NEXTIE ROLLINGSTAR II FRONT CENTERLOCK DISC HUB

Design and construction

The shell is machined aluminum on a hollow alloy axle with stainless steel cartridge bearings, sealed at both ends, and straight-pull flanges. Straight-pull spokes leave the flange in a line with no elbow, which lets Nextie cut the flanges light and lets us build a wheel with more even tension; it also means the lacing pattern is fixed by the flange geometry rather than chosen, which is one less thing to get wrong. End caps convert the same hub between 15 x 110 Boost or 12 x 100 front and 12 x 148 Boost or 12 x 142 rear, and the rotor mounts by centerlock.

This is the front hub, and a front hub has no freehub. What matters here is the part of the hub that carries the wheel: the bearings, the seals, the axle and the two flanges, and the front Rollingstar II shares all of them with its rear partner. It is the simpler half of the pair and the one that runs longest between services. The driver and engagement story belongs on the rear hub's page; this page is about a front wheel that spins freely, stays sealed and builds stiff.

How it rides

A Rollingstar II feels like a much more expensive hub. On a trail bike it is quick enough that you never think about a dead stroke; on a gravel or road bike it simply rolls. The straight-pull build gives the wheel a tidy, even feel under load that a J-bend wheel on a budget hub rarely matches.

It is not a boutique hub and it does not pretend to be: the finish is good rather than jewel-like and there is no lifetime warranty.

A front wheel is where you feel a hub least and a build most. With no drive torque to carry, the front Rollingstar II can be laced two-cross or even radial on the non-rotor side on a rim-brake bike, which makes a lighter, more direct-feeling wheel; on a disc bike we lace both sides crossed so the rotor's braking torque has spokes to pull against. Either way the front wheel is the one that steers, and a stiff, true front wheel is most of what makes a bike feel precise.

Specifications

This listing

This is the centerlock version: Thru Axle 15x110mm Boost, Thru Axle 12x100mm, 24h, 28h drilling, about 125g, in black, silver, red, gold. Same internals and flanges as every other Rollingstar II; only the mount and axle differ.

This is the centerlock Rollingstar II: the rotor sits on a spline and a lockring holds it, which saves weight over six bolts and makes swapping rotors a one-tool job. If your rotors are 6-bolt, a centerlock adapter fits them, or choose the 6-bolt version of the same hub.

Sizes, fit and compatibility

The Nextie Rollingstar II Front Centerlock Disc Hub is sold here only as a front and rear pair inside a complete Nextie wheel set. It comes in 24 and 28 hole with the axle options in the configurator: 15 x 110 Boost or 12 x 100 front, 12 x 148 Boost or 12 x 142 rear, centerlock rotor. Straight-pull spokes only; the configurator switches the spoke list to straight-pull the moment you pick it, and we build most Rollingstar II wheels with Sapim CX-Ray, Laser or Race straight-pull spokes and brass nipples.

It pairs naturally with every Nextie rim on the site, MTB, gravel and road, in any tier; choose the rim first and the configurator offers the matching hub pair and colors.

Build it with us

We build this hub to order. Open the Custom Wheel Program with the Nextie Rollingstar II Front Centerlock Disc Hub already selected and pick the parts around it; it is offered for gravel and road disc, touring, mountain bike and MTB single-speed builds, and the configurator will not let you assemble a combination we would not build.

Building it at ProWheelBuilder

Nextie designs and makes the Rollingstar II in Xiamen; ProWheelBuilder is an independent custom wheel builder in Georgia and not the manufacturer.

The configurator shows only Nextie rims and straight-pull spokes that fit the hub's drilling, strikes through combinations that are not made, and prices the whole wheel set live.
