EZ Knees made of aluminium. Pretty good quality. it will add inches to your fender saddle. The only issue was that it is noisy because my stirrups is made of aluminium and the EZ Knees is made of aluminium as well so the friction creates the noisy, so I decided to wrap the stirrups around with some cotton tape around and the noise improve a lot. however I do not know how it will hold the tape around the stirrup.
