I used this set to build a rocker plate for my Wahoo Kickr bike. The motion is still smooth after over 750 miles on it. Highly recommended for this use.
I bought this product thinking all the pzs were aluminum ,, on the picture #3 they show the bars as aluminum but they are steel ,, my mistake i didnt read the desctipti��n.. but if u guys can replace that picture.
I used this to build a dynamic rocker plate for a bike trainer. The rods were perfectly smooth without scratches and the bearings in the carriages are pretty good. The only reason it doesn't get 5 stars is because the packaging could use some extra padding and one of the carriage bearing seals was damaged rendering it useless. Thankfully I didn't need that particular carriage.
Not what I wanted but very well built. I'll find some use for them . Was going to make a router sled I think just ordered the wrong part I reorder the right one Shipping is fast I'll be using them again Thanks
