TAIPEI, TAIWAN – March 20, 2013 – Wilderness Trail Bikes (WTB) released a new rim family, dubbed the KOM, for 2014 expanding their TCS rim assortment to 3 families composed of 16 individual rim offerings. The KOM rims feature a 23mm inner rim width and 28mm outer, WTB’s proprietary WT69 Aluminum Alloy, 4D angled drilling, and carbon weights at an Aluminum budget in 26”, 650b, and 29” sizes.
Like the new Vigilante tire, KOM rims have spent plenty of development time underneath Team WTB riders Mark Weir, Jason Moeschler, and Ben Cruz during the 2012 season dominated by enduro race events. Enduro racing’s emphasis on speed descending yet requirement for an untimed, pedaled ascent, has created a need for rims that save one’s legs uphill, yet provide a wide enough profile for aggressive, all-out descending. WTB’s KOM rims fill this need and bring professional, race quality rims to the discerning general public heavily influenced by carbon marketing.
“KOM rims give you an All Mountain profile and stability at a low cross county weight,” explains Chris Feucht, WTB’s Product Manager. “It’s kind of an anomaly, KOMs have an amazing width to weight ratio that rivals carbon without having any rider weight limits, like many other light-weight aluminum rims.”
KOM rim weights are on par with carbon rims of the same width. To put things into perspective, a KOM i23 (the i23 stands for internal 23mm) in 29” flavoring tips the scales at a mere 426 grams. 650b KOM i23s weigh in at a scant 401g while 26”, still proving to be the favored wheel size by most enduro racers, squeak past at a low 385g of rotational weight.
WTB attributes these head-scratching, second glance worthy weights to further advancements made in WT69 Alloy capabilities. WT69 Alloy is 20% stronger than 6000 series Aluminum, allowing for such scant weights without any loss to overall rim strength. 4D drilling – aligning the spoke hole departure angle to that of the hub flange, further reduces overall weight by eliminating the need for eyelets. WTB’s product development team found that rim and wheel longevity increased significantly using 4D drilling due to the elimination of lateral loads placed on the spoke head and nipple junction, traditionally the most common area of spoke failure.
