April 1st, Boulder, CO— The Wheel Industry Manufacturers, Planners & Suppliers committee, part of the cycling industry’s international standards group, announced today it will premiere a new open standard for mountain bike wheel size—the 28.125” or V-8 (named after the powerful automobile engine, not the vegetable juice cocktail).
A press conference and public unveiling is scheduled for Day 2 of the Sea Otter Classic on Friday, April 20th.
“The new V-8 standard builds on the work done by Kirk Pacenti who pioneered the now-standard 27.5 or “Tweener” size back in 2007,” said group chair Jürgen Mondlicht. Dr. Mondlicht is also president of the German wheel company Mondlicht Räder GmbH.
“That was more than a decade ago,” Mondlicht continued. “The beauty of the 27.5 or 650B (ISO 584) standard was that it split the difference between the old 26” (ISO 559) rim and the subsequent 29” or 700c (ISO 622). By further splitting the difference—this time between 27.5 and 29”—our engineers have determined the new 28.125” or V-8 (ISO 603) delivers the best of both worlds in terms of angle of attack, precise handling and superior tread grip. It will also offer consumers yet another a new wheel size option and force dealers to inventory another line of bikes for every brand they carry.”
In addition to the premiere at Sea Otter, Mondlicht says the new standard will be featured on select 2019 model year bikes offered by many major brands.
Test V-8 bikes will be available for press and attendees at Sea Otter.
Contacted by telephone, a WIMPS spokesperson denied rumours the group was already at work on an even newer size, the 28.5265.
