I don't know how many shift I did since I start my riding period.After so many years my bike shifter rubber cover was cracked & needed to be replaced.This OEM shift pedal rubber cover looks heavyduty and strong.This rubber cover will protect my left boot from damaging when I shifting gears.Installation Process is very easy .Apply waterproof grease to the rubber cover contact area then slowly push it until the rubber cover goes into the shifter lever.this small rubber cover makes a difference! Not sure how much it protects boots but most importantly it protects my foot by distributing the pressure much more evenly.It seems well made but thick. It's also soft rubber.After Installed I went for a ride . I really didn't notice any difference in the position of my shift lever and how I shifted. It's slightly noticeable because of the thickness, but the shift cover is so soft that it really didn't interfere nor change in the way it felt. I actually forgot I had it on.That's when I realized that it works pretty good. SO I given it a 5 star.great value for your money as it is cheap, but not in quality, the price is low but it gives exactly what you need..Thank You WEBIKE!!!
