Italian lightweight component manufacturer Carbon-Ti has added a new Centerlock disc option to their premium X-Hub SP family of straight pull CNC machined aluminum hubs. Developed mostly to build into lightweight disc brake road wheels, these are the first use of the centerlock interface for Carbon-Ti, adding more rotor compatibility, while keeping pricing unchanged & shedding some grams.
Carbon-Ti X-Hub SP lightweight centerlock disc road hubs
While Carbon-Ti already makes some superlight floating rotors down to 140mm for 6-bolt, many cyclists building up disc brake road bikes prefer to use the stock rotors designed for their groupsets. And since both Shimano & Campagnolo both make their premium 140mm & 160mm rotors only available in centerlock, Carbon-Ti thought why not machine their own option (using the rotor interface licensed from Shimano.)
Dedicated to road disc, gravel & cyclocross, the new X-Hub SP Center Lock hubs are only available in axle standards for road disc – 12x100mm up front & 12x142mm out back. Carbon-Ti says that the end weights are effectively the same as their 6-bolt version, so there is no real immediate push to add a 15mm front axle or Boost spacing option with centerlock.
SP means straight pull spokes, and both front & rear hubs are designed for 24spoke lacing.
The rear hubs use Carbon-Ti’s premium 56 point titanium engagement ring, grabbed by 4-pawls with three teeth each.
The X-Hub SP Center Lock rear hub is available with Shimano 10/11, Campagnolo 10/11/12, and SRAM XDR 12-speed freehub bodies.
Like the rest of the Carbon-Ti X-Hub SP family, theses new centerlock hubs are CNC machined in Italy from 7075-T6 aluminum, with variable thickness 7075 axles. The hubs spin on premium SKF bearings with adjustable bearing preload. Front hubs claim a weight of 89g (the same as 6-bolt), while the rear at 181g drops just a couple of grams off the 6-bolt hubs.
Pricing is unchanged at 220€ for a front hub, and 445€ for a rear hub, and the centerlock hubs are available in the same nine anodized color options at the rest of the X-Hubs.
