I’m impressed with the ultraspin on these, I’ve never had them before till now. The 61d duro is crazy. It’s So realistic and very grippy literally looks and feels like a real wheel I think softest duro I’ve tried. The bearings are much louder on the 61d wheels than the bearings on the 71ds. Yet both are very nice feeling. Comes in handy when you want less friction reverting your tricks and powersliding and skating rough terrain.
The 71d wheels are a tiny bit smaller maybe by 0.2 “7.5” the 61d’s being “7.7mm” I believe. Awesome wheels!
