Each one of my rollers need two wheels of 76 mm for the front, two of 80 mm for the back.
I'm not sure if I have a good technic, but my two front roads are wearing out more quickly than the two others of the back.
Since approximately six months, I bought four wheels of 76 mm to be prepared to change the two front wheels of each roller.
Today, I thought : why not change all my wheels? They are no longer usable! So, I bought four other wheels of 80 mm (for the back).
After changing all the wheels, I decided to measure out the old ones. These from the front are more than 10 mm less, but... these from the back are just around 75 mm. Why not use them for the front?
The four wheels I bought six months ago will wait some more!
