Veloci ROLLCii Rocker 1x Chainring

We’ve always liked simple drivetrains.
Less noise, less maintenance, fewer things to think about when riding.
That’s the idea behind the ROLLCii ROCKER BCD110 1X Chainring.

Fully CNC machined from a 7075-T6 aluminum plate, it removes unnecessary material while keeping the structure solid where it matters. The result is a chainring that feels light, direct, and stable under load.

The narrow-wide tooth profile uses alternating thick and thin teeth to improve chain retention and reduce chain drop on rough roads, gravel, and everyday mixed terrain. It also works with most modern 10 to 12-speed drivetrains, making setup straightforward without needing complicated adjustments.

The ROCKER is made for gravel bikes, all-road bikes, retro MTB builds, commuters, and bikes that simply get ridden a lot.
