The Red Metal XRP 650B is a tubeless wheelset ready for the rigors and extreme demands of professional racing.

Light enough for the toughest of climbs as well as the quickest accelerations on race day, the Red Metal XRP 650B wheels ooze performance second to none.

Helping to keep rotational mass at a low, the rear wheel boasts a milled rim and lightweight aluminium nipples. Double seal construction, with one seal directly incorporated into bearings and another in the hub, ensures that these wheels maintain their efficiency over time and can stand up to the most demanding terrains of off road cycling!
Technologies

2:1 Two-to-One - When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension.

F.I.C. Fulcrum Identification Card - 100% Handmade Quality Right from its inception Fulcrum has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”.

Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company.

Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum® makes every day to give you maximum performance and reliability.

MOMAG - A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag.

Traceability - A guarantee of quality

The keyword for their products is: traceable. 

If you find a little label attached to any Fulcrum product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable.

All this because, devoted to its mission, Fulcrum demands the absolute perfection and safety for its customers.

Syntace X-12

WRS

Features
Triple milled aluminium with MoMag construction: Unique form provides more lateral stiffness. Weight reduction removes rotational weight translating into increased performance.
Oversized nipples in aluminium: Reduce the peripheral mass of the wheel while increasing structural integrity.
Spokes: Double butted stainless steel with reinforced head: Less weight, improved reactivity and stiffness, increased structural integrity.
Hub body: Carbon construction: Provides a high level of lateral stiffness and reduces the weight.
Sealed industrial bearings: Exceptional quality and smoothness; high efficiency over time.
Free wheel titanium body: Reduces the weight of the wheel while increasing structural integrity. Titanium design doesn’t scar- as is often the case with aluminium hubs.
Oversize axle: Aluminium construction: 20mm axle makes for sturdier construction while aluminium structure reduces the overall weight of the wheel.
