The Ergon GR2 bar ends allow you to have additional hand positions on your flat handlebars. Perfect if you want to use your mtb or cross bike as a touring rig. The grips feature an easily adjustable angle of support that offers optimal pressure distribution on the palm to prevent soreness and numbness.
The difference in the sizing refers to the diameter of the grip. Size S is good for people with smaller hands as the smaller diameter allows a firmer hold. Size L is aimed at people with larger hands where a larger diameter provides more grip.
