Factor Ostro VAM lightweight aero road racing bike

Already taking the “W” under Stevie Williams at the 2024 Tour Down Under, the new Factor Ostro Vam improves upon aerodynamics, comfort, and stiffness to become their ultimate race bike. To make it more aero, they redesigned the fork, headtube, top tube and seatpost, dropping 70g of drag for a 7w savings, with benefits improving at 5-10º yaw angles.

Custom bottle cages are designed to be most aerodynamic without a bottle (seriously), giving you an extra edge when you toss them for those finish line sprints.

It’s designed around wider 700x28mm tires and comes with Black Inc’s 48/58 wheels (1,270g). The frame is down to 820g, giving them a complete bike under 6.8kg, which is 267.8g lighter than prior model. Framesets $5,499, bikes from $8,099 to $11,499.

Polygon Tambora transforms between road & gravel bikes

By using flip-flop dropouts and swappable brake mounts on both the fork and frame, the Polygon Tambora can switch between road and gravel geometry, adjusting tire clearance to match, up to 700x45in gravel mode, and 700×35 in road mode. Wheelbase, head angle, chainstay length all changes to suit the terrain and tire size.

Carbon and aluminum frames offered, all with four bottle cage mounts, frame bag mounts, and rear rack/fender mounts (14 total!), but oddly no fork leg or top tube bag mounts. Available at BikesOnline in North America, starting at just $899!

Mosaic GT-1 iAR all-road gets integrated, bigger tires

The Mosaic GT-1 iAR (for integrated All Road) titanium bike is the latest variant, getting a fully integrated brake hose setup thanks to the ENVE IN-route bar, stem, and fork combo. Tire clearance jumps to 700x40mm, up from 38cmm, but it keeps the same size- and rider-specific tube selection and full custom geometry they’re known for. Custom finishes and paint also available.

Lauf Seigla gets new moss green color & SRAM Transmission builds

The Lauf Seigla gravel bike has a beautiful new satin Moss Green color option, joining white, black, blue and pink. It also has a new RACE Transmission build, pairing a SRAM XO T-Type derailleur and cassette with Force AXS cranks, shifters, and brakes. The complete bike is just $4,790 with e*Thirteen carbon wheels, FSA post and stem, Lauf Smoothie carbon handlebar, Maxxis tires, and Fizik saddle.

Revel Tirade titanium all-mountain hardtail MTB

The new Revel Tirade is a long travel (140mm forks) titanium hardtail all-mountain bike, with a shapely frame designed to mute the rough stuff and trail chatter. The frame is 3/2.5 ti tubing with CNC’d 6/4 dropouts, claimed weight is 5.05lbs (2,290g) for size M.

It has a low standover and short seat tube to fit longer dropper seatposts, slack 64.7º head angle, and sliding dropouts give you 17mm of chainstay length adjustment. Use that to fit bigger tires, or tighten it up for sharper handling, or go singlespeed. Complete bikes from $5,199 to $9,599, frameset is $2,499.

Privateer 141/161 trail-to-enduro bikes get all-new suspension design

Three years in development, the 2nd gen Privateer Trail and Enduro mountain bikes debut with an all-new A-L-P suspension platform. Featuring 141mm and 161mm rear travel, respectively, A-L-P (Aligned Linear Progression) claims be very supple at the beginning, a linear coil-like feel even with air shocks, and great pedaling support throughout the entire gear range. It’s also stable under braking and has good bottom out resistance.

In other words, magic, but in a simple Horst Link design that stays true to their “working man’s” credos of easy serviceability and affordability. They also give it oversized Enduro Max linkage bearings for better durability, plus size-specific chainstay lengths, adjustable rear center, and flip chip to go MX style, and full insertion seatpost for extra-long droppers.

Chris King DropSet 6 headset for straight 1-1/8″ DH steerers

Designed for straight 1.125″ steerers found on double-crown downhill mountain bike forks, the new Chris King DropSet6 headset uses their GripLock upper bearing cup design to keep things tight.

The GripLock design uses a split wedge on top of the upper bearing that tightens if the bearing tries to slide upward, preventing it from getting knocked loose on rough terrain. Available in all 10 anodized colors, MSRP $176 with steel bearings, or $296 with ceramic bearings.

Enduro MaxHit T47 bottom brackets

Enduro’s MaxHit bottom brackets use a full 440C stainless steel construction with the shell serving as the outer bearing cup. This design makes room for larger balls, which mean smoother spinning, and the extra-strong material means much stronger, longer-lasting service life. Basically, these should outlast your bike.

Between the bearings is an alloy (not plastic!) sleeve to prevent compression, with O-rings to allow for minor frame intolerances. These new T47 threaded BBs come in three types (L-to-R: External, Asymmetric, Internal), each with DUB, 30mm & 24mm spindle options. Available in March for $179 w/ lifetime warranty.

C-Bear’s shiny ceramic solid pulleys for Shimano GRX

The new C-Bear OCMX (Original Cage MaX) Rainbow Aurora Hybrid pulley wheels use a solid 7075 aluminum disc to prevent crud from building up or sticks from jamming them, which also makes them easier to clean. These roll on double sealed ceramic bearings and are designed for Shimano GRX, supposedly fitting in the stock cage despite having much larger 12/16 tooth combos.

They also make them in 12/13-teeth for Shimano & SRAM 12-speed road and gravel derailleurs, both fitting in stock pulley cages with no other modification necessary. MSRP €139.

Park Tool adds e-bike specific tools

The new Park Tool EWS-2 three-way wire and cover popper helps guide and install Di2 wires safely, with a flat, rounded edge perfect for unscrewing coin cell battery covers. MSRP $9.95.

