Yeti's race team transports tires in this custom hand truck, which can move up to 60 tires in one convenient package. Hopefully they don't need the one at the bottom any time soon, though.(Image credit: Jonny Irick)
Yes, this bike was as sketchy as it looks. We got a closer look at it later at the show and it was held together with an equal mix of weld bead and zip-ties.(Image credit: Jonny Irick)
Origin8 admits that the rear end of the Lactic Acid is quite stiff, making it a better choice for crit racing than all-day road rides.(Image credit: Jonny Irick)

ISCG tabs on a 20"-wheeled kid's bike? Why not, according to Lil' Shredder.(Image credit: Jonny Irick)
Lil' Shredder frames aren't just some cheap frame made in Asia - we're told they're welded in California by Ventana.(Image credit: Jonny Irick)
Sliding dropouts on Lil' Shredder frames supposedly accommodate either 16" or 20" wheels.(Image credit: Jonny Irick)
Lil' Shredder offers big performance in pint-sized packages. We dare say every industry dad will want one of these for his kids.(Image credit: Jonny Irick)
The 650b Jamis Dragon steel hardtail sports a gusseted head tube area.(Image credit: Jonny Irick)
Stevens' new carbon 29er hardtail was yet another of the new breed of hardtails to use a press-fit BB92 bottom bracket shell to provide more tire clearance.(Image credit: Jonny Irick)

Ellsworth has moved to a tapered head tube for the next-generation Dare.(Image credit: Jonny Irick)
Ellsworth showed the latest prototype for the redesigned Dare downhill racer. Key changes include a lower and slacker geometry, a bigger seat tube, and a stiffer front end.(Image credit: Jonny Irick)
Lots of welds going on in the bottom bracket area of Ellsworth's revamped Dare downhill frame.(Image credit: Jonny Irick)
Calfee's road tandem uses a Gates belt mounted on the right side, meaning the bike uses two standard cranks instead of a dedicated (and typically heavier) tandem setup.(Image credit: Jonny Irick)
Calfee showed off this stunningly lightweight carbon tandem at the Sea Otter Classic.(Image credit: Jonny Irick)
Calfee's new PowerBar (we're gussing that name is going to have to change) tucks a Shimano Di2 battery inside the handlebar end. The charge port is conveniently located right on the bar plug.(Image credit: Jonny Irick)
Production versions of Calfee's new 'artist series' of bikes will be clearcoated. This one was fresh from the artist and wasn't quite finished.(Image credit: Jonny Irick)
Calfee also debuted a new 'artist series' of paint jobs at Sea Otter. Each frame is painted by artist Krusch Rhoades and only ten of each scheme will be made.(Image credit: Jonny Irick)
The new hybrid carbon fiber/bamboo bottom bracket construction from Calfee provides the necessary strength for modern 29er chain stay geometry.(Image credit: Jonny Irick)
Calfee showed off this new hybrid bamboo/carbon fiber 29er. The different colors of bamboo help identify the different origins. The lighter stuff is sourced from the Yucatan and is heavier but stiffer.(Image credit: Jonny Irick)
Joe Breeze says the curved stays his Venturi steel road bike improve the ride quality and enhance brake performance.(Image credit: Jonny Irick)
An ovalized seat tube boosts bottom bracket stiffness on the Breezer Venturi.(Image credit: Jonny Irick)
Breezer contends its Venturi model is one of the last steel road racing bikes available off-the-shelf.(Image credit: Jonny Irick)
Joe Breeze says the D-Fusion shaping on his Venturi road bike adds strength to the front end.(Image credit: Jonny Irick)
Despite the traditional steel construction, even Breezer has moved to a press-fit bottom bracket for the Venturi model.(Image credit: Jonny Irick)
Boo Bicycles was among several companies at Sea Otter making use of Gates' latest CenterTrack belt drive.(Image credit: Jonny Irick)
The heavily reinforced seat tube mast is now sized for a 30.9mm seatpost instead of the smaller 27.2mm one used on the previous Ellsworth Dare.(Image credit: Jonny Irick)
Ellsworth has refined the molding process for the Enlightenment 29er carbon hardtail.(Image credit: Jonny Irick)
While the Ellsworth Enlightenment looks identical on the outside to last year's version, new internal molds apparently have strengthened the rear end.(Image credit: Jonny Irick)
Haro will offer carbon fiber 29er frames with several different build kits but the same frame throughout.(Image credit: Jonny Irick)
BB92 press-fit bottom brackets are quickly finding favor among the carbon 29er hardtail crowd since they allow for wider stays and more tire clearance as seen on this new Haro.(Image credit: Jonny Irick)
Haro showed off new carbon fiber 29er hardtails at the Sea Otter Classic.(Image credit: Jonny Irick)
Fuji previewed the new Altamira CX Disc at Sea Otter.(Image credit: Jonny Irick)

Ellsworth has tucked IS-style rear disc brake mounts inside the rear triangle on the Roots 'cross frame. Hub spacing remains 130mm.(Image credit: Jonny Irick)
The Ellsworth Roots gets a disc-compatible rear end but was shown with a disc-free fork.(Image credit: Jonny Irick)
Ellsworth is now including these carbon stays on the Evolve, Moment, and Epiphany models.(Image credit: Jonny Irick)
Ellsworth's new carbon rear end incorporates post mount disc tabs and a 142x12mm thru-axle. The internal brake hose routing is perplexing, though.(Image credit: Jonny Irick)
The Ellsworth Evolve is among several models to use the new carbon fiber seat stays.(Image credit: Jonny Irick)
Boo Bicycles showed off this remarkably light bamboo-tubed belt-drive singlespeed just outside the Enve Composites booth.(Image credit: Jonny Irick)
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.
