IWONDER Wheel Pulley Conversion kit PJ00608 3M-56T Cloud Wheel Discovery Version for Boosted Plus/Stealth/Mini S/Mini X Boards

I bought a 105 and 120 cloudwheel set from Exway to fit my Flex and Boosted Mini X not realizing that exway used a different pulley configuration. Ordered this set to get my wheels to work with my Boosted Mini X and had no problem. I suspect some of the negative reviews might not realize that the pulley wheel has to have the inside bearing removed as the pulley itself has a larger ID bearing for the axle. I myself forgot that and initially thought it wouldn't work, then I looked at the wheels I'd just removed, realized the inner bearing wasn't there and repeated on the cloud wheels and it was a perfect fit. No issues at all.

Fits great on my Boosted Board V2. If you find your cloud wheels stiffing up while you're tightening it and you're doing it correctly. Try adding a small washer either before or after the spacer. I recommend taking the spacer off, add the washer and then put the spacer back on. You should be able to tighten the wheel on with no issues while it spin freely. Everything will still line up perfectly. I'm still testing the quality of the belts. So, far so good.

I had to return this because it wasn't the right size, the teeth are tiny and well as the belt and the bearing for the gear is huge, make your this is the right one for your build

I bought this conversion kit for my Boosted board V2. I like the wheels, but one of the belts broke very quickly. I only used it for not even two months. I paid $50 for pullies and two belts for only about 10 miles of use. Not worth it.

This conversion kit didn't work and i wasted my time
