Introducing the NOVAs, beautifully crafted 68T all-metal pulleys using aerospace-grade 7075-T6 aluminum. Claim back your acceleration and braking power! Pair the NOVAs with the new Boosted 105s for the ultimate upgrade!

  • Superior Durability and Reliability: The high-performance grade aluminum of the ATOMs results in extreme resistance to stress and damage. Say goodbye to chipped pulley teeth and hello to extended belt lifespan. 
  • 68 Tooth Count: The NOVAs give stock gear ratio performance in terms of acceleration and braking power when paired with larger wheels, all while gaining the top end speed and comfort of larger wheels. No more compromises.
  • Unmatched Strength-to-Weight Ratio: The NOVAs offer an unrivaled blend of strength and performance. 7075-T6 is truly in a class of its own, offering over 2X the tensile strength and 1.5X the shear strength of the common 6061 aluminum. The T6 temper treatment is the icing on the cake, yielding the peak strength of 7075 alloy. Without a doubt, the NOVAs are THE strongest aluminum pulleys on the market. 
  • Solid Piece Design: The NOVAs are CNC machined from a single block of 7075-T6 aluminum, resulting in uncompromising structural integrity. No need to worry about screws coming loose!
  • Precisely Engineered: All interfacing aspects of the NOVAs are precisely measured and machined to ensure proper fits between components, such as our renown ROMP belts, wheel hubs, and stock pulley bearings. No slop here.
  • Minimized Rotational Weight: The hallowed-out design coupled with the the 7075-T6 aluminum results in the lowest rotational mass for metal pulleys. In terms of performance, lower rotational weight means faster acceleration and braking. 
  • Beautifully Finished: The NOVAs are bead-blasted and anodized to provide additional resistance to wear and corrosion. So beautiful, you'll want to display them on your mantle!


The NOVAs are designed to fit the Gen2 and Gen3 Boosted Boards only and pair perfectly with Boosted 105s or other 100mm wheels! This translates to the same stock acceleration/torque and braking while keeping the higher top end speed of larger wheels. 

The NOVAs do not require the use of retaining compound or "glue" to secure the pulley bearing in place. However, we still recommend using Loctite retaining compound to ensure the best fit and eliminate unwanted noise and wear on the inner barrel surface.

A must-have upgrade for larger wheels!

This is a very necessary upgrade with larger wheels - acceleration is restored, braking is restored, and motor life is restored.
These are the best quality pulleys on the market and Romp's customer service is great!

Max Krisch Svärdby
Solid, but not 110%

Love the product, great addition for longevity and speed. But they don't my 105's perfectly which is not great. The wheels can be pushed sideways on the axle whilst being fully attached. But I've been riding like that for two seasons now and it still works out.

The torque is back!

I recently purchased some Onsra 115mm wheels and was struggling to get uphill with stock Boosted pulleys. With the Nova pulleys the torque is noticeably better. Product quality is very good, 10/10 would recommend

Not perfect.

+ Acceleration and breaking power is back
+ Aluminum Pulleys
- Expensive
- Heavy
- New motorcaps out of plastic

J Enberg
Super NOVAs

They have a great feel an quality I have not seen anywhere. Downside... It will be nice to have a belt guard big enough to cover.
