With gravel still one of the fastest-growing segments in cycling, tech development is continuing at a rapid rate of knots.We've been scouring the booths of the Sea Otter Classic, North America's most important cycling show, for new gravel tech.Here are six new or unreleased gravel tech highlights from Vittoria, Giro, Redshift, Wolftooth, Cinelli and Cane Creek.Vittoria teases new gravel tyre line with prototype Terreno T50This Terreno T50 prototype was hidden away on Vittoria's booth. - George Scott / Our MediaTucked away on Vittorias stand was this prototype Terreno T50 gravel tyre.The Terreno name is well-established in Vittorias tyre range, with Wet, Mix, Dry and Zero options in the range, offering decreasing amounts of grip.The T50 has a new tread pattern. - George Scott / Our MediaVittoria appears to be moving towards a new nomenclature, with the T50 sitting in the middle of a hypothetical gravel scale that runs from 0, for dry, fast conditions, and 100, for the grippiest, most extreme gravel tyre.The T50 is a fresh take on the existing Dry, but with a hex-shaped tread pattern running along the centre of the tyre (the Dry currently uses a fish-scale design) and more space between the shoulder lugs. Its described as having the DNA of the Dry" but in a more aggressive, mix-tread design.Expect the 'T' naming convention to roll out across Vittoria's gravel tyres. - George Scott / Our MediaDoes this mean Vittoria will be renaming its existing tyres and adding additional options on the new T scale? Vittorias representative at Sea Otter remained tight-lipped but wed guess so.Giro is preparing to launch two new shoes for XC and gravelComing soon from Giro: the Gritter (bottom) and Empire SRC (top). - George Scott / Our MediaGiro has two new XC/gravel shoes coming later this year, with the Gritter and Empire SRC both slated to arrive late summer-early fall.This is the Giro Gritter. - George Scott / Our MediaThe Gritter is a bit lighter (and a bit more expensive) than the Empire SRC, though we dont have weights for either of the pre-production models on show at Sea Otter.Two BOA dials provide micro-adjustable closure. - George Scott / Our MediaThe Gritter uses a version of Giros Syncwire upper, with breathable mesh panels bonded into a lightweight TPU fabric.The Gritter combines a carbon sole with a rubber outer. - George Scott / Our MediaTwo BOA dials take care of retention and, of course, offer on-the-fly adjustment.The two toe studs on the sole are kept in place with bolts that can be used as spares should one of your cleat bolts go awry.This is the Giro Empire SRC. - George Scott / Our MediaThe Empire SRC has a more traditional upper, with perforations for breathability, and uses laces for retention.Both shoes have a carbon composite sole with a rubber outer.The Gritter is expected to cost $375, while the Empire SRC is due to come in at $350.Perforations for breathability. - George Scott / Our MediaRedshifts Top Shelf riser bar combines comfort and practicalityA novel take on the riser bar from Redshift. - George Scott / Our MediaHeres a fresh take on the humble riser bar from Redshift, the company best known for its suspension stems and suspension seatposts.The Top Shelf is available with 50mm or 70mm of rise, with the top of the bar lifting your hand position on the bike, and the bottom of the bar providing the clamping area.Redshift will offer options with 50mm or 70mm of rise. - George Scott / Our MediaThe 25.4mm-diameter bar also opens up more room for mounting accessories. Speaking of which, Redshift has designed a new bar bag for the Top Shelf, designed to clamp onto both the top and bottom section of the handlebar, for added stability.Redshift has developed this new bar bag for the Top Shelf. - George Scott / Our MediaThe bag has a magnetic closure at the top, meaning you can slide a hand in to grab snacks without having to fiddle with a zip or velcro fastening.Back to the handlebar, and its available in 44cm, 47cm, 50cm and 53cm widths, with 25 degrees of flare.The magnetic closure provides easy access. - George Scott / Our MediaRedshift is also planning to add a narrower 41cm bar, and is looking to introduce a 10-degree flare option, too, for more performance-orientated riding.The bag attaches to the top and bottom of the bar. - George Scott / Our MediaWolftooth gets aero with one-piece chainring for SRAM cranksWolftooth is expanding its range of aero chainrings. - George Scott / Our MediaHaving introduced an aero chainring for Shimano GRX earlier this year, Wolftooth is back with a slippery option for use with SRAM cranks.The narrow-wide chainring is designed for SRAMs eight-bolt direct-mount standard, and will come in 46, 48, 50 and 52-tooth sizes for 1x drivetrains.Wolftooth is also planning to add a chainring for use with SRAMs AXS power meter spider.Pricing for the new aero chainring is expected to start from around $94, though this is to be confirmed.Cinellis updated Neo Gravel has 20mm of suspensionCinelli has updated its Nemo TIG Gravel frame. - George Scott / Our MediaOkay, this one isnt completely new, having launched towards the tail-end of 2023, but youll forgive us.The Nemo TIG Gravel is Cinellis updated gravel frame, made from custom-drawn, triple-butted Spirit tubing from Cinelli's sister company, Columbus.The redesigned chainstay yoke increases tyre clearance. - George Scott / Our MediaThe seatstays and chainstays have been reshaped to accommodate a 700x47c tyre, characterising this as a bike for the more adventurous end of the gravel spectrum.On a similar note, there's also 20mm of travel up front thanks to the Hi-Ride Sterra fork, which we first brought to you in 2022.The Hi-Ride fork provides 20mm of bounce. - George Scott / Our MediaAn adjustment dial for the fork sits on top of the stem, offering the option to lock out the suspension.Theres also a nod to comfort at the rear of the bike, with the seatstays shaped to add some flex, according to Cinelli, and dropped a little down the seat tube, compared to the previous Nemo.Cane Creek's Invert gravel fork breaks coverThe Cane Creek Invert is one of the biggest talking points at Sea Otter. - Scott Windsor / Our MediaWith the Cane Creek Invert launched only a couple of days before the show, Sea Otter has provided the first opportunity to see the new gravel fork.The Invert is, as the name suggests, an inverted gravel fork, whereby the uppers slide over the lowers, reversing the design of a conventional suspension fork.The uppers slide over the lowers. - Scott Windsor / Our MediaCane Creek has rather controversially described the Invert as the worlds first gravel fork. Now, clearly there are lots of gravel forks out there already weve reviewed most of them but Cane Creek says theyre not fit for purpose, claiming the current options are either too firm or offer too many adjustments that simply arent needed for gravel.A closer look at the internals. - Scott Windsor / Our MediaThe Invert is, the brand says, a Goldilocks solution, with options for 30mm of suspension travel (the Invert SL, claimed weight 990g), or 40mm of bounce (the Invert CS, claimed weight 1,113g).Weve covered more of the thinking behind the Cane Creek Invert in our news story from the launch.
