step into the footbed. Close the straps comfortably, leaving enough space to allow your feet the freedom of movement. Exhale and enjoy.
For the first five or six times you wear your new footwear, limit the time to just a few hours. This allows your feet and body to gradually get used to the contoured arch support as well as the straps and buckles.
