Fulcrum Racing Light XLR Clincher Wheelset 2011

In the new version they are enhanced by carbon fibre hub bodies which act on Cronitect steel bearings with CULTâ„¢ ceramic ball bearing technology. Exemplary results: they improve the lightness, the rotation fluidity of the hubs and their life over time.The low profile rim is available for tubular or clincher tyres. It is fitted with *2 radial spokes on the front wheel and *4 on the rear with doubling of the spokes on the freehub side (Two-to-Oneâ„¢ technology) to obtain a snappy response during sprints and uphill. The carbon hub is strong and makes it possible to save weight compared with the aluminium version.

Cultâ„¢
Ceramic Ultimate Level Technology, CULT™. Its the new technical advancement adopted for the most revolutionary crankset in the Fulcrum® range, the Racing Torq™RRS, an unprecedented system which guarantees performance at the maximum level. 

As well as using the best ceramic ball bearings on the market, a new treatment for the races and bearings has been developed with Cronitect® steel using advanced technology from FAG. This leads to the maximum level of resistance to corrosion so that no grease is needed for lubrication.

2:1 Two-to-Oneâ„¢
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 undesirable 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.
