Coming in even lighter than their SL hubs, the new Carbon-Ti X-Hub SP (for Straight Pull) expand the range to cover all XC to all-mountain axle standards…including newcomers like RS-1 forks and Boost.
Same internals as the original SL models that use J-bend spoke flanges, but it’s much more machined, taking 3x as long to make as the SL to manufacture the shell. Shell material is 7075-T6 alloy rolling on ABEC5 sealed bearings and they’re 100% made in Italy.
Check the weights and more below…
Retail for the hubset will be about €650 (VAT included). In the U.S., get ’em through Fair Wheel Bikes, price TBD.
The SP hubs keep their clever (and very easy to use) knurled bearing preload adjuster. Just turn it as indicated to change the preload.
The RS-1 option should be one of the lightest hubs for Rockshox’s inverted fork.
The X-Hub SP Road brings disc brake compatibility to the pavement, too. All options and weights are:
- Road: 95g front / 185g rear
- MTB QR15 front: 91g
- MTB 12×142 rear w/ XD driver: 185g
- RS-1 front: 112g
- Boost 110 front: 95g
- Boost 148 rear w/ XD driver: 188g
Their X-Rotor SteelCarbon 2 disc brake rotors with carbon carriers now come in a 180mm size, too. Weight is just 94g, and it joins the 160mm (78g) and 140mm (65g).
Their O-SyncroCam multi-ovalized chainrings mimic Osymmetric’s shapes, but in titanium, which they say lasts 3x longer than alloy chainrings.
Those will get new sizes and, along with upcoming 96BCD for current generation Shimano XTR chainrings, use their minimalist narrow/wide tooth pattern.
