We have found Fairlane wheels to be very consistent like everyone else in the thread.
Only problem you could run into is they like to expand at higher rpms even the solid ones. To combat this we wrapped safety wire around the center of the wheel and then twisted it in turn locking it in place. This has worked very well and doesn’t effect the ball to dramatically.
We order the 11/4in ID wheels this season. And to get it adaptable to a 1/2in hex we took a short section of Vex Pro’s Aluminum Versa Roller and we center punched down the line in the on the tube this made it an almost press fit. As well as we used Red Loctite. After that we used the aluminum versa tube hubs and attached those to the roller.
In 2018 we used Fairlane wheels to intake the cube and they work well that year as well and had ally it grip. To attach them to hex this year tho we took 18t 35 chain sprocket and use loctite to attach those as well.
We’ve never had a problem with the hubs coming off. Through all 2017 season on our shooter and 2018 season on our intakes.
