Wheel Tip!
When you add new wheels to your board it is also the right moment to get new bearings. Bearings make sure your wheels keep spinning and give you a smooth ride.

Sector 9 Nineballs 70mm 78A Clear Purple Wheels | set of 4 - Key Questions Answered
What kind of riding are these wheels best for?
They’re best for cruising, commuting, and relaxed carving on rough city pavement. The 70mm size and 78A urethane help smooth cracks and chatter without feeling overly bulky.
Are these a good choice for a newer rider?
Yes, especially if you want more grip and stability while learning to link turns. The soft 78A feel is more confidence-building than a harder, slide-focused wheel.
How do they feel compared with smaller or harder wheels?
They roll smoother and quieter than smaller, harder wheels, with more comfort on broken pavement. You give up some snap and slide freedom, but gain a steadier ride for everyday use.
Will 70mm be too big for regular pushing and commuting?
For most riders, 70mm is a sweet spot: fast enough to carry speed, but still manageable to push. It’s a practical size if you want comfort without moving up to 75mm or 80mm.
What should I expect from the clear purple 78A formula on rough streets?
Expect a softer, grippier ride that tracks well through turns and helps cut down foot fatigue. The clear purple urethane is tuned more for comfort and control than aggressive sliding.

Skater since 1974, pool pipe and skatepark, I've ridden it all but these Carver C7 trucks were a revelation. Best for slow speed styling and generally hanging some art on mellow terrain.
Definitely a kick and worth trying.

I am loving this board so far! I reached out to LBUSA to get some help finding the right board for me. They were more than helpful and the process of getting help, ordering the board, and then delivery was flawless. I am excited with my purchase and am thrilled with the customer service along the way. Top notch!

Well built and super fun to skate on. Wheels work well on imperfect pavement and sidewalk cracks. Bearings are legit.

Kiddo got this board for Christmas, for us to ride on Route 66. Board is good quality. No name trucks, but they function well for her. She likes the Punked Speed Series wheels. We did put reds super bearings in it. The factory bearings do not roll near as well. For the price, for a complete, it is well worth it. This is our second Punked Longboard, and both have served their purpose. I would buy from this company, and Vendor again, without question.

Trippy assym setup with Rogue ZM1's and assorted wheels really rips for downhill! I also hope to run cones with it soon.
