ingredients for the ultimate strenght and lightness combination:
Low profile lightweight two camber rims have low rotation mass and make you instantly feel the input you give to the pedals.
Straight-pull lacing directly transfers acceleration from drive to tyre.
Radial straight pull spokes give you the highest possible lateral stiffness, please note our hub flanges are specifically designed for radial lacing.
High quality lip seal (not crude o-ring), coupled with oversized 7075T6 axles and cassette's needle bearing are just some of the tricks we employ in our 330gr hubsets.
Avional self locking nipples are highly tensioning black d/b spokes that are carefully gauged for equalized rear wheel tension.
Precisely machined braking surfsces offer longer life (1.5mm rim wall thickness).
Ultra-low rolling resistance Japanese sealed cartridge bearings.
what the press says:
Mountain Biking UK ( June'98) VERDICT: "An excellent, and far cheaper, alternative to Mavic's Crossmax wheelset"
Mountain Biker International (Summer '98) "The impressive poundage was a result of an already light frame deing adorned by Extralite's very own Extraterrestrial wheelset (lighter than CrossMax), saddle and seatpost."
TOTAL BIKE (Dec. '98) " TB rating ***** "
"As light and sturdy as the famous CrossMax, but a good bit cheaper and a damn sight more repairable... The quality of components and finishing was second to none"
"Al especially liked the rims. The first jig checked showed them to be impressively straight and they were still that way at the last check"
VTT magazine (Feb. '99)
"Extralite s'est spécialisé dans la fabrication de composants ultra-giga-méga-extralights. Apres le cadre suspendu le plus léger du monde, Extralite nous refait le coup avec ces roues qui ne pésent que 1 520g la paire."
Ciclismo (Marzo '99)
"Una particolare menzione meritano le ruote Extralite ExtraTerrestrial. Sono tra le ruote complete da cross country più leggere in circolazione. I mozzi hanno perni sovradimensionati... quello posteriore si avvale di un particolare cuscinetto a rulli studiato per gestire gli elevati carichi della cassetta, pesa 265gr."
Maximum mountainbike ( May '99)
"at only 1.520kg for the set (thanks to an ultra-light rear freehub) you will be hard pressed to build a lighter set - especially for the £400"
