Detailed product description

2-WAY FIT
The tubeless technology was first used by the auto industry, then by motorcycles, and has now reached the cycling industry. After its debut with mountain bikes the moment has come to “put it on the road”, and that’s what we propose to do.

We have developed our 2-Way Fit technology to ensure the perfect compatibility of our tubeless rims with normal clincher types. 2-Way Fit road bike wheels are perfectly multipurpose for tackling every situation. Thanks to a special impression in the valve area, the tubes are fitted with the maximum precision while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tyres is also risk-free, with the obvious advantage that there are never any air infiltrations caused by non-ideal positioning when fitting.

The advantages are indisputable: our tests have highlighted a unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy. Tubeless tyres do not suffer from sudden deflation when punctured which is a great advantage in safety terms. There is also no risk of snake bites as there is no tube to get injured. What if a tubeless tyre gets punctured? There’s nothing to be afraid of... With the Fulcrum 2-Way Fit, you can remove the tubeless valve and fit in a standard clincher tire that will let you ride back home.

USB - Ceramic Ultra Smooth Bearings
Fulcrum has quite the reputation for producing extremely high-quality hubs, especially when it comes to smoothness and reliability. The development of new hubs is all done at Fulcrum with an extreme focus on precision.

Hubs with Ceramic USB bearings offer an enormous advantage for road racers and triathletes when it comes to low rolling resistance, weight reduction, and durability.

MOMAG
A system where the spoke nipples can be replaced with a magnet. This is necessary when there are no spoke holes on the outside of the rim.

RIM DYNAMIC BALANCE
The concept is simple and elegant: balance the weight of the valve, with an item of similar weight placed on the exact opposite side.

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.

This results in unwanted flex of the whole wheel and an unavoidable loss of energy. Fulcrum has solved this classic cycling problem with its 2:1 Two-to-One Spoke Ratio patent, by doubling the spokes in the critical zones.
