Shimano 105 Mechanical & GRX 12-speed debut

Shimano unveiled two new mechanical 12-speed groups this week – 105 for the road, and GRX for gravel. I wrote a longer tech story covering all the details if you’d like to dive deep, but here’s the gist of it:

GRX 12-speed:
Massive increase in gear range with new 10-45 and 10-51 cassettes for 1x (450% & 510% range, 40- & 42-tooth chainrings), and a slightly larger 11-36 cassette for 2x (506% range with their 48/31 double). The 1x rear derailleur gets two different cages that can be swapped to fit either cassette. Shifter hood shape is flatter on top for better ergonomics.

Their carbon gravel wheels get a lot lighter, too, dipping under 1,400g thanks to new hubs. Overall, it’s a great refinement of an already good gravel group with a much-needed boost in gearing options.

105 Mechanical:
Basically a mechanical version of the recently released 105 Di2 12-speed group, with the same ergonomic, lever reach, and pad clearance updates, all with the same great looks and performance that make it an excellent value.

Mason Bokeh 3.0 goes green

The recently updated Mason Bokeh 3.0 gets the GRX upgrade along with this limited edition Optic Green colorway. It’s a Dedacciai alloy frame made in Italy and has tons of mounts. They also gave their Resolution steel road bike the new 105 and painted it in a very pretty Sepia.

Mosaic upgrades their mountain bike

Colorado’s Mosaic Cycles’ new MT-1 is a better version of their batch-built MT-2, getting lighter double-butted 3/2.5 titanium tubes. It comes in four sizes with custom geometry available at no upcharge (it’s still $6,600 for the frame, so…).

XC to trail geo is tuned for a 120mm fork with 29×2.4″ tires, but works with 110-130mm travel and clears up to 2.6″ tires. Brake, shift & dropper routing can be internal or external, up to you. They’re made to order with 6-week lead times. Bike shown here is $13,575.

Sage PDXCX cyclocross bike gets upgraded, too

The latest Sage PDXCX keeps its PNW style with high BB and aggressive stance, but updates to more modern standards throughout. New 3D-printed dropouts (not shown on this one) are UDH/T-Type compatible and give it flat mount brake mounts.

The BB upgrades to T47, which makes room for all cables/hoses to run internally through the downtube, making the bike easier to clean and shoulder. Tire clearance grows to 40mm, making plenty of room for “fast gravel” or commuter tires if your ‘cross bike pulls double duty year ’round.

Time ADHX 45 Dyneema-infused gravel bike

2023 time adhx 45 gravel bike with woven carbon and dyneema fiber tubes

Time’s new ADHX 45 gravel bike uses their in-house braided carbon fiber tubes with Bio-Based Dyneema woven in, which they say nearly doubles the frame’s strength. It’s also extremely light and eco-friendly to produce.

Compared to their ADHX Allroad bike, this gravel version increases tire clearance to 45mm, +15mm longer wheelbase, +10mm longer chainstays, and +3mm more fork offset. It’s 1x/2x & mech/elec drivetrain compatible, has forged carbon dropouts, and stealth internal routing through Deda DCR headsets. Frameset $3,599, bikes from $5,719 to $8,169.

Columbus Trittico integrated cockpit & fork is brilliant

Right now, custom builders have a few (albeit very good – ENVE, FSA, Deda) options for stealth routing. Now, Columbus, which has been a long-time tube and fork supplier to the handmade bike crowd, has a complete cockpit component line called Trittico.

The carbon handlebar and stem run all lines internally, feeding alongside a “Trefoil” shaped fork steerer that doesn’t need holes (except for the front brake hose) and allows for standard 1-1/8″ upper headset cups. Technically, this means you should be able to convert your own road bike to stealth routing with these parts, too.

A magnetic cover hides direct-mount bolts for flat mount brakes, so there’s no adapter needed. The handlebar has ergo shaping on the tops and drops and weighs just 243g. The stem fits over a tuning sleeve on the steerer to allow for +/- 5º angle adjustments, and all faceplate mounting bolts insert from the bottom and are completely hidden from view. Well done, Columbus! (videos of each component on their Instagram)

Specialized’s partially 3D-printed Power Expert Mirror saddle

Specialized’s top-level Mirror saddles have a fully 3D-printed top with no cover to hide the lattice structure and range from $325-$450. The new Power Expert Mirror puts that 3D padding only under your sit bones and drops the price to $200.

It’s also available in four widths (130/143/155/168mm) with weights from 210-227g thanks to hollow titanium rails. Standard PU foam surrounds the Mirror sections with a waterproof cover on top and long center relief cutout.

