Together with Trek, SRAM have developed the Boost standard for rear wheels, a standard that was first presented back in August 2014. Knowing that the advantages of a wider hub can work just as well as on the front wheel, SRAM subsequently expanded their product portfolio and this is now being presented. To give you as good an overview as possible, we’ve compiled all the Boost’s crucial information in a second article for you here.

SRAM XX1 and SRAM X1 cranks for Boost 148

As we already explained in the more in-depth article, given the new position of the chainline by the Boost hub it’s necessary to fit a compatible crankset. For this reason, SRAM’s offering a Boost-compatible XX1 and the X1 model, with prices standing at €493 for the XX1 and €284 for the X1 model. In the future there will also be a 3mm-offset spider, which will have the ability to upgrade former cranks to fit the Boost. Like the well-known 1×11 crankset, the Boost model also relies on the patented X-SYNC™ technology that maximizes chain control.

SRAM ROAM 40 Boost wheels

The Roam 40 is the first complete wheelset that SRAM have announced for Boost. For these wheels the axle/hub standard is 148x12mm at the rear and 110x15mm at the front. Like the small flange model, the Boost variant goes for lightweight aluminium rims, is tubeless ready and has SRAM’s Double Time™ hubs. The ROAM 40 for Boost is available in both a 27.5″ version as well as a 29″er.

Das Roam 40 29" Vorderrad ist für einen Preis von 342 € erhältlich, das Hinterrad kostet 397 €.
The Roam 40 29″ front wheel costs €342 and the back wheel costs 397 €.

SRAM X0 and MTH 700 Boost hubs

Even the well-known SRAM XO and MTH 700 hubs are available for the Boost technology with axle lengths of 148x12mm (rear) and 110x15mm (front). While the XO weighs 130g (front) and 250g (rear), the weight of the MTH 700 varies between 170-410g depending on the model. The hubs can take the XD driver body (11-speed) or a 10-speed one.

Der Preis der MTH 746 beläuft sich auf 85 € (VR) bzw. 124 € (HR).
Prices for MTH 746 start at 85 € (front) and 124 € (rear).
Die edle SRAM X0-Nabe geht für 206 € (VR) bzw. 380 € (HR) über den Ladentisch.

RockShox SID, Reba and Pike Boost – 27.5+ forks

SID, Reba und Pike sind bald nicht nur in einer Boost-Variante erhältlich, sie verfügen auch über neue Decals.
Soon the RockShox SID, Reba and Pike forks won’t just be Boost-compatible but they’ll have some nice new graphics.

RockShox have announced three Boost-compatible forks. As of June 2015, the SID (780 $ / 814 €) and Reba (620 $ / 647 €) models will be available in a 29″ version, which will also work with 27.5″ wheels. Come summer, the Boost-compatible Pike will be on the market for 27.5″ wheels as well as a 29″/27.5″+ option. All of the 110x15mm models are going to be compatible with the RockShox Torque Cap. This increases stiffness thanks to the larger surface area for the contact point between the hub and fork.

Die vergrößerte Auflagefläche des Torque Tube soll für eine größere Steifigkeit und so für mehr Lenkpräzession sorgen.
The larger contact point created by the Torque Tube should result in increased stiffness and guarantee better handling.
