Volagi have two new adventure style disc road bikes built from Reynolds steel. The models are billed Viaje – Spanish for journey, according to the company's Robert Choi – and come in two varieties. The top model will be built from Reynolds 853 and will be available with Campagnolo’s Chorus components for around US$3,200. The 853 frame, which will also be available for sale as a frameset, tips the scales at 3.7lb, with the complete bike around 19lb - Matt Pacocha/BikeRadar
Volagi will use TRP’s Parabox on all of their top-tier models in 2012 - Matt Pacocha/BikeRadar
Tapered head tube; lots of clearance on the fork - Matt Pacocha/BikeRadar

Volagi picked Campagnolo for their new steel Viaje models. Both bikes are built in the spirit of pre-1930s style Tour de France adventurers. Choi called them “total road machines” built for adventure road cycling with clearance for big tires, but with short chainstays and geometry meant for the road. Features include Volagi's comfort-adding Longbow Flex design, a tapered head tube, rack and fender mounts, PressFit BB86, and seven sizes spanning 47cm to 62cm - Matt Pacocha/BikeRadar
We continue our tech coverage from the Sea Otter Classic with yet more bikes from the grounds of the Laguna Seca raceway. Yeti showed the latest version of their stunning 303 WC Carbon downhill machine (while a show attendee simultaneously paraded one of the company's oldest bikes) and Nukeproof had their new Rook slopestyle chassis on hand. Look out for a full Superbike feature on the latter in an upcoming issue of Mountain Biking UK magazine.
Carbon fiber 29er hardtails are still on the rise, with new models from Fuji, Haro and Stevens, and Ellsworth added more carbon to their Moment, Evolve and Epiphany chassis. Meanwhile, road and cyclo-cross riders got a look at Volagi's latest disc-equipped road bikes, Calfee's new Power Bar hidden Di2 battery system, Origin8's bargain Lactic Acid crit racer and Breezer's iconic steel Venturi. Finally, for every trail-loving parent out there, Lil' Shredder introduced just the thing for toddlers who are already faster than we are. Check out our image gallery for a look at all these bikes and more.