Abbey Bike Tools Star Nut Setter

Abbey Bike Tools’ new Star Nut Setter is a two-piece design that slides an outer sleeve over your steerer tube to guide the inner driver straight down the pipe. Just thread the star nut on and tappy tap tap until it hits its stop for a perfectly aligned install at the perfect depth.

Works with 1″ & 1.25″ metal steerers. It’s not for carbon steerers because don’t ever put a star nut in carbon steerers, mmkay? They’re $60 and will be anodized green (I spotted these at their factory in an early production state).

Wolf Tooth Morse Cargo Cage

Wolf Tooth’s Morse Cargo Cage uses the same dot-dash mounting holes as their water bottle cages to give you 35mm of vertical positioning flexibility, now in a bigger three-bolt “anything” cage design. Additional side mounting holes let you angle them however you want, too.

They’re machined from 5052 aluminum in Minnesota, weigh 60g each, and measure 7″ x 2.8″. Optional 20″ straps are 28.5g. MSRP is $39.95, straps are $8.95, or bundle the cage + 2 straps for $51.95. Max load capacity is up to your fork’s limits.

Sun-Ringle SR32 trail wheels extend to kid’s bike sizes

sun-single SR32 trail MTB wheels have small 20" 24" 26" sizes for kids mountain bikes

Sun-Ringle’s new SR32 trail wheels get 32mm wide (internal) alloy rims and come in Pro & Expert 29″er”/27.5″ models for adults, with SRX and Super Bubba X hubs.

More interesting are the youth options, with 24″ and 26″ for aftermarket, and 20″ for OEM, giving kids a better option for shredding hard. They have QR, standard & boost axle options, plus XD, HG & Micro Spline freehubs, so they’ll fit anything (and make it easier for you to pass down your old group).

Specialized Globe Haul LT e-cargo bike gets bigger

The new Specialized Globe Haul LT is a long-tail version of the original, doubling the rear end’s length and increasing cargo capacity to a massive 441 lbs. Now there’s room for six panniers (they make a ton of accessories, like these baskets…dogs not included) or two small friends.

The one-size-fits-most (4’5″ to 6’4″) bike rolls on 20×3.5″ tires for a low center of gravity, has front & rear lights, full fenders, assists up to 28mph, and has an optional throttle add-on that lets you cruise w/o pedaling at up to 20mph. The 700W hub motor and 772Wh battery deliver up to 60 miles of range. MSRP $3,500, accessories sold separately.

Cannondale launches Wonderwagen & Cargowagen e-bikes

Meanwhile, Cannondale also launched new e-cargo bikes. The front-loading bakfiets-style Wonderwagen Neo has a two-seat box with massive headlights and a foot rail that keeps it from tipping over. Pull the seats out to increase cargo space. Low standover and a dropper seatpost make it easy to mount even when loaded. Available in select countries but not the U.S. (video here)

The Cargowagen Neo ($4,300) is a standard e-cargo bike also fits up to two kids with 176 lbs of cargo (plus rider, so probably similar to the Globe). Both use Bosch Cargo motors, can fit a second battery, have suspension forks, and roll on 20″ wheels.

Parting Thoughts

We cyclists love to complain about new standards.

“The companies just wanna sell us more stuff!”

Maybe, but I love new stuff. If you’re reading this newsletter regularly, you probably love new stuff, too.

Does anyone really prefer rim brakes after trying disc brakes? Or tubes after going tubeless?

What if nothing changed? If the Gatorade Sports Science Institute has been studying human performance and hydration since 1985, why hasn’t the formula seen more than a couple of trivial updates since it launched in 1965? Did they really get it right the first time around?

Were 26″ wheels really the ideal for mountain bikes?

Should road bikes still run 23mm tires?

No, no, and no.

If you think things are changing too much, too fast, think about this:

When SRAM launched their XX 2×10 group in 2009, it was an intentional step toward 1x drivetrains. They were already working on 1x groups and knew they were the future.

But can you imagine if we had gone from 3×9 groups with a tiny cassette to 1x with monstrous 50-tooth cassettes? Everyone would have lost their sh*t.

No joke, I’ve seen an entire dumpster full of MTB front derailleurs. So, should they have just skipped XX altogether? In hindsight, it’s easy to say yes, but…

Would we have accepted radical change? Or did we need the baby steps of logical change?

Would we have accepted 120mm “XC race” bikes if we hadn’t gone from 60mm to 80mm to 100mm first?

Here’s to the next new standard!
