Hello! Thanks for commenting! Yes you can use regular shoes and they are a big improvement grip wise. I recommend thicker and harder soles. For example if you use a pair of Converse, you are going to feel every single pin. For the plug and play thing. They are universal. Just take note that the left pedal screws counter clockwise. About oiling the bearings comes sealed with grease so you don't have to do anything in the short/mid term.
They are very long indeed, I think it is better to find aftermarket pins, the head space is so narrow that I don't believe there are washers that small available. But to be honest I got used to them.
I've had this before, it is extremely aggrasive. It's perfect for commuting. This pedal are designed for gravel and MB that means it assume your shoes already covered in mud. These pins are just too long for commuting, i would like to switch them to shorter pins (very easy to get at anywhere). GR400 is such an unOrthodox pedal by Shimano, never think they had ever made such things before.
Hello! Yes they are very aggressive. They ate through the sole of my regular sneakers. After I bought dedicated MTB things changed completely, the grip and stability is impressive.
@@YuichiTamaki And GR400 is very complcated to my mind, i cannot tell i hate or love it. It almost has the smallest stack hight so it really rides amazing. Also the build quality is perfect. It's especially good for short to medium route of commuting. And when wet much better even. But i tried to ride it 200km within 2 days, I can say I can feel the DU bearing ate some of my watts.
@@mohongzhi That's an interesting experience, I've never thought about the bearing drag. Could you tell me what other pedal did you try with less drag feeling? Thanks a lot!
@@YuichiTamaki Most of mine pedals are pure bearing system, MKS, Shimano 202, T8000, are all lose ball bearing, and my look clipless are needle bearing. Others are sealed bearing. Ball bearings are just too smooth and you cannot feel any drag. But any kind of pedal in full bearing mush have a much higher stack hight. Pedals with plastic DU bearing can make extremely low stack hight pedal, and i think GR400 really goes extreme in this way. It seems the smallest stack hight pedal on market. You can feel the difference, that make your feet on GR400 feels so direct mounted on bike. Anyone tried GR400 will say it's so connected and grab so tight. I think this feeling much comes together with these long pins and extreme low stack hight. Higher stack leads to more chance to flip the pedal, thus although i don't wish to feel and DU drag but I still missing the feel of extreme thin pedals. I think I will get mine GR400 back and put it on my commute bike and try not to use it on more than 50k rides. Haha... Cheers. Oh maybe I should try these with one DU on the crank side and one very small sealed bearing on the other side. Those are not as thin as GR400 but much thinner than any pedal with two loss ball or sealed ball bearings.
Hello! thanks for commenting. Yes you can remove the pins. What I am not sure about is if you can find shorter ones. In my quick research I only found the original replacements. Maybe aftermarket?
Can i use normal shoes and are pedals plug and play no need for oiling in bearing thanks

This pedal is in DU bearing so no need to maintain at all until the DU bearing wear out and that will be more years away than you can think of it.
Nice, but these pins look too long, I think it might work to put small washers on the screw head side.