The LRT-5 Lockring Tool removes the crank arms from Fazua Ride 60 motors, with a 3/8″ ratchet handle fitting and 36mm wrench flats so you can attach the lever of your choice. MSRP $33.95. They also have a new SW-6 spoke wrench for larger 3.7mm spoke nipples, which are found on some hub-driven e-bikes.

Giro Coalition Spherical full face helmet is just 800g

The all-new Giro Coalition Spherical uses a unique combination of EPP (softer expanded polypropylene, rather than harder EPS/expanded polystyrene) and elastomer bushings where it attaches to the main helmet to add up to 60mm of compression to the chin bar without breaking it. It appears to stick out a little further than normal, but…your good looks are worth its mildly funny looks.

An 800g weight and 25 vents & internal channeling make it light & breezy enough for trail riding. It has MIPS Spherical, 12mm thick padding, removable chin pads (two sizes included), adjustable breakaway visor, and meets CE/CPSC/ASTM DH/BMX/NTA safety standards. MSRP $325, comes in four colors. (Available at Backcountry.com)

Specialized Propero 4 helmet & Torch 3.0 shoes are more approachable

Combine the S-Works Evade’s aerodynamics with the Prevail 3’s ventilation and you get the new Specialized Propero 4 road helmet. It’s aero (4w faster than Prevail 3), well-vented, and lightweight (just 290g, Medium CE), and it earns a Virginia Tech 5-Star safety rating. Small micro-channels swirl the air as it passes inside the helmet, enhancing cooling. MSRP is $200, much less than those other two helmets, too.

The S-Works Torch are some of my favorite road shoes – light, and very comfortable. The new Torch 3.0 shoes ($250) share the same single-layer, seam-free upper and wider last, but gets slightly lower-level BOA Li2 dials (still with two-way micro-adjust) and loses the titanium cleat hardware, but get much larger rubber toe and heel pads for safer walking. A new Torch 2.0 ($180) brings the price down further with a single BOA Li2 dial.

Trek debuts comfy METNET knit cycling shoes

At the top of the new line, the Trek RSL Knit (top left, $499) gets a knit upper with sock-like fit and feel, but with support straps, dual BOA Li2 dials, and a 100% OCLV carbon sole to lay down the power. The insole is made from a bio-based EVA foam alternative called Rise by BLOOM. (video here)

The Trek RSL Road (top right, $449) has a more traditional fit, feel and look from the synthetic upper, but with huge knit METNET relief zones. It has the same BOA Li2 dials and OCLV sole.

The new Velocis (bottom right, $249) updates one of their most comfortable all-around performance shoes with METNET relief zones, an OCLV carbon-composite plate, and dual BOA Li2 dials.

All three work with their updated BioDynamic Cycling Insoles ($44.99/pair, sold separately), which come in various arch support levels and are made by Superfeet with 70% recycled material.

Swiss Side AERO cycling socks

Following the triathlon AERO calf sleeves launched last summer, the new Swiss Side AERO cycling socks use the same laterally ribbed textile upper, but with a UCI-legal cuff height (half the distance from ankle to knee). Despite the shorter stature, they deliver a claimed 3-6.5 watts at 45km/h (28mph).

The foot is an ultra lightweight, wicking mesh, and they’re only available in white because dyes and sublimation hurt both aerodynamics and breathability. Available in S/M/L sizes for €69.

Rudy Project Astral full coverage, Rx-ready cycling sunglasses

The new Rudy Project Astral have a bit of a retro flair without getting ridiculous, offer full wrap-around 6-base curve lenses, and work with their prescription eyewear insert. Frames are Rilsan Clear, a bio-plastic made from 45% castor oil, with soft, grippy temples and nose pads. They’re just 26g, MSRP $189.99, six frame/lens colors.

FasCat CoachCat AI provides instant training feedback

FasCat founder and coach Frank Overton has trained athletes for years, and now he’s trained an AI to do it for him. The new CoachCat AI provides an instant analysis of your ride (or run), giving you feedback in seconds rather than days or weeks, to help refine your training plan in real time.

It’s also cheaper than hiring a meat-based coach, just $34.99/mo (or $299/yr). FasCat also looks at HRV and sleep data from compatible smart watches & wearables, providing advice on rest and recovery, too.

Wandrer makes a game out of exploring by bike

Much like Strava gamified outdoor cycling with KOMs and segments, Wandrer gamifies your Strava uploads by rewarding you for riding new roads. Join for free and it analyzes your most recent 50 rides (as long as you post them to Strava) and shows your total ride map.

You earn achievements every time you ride new roads or places, but the real reward is showing you how little of your hometown you’ve probably ridden and the encouragement to get out and explore more. Upgrade to a paid account and it’ll process everything you’ve ever uploaded. (h/t to Michael F. for sharing this!)

Small Bites

Hot Deals

There are TONS of big deals this weekend, from bikes to gear to components. Some only last through Sunday or Monday, and Kona’s deal runs out when the bikes do, so get on it.

Parting Thoughts

I’ve been thinking about The Lunch Ride a lot this week.

I like to create cool shit and then, assuming it people like it, figure out the business side later.

Real Field of Dreams, I know.

Based on the kind replies I get each week (Thank You!!!), I think I nailed the first part.

Now it’s time to get the industry on board to support this.

A couple of weekly recaps in March have a sponsor.

It’s a good start, but I need more. So if you’re in the cycling industry and appreciate the coverage you get, please reach out (just hit reply).

If your only connection to the cycling industry is putting a bike between your legs and pedaling it, that’s cool, too. And thanks for filling in my survey about getting some Lunch Ride cycling caps and T-shirts…looks like that’s a GO, so stay tuned.

If you didn’t see that survey, click here to let me know what you’re interested in. It’ll be a very limited run.

Thanks, and have a great weekend!
