The wheel has a strong brushed finish alloy hub which is made from 1 piece lathed aluminium. The rubber appears to be of excellent quality and has an increasing resistance when compressed as it has a foam insert for cuishioning.
These are an excellent looking wheel and will last long enough for you to pass them on to your grandchildren.
Excellent quality and a solid light weight design.
If you need these order JUST THE WHEELS. They will be on back order and you will be in line for them when the new stock comes in. I had 4 sets on back order for a little over a month. The larger sets have the longest wait.
I have bought a pair of these in the past. If you look at the corner of the picture you'll see a set of plastic bushings which give you a selection of sizes. I don't remember what all sizes are included though.
I have just chatted to live support and they have told me that the email i received saying they are a pair is wrong, they are sold single. Still waiting for 3 months for these to arrive. Having second thought HC!
I ordered 3.75" wheels, but received 3.5". Anyway, before sending back, I measured 2 most important thing that neither UH or many customers did not provide. The weight of the wheel is 56 g, and the width is 32 mm. Plastic bushings allow to use shafts of 3, 4 and 5 mm diameter. And no, those wheels do not come in pairs!
