This wraps up my Eurobike recaps, and believe it or not, there’s more coming out this week, so look for the usual recap this Friday with lots more great new bikes, components & gear!

  • Specialized Stumpjumper 15
  • Black Math GCode
  • Amflow PL
  • Knolly Warden
  • Orbea Rise Alloy
  • Parlee Taos
  • Giant Revolt
  • Cervelo P5
  • WBR 2-speed

Specialized Stumpjumper 15 is totally wizard

With 6-way adjustable geometry, headset angle, and spring curve, plus a new twin-chamber air shock, the 15th generation full-suspension Specialized Stumpjumper works some serious magic.

The big news is the new Fox Genie rear shock, which has a secondary positive air spring around the primary air spring. For the first 70% of travel, both are working, giving you a higher volume shock with a very linear spring curve. The result is a plusher ride, better traction, with killer small bump performance.

After that, it closes off the outer chamber, immediately shrinking the air volume for more controlled end-of-stroke with higher ramp to avoid a harsh bottom out. Basically, the extra volume lets them tune it for normal riding conditions without the compromises typically required to control bottom out on massive hits and drops, which are much more rare.

Both chambers are adjustable with volume spacers, giving you a lot of tuning options and making it really great for smaller, lighter riders that especially benefit from the larger volume.

As for the rest of the bike, it gets a reinforced shock link that replaces the “Sidearm” design of the prior model, plus their updated SWAT 4.0 door, the option to run it 29er or MX, and a playful ride quality more like a short-travel trail bike, but bump-eating performance of a bigger bike. Electronic drivetrains only. Available in carbon & alloy, $5,500 to $12,000. (VIDEOS: promokeynotecreator storyshock explainer)

Black Math GCode drops the frame, not the seatpost

…and it changes travel, too! The Black Math GCode starts off as an efficient 140mm travel trail bike, but flick a switch and it drops into a 170mm travel enduro bike. The “Upturn Dropper” system has the equivalent of 200mm saddle drop, but with the added benefit of changing suspension kinematics, sag, and head angle, too, whether you’re climbing or descending.

The frame is CNC’d 7075 alloy, which is 100% recyclable and repairable. It fits 29×2.6″ tires, uses 170-180mm forks, works with air & coil shocks, comes in three sizes. MSRP €4,200 for the frameset.

Amflow PL lightweight, full-power eMTB with DJI motor

It’s the first bike using the new DJI Avinox e-bike system, and the Amflow PL eMTB makes full use of it with 850 watts of peak power w/ 105Nm torque and a complete bike weighing just 19.2kg (42.3lbs). Hit Boost mode and that bumps up to 120Nm and 1000W! Available automatic mode switching keeps the assist in the sweet spot when you just wanna ride, and there’s even a “Hill Start Assist” button!

The carbon frame is just 2.27kg, works as a 29er or MX with flip chips, and has a four-bar linkage with 150mm rear travel and 160mm forks. Pricing & availability TBA.

Knolly Warden MX alloy enduro/freeride bike

The 2024 Knolly Warden freeride/enduro bike gets a similar refresh as their other models, with a straight top tube, Enduro bearings, and one-piece rocker arm to stiffen up the rear end. Travel increases to 170mm, matched in the front, and it comes in a new XS size for shorter riders.

It’s a 29/2.75″ MX native build with Super Boost rear axle spacing, but you can also run it full 27.5 by swapping in a smaller front wheel and tire. Complete bikes from $5,199 to $5,999.

Orbea Rise lightweight eMTB gets asymmetric; now in Alloy, too

Orbea’s Rise Alloy eMTB lightweight e-mountain bike gets an entirely new, stiffer, asymmetric frame design to match their Rallon and Occam. Frames are lower than ever, fitting a 200mm dropper on all sizes, up to 230mm on L/XL, and they’re available in SL (140/140mm travel) and LT (150/160mm travel).

They keep the Shimano motors, but upgrade their batteries with custom, ultra high-density versions that pack 16% more power per gram. Choose from 420Wh and 630Wh main batteries, add a 210Wh range extender as needed. Software is updated to provide more power at lower cadences now, with boosts up to 85Nm.

Two carbon models and three new alloy models (shown) with triple-butted hydroformed tubes & polished welds that make them almost indistinguishable from the carbon frames. (video here)

Parlee Taos gravel bike boosts traction & compliance

Following their Ouray all-road bike, the new Parlee Taos gravel bike has a monocoque frame that’s available with a waxed “nude” carbon finish and their new, dramatically sloping frame design. What sets it apart is claims of advanced compliance from the layup and dropped seatstays that improves traction.

It also has a front axle flip chip that lets you change the fork’s rake and axle to crown, letting you swap between bit 50mm gravel tires and 32mm all-road tires and having optimized geometry for each. Which basically makes it two bikes in one. It also gets extra internal downtube storage, frame protection, top tube bag mounts, and stealth dropper routing. Built to order w/ your choice of components, inquire for price.

Giant Revolt gravel bike gets more stealth, more storage

The 4th generation Giant Revolt looks similar to v3 but has a slightly lighter frame and adds full stealth routing, downtube storage, and the ability to use their D-Fuse seatpost for improved compliance or a standard 30.9 round post if you want to add a dropper.

It also gets a rear axle flip chip to adjust wheelbase and chainstay length – shorter for racing, longer for cruising or bigger tires, up to 700×53. Fork, dropout, and top tube mounts let you add bags, but it uses their Overdrive 1-1/4″ to 1-1/8″ steerer, so you can’t easily add a suspension fork. Two models from $5,800 to $7,000.

Cervelo P5 gets slightly faster, lots more comfortable

The new Cervelo P5 triathlon bike also looks strikingly similar to its predecessor, but small refinements make it ~1watt faster on its own. But, it now clears larger 34mm tires, and when they pair it with the latest Reserve 77/88 wheelset and Vittoria 700×29 tires, the combo saves another ~4 watts in rolling resistance and drag.

5 watts may not justify a new $10k+ bike… ha, just kidding. If you’re a triathlete it tooooootally justifies it. But wait, there’s more!

It’s also easier to service and pack thanks to a new, more adjustable one-piece cockpit that also has wider/taller/thicker armrests and pads. The new Fastback seatstay cluster is a lot more compliant so you’re fresher on the run. And it’s UCI legal for TTs, too. Six sizes, four builds & a frameset, includes water bottle, top tube bag, and seatpost bottle cage mount.

World Bicycle Relief Buffalo Utility S2 dual-chain bike

The original World Bicycle Relief Buffalo Bike was a singlespeed brute designed to keep riding for years and years with minimal maintenance while being used to transport people, cargo, food, water, medicine, and more in developing countries.

The problem is, bikes like this are heavy, and even more so when fully loaded, so having gears would be good but it’s hard because they can’t have delicate bits like derailleurs and internally geared hubs that can break under hard use.

Now, WBR has launched a 2-speed, 2-chain drivetrain that uses a special freewheel that shifts by backpedaling, engaging one cog or the other, each with its own chain linked a different sized chainring. All moving parts are internal, and if one chain breaks, the bike is still rideable, and the part is easily replaceable. Your donations help get these bikes where they’re needed.
