Center Channel Hole This is a required option.

WITH HOLES: This is the traditional method. Holes are drilled in the center channel to allow the nipples to easily be fed through the rim. Tubeless tape is required to seal the rim.

WITHOUT HOLES: No holes are drilled in the center channel. Feeding the nipples through the rim is more challenging, but it allows for a tubeless setup without the need for tape. This kind of system is known as "road tubeless" and was made popular by Mavic. Some companies still refer to it as "UST style", however, UST is actually a specific interface between the tire and rim which was developed by a partnership between Mavic, Michelin, and Hutchinson.

Valve Stem This is a required option.

We include enough valves to cover your individual rim purchase. We use a lightweight black alloy anodized valves with an oversized concave collar for easy gripping. A rubber o-ring goes in between the rim and the collar to help seal the rim and match the contour of the rim profile. The valve core is removable so you can add sealant without removing your tire.

Tubeless Tape This is a required option.

One 10 yard roll of tape will be included. It is typically covers 2 rims with two laps each or 4 rims with one lap each.The high tensile tubeless tape features a natural rubber adhesive that does not leave a residue on the rims. On mountain bike rims, one layer of 18mm width tape is strong enough to seal the access holes which makes for the lightest tubeless setup.

INFO

TECH

WARRANTY

The WR38 was built with one goal in mind: making the best rim possible for long distance gravel racing or riding.

With a massive 25mm inner diameter, the WR38 provides a stable profile for even the widest gravel tires.

Thanks to its mid-depth profile, the WR38 is deep enough to provide aerodynamic help when riding alone across gravel plains, but not so deep that is hard to control in crosswinds.

Whether you find yourself racing across the Midwest or month long backpacking trip, the WR38 might just be the perfect match.

ExoTek: ExoTek-applied rims are designed to come out of the molds as a finished product which requires the most high quality manufacturing processes. The new resin system has superior consistency and forms the smoothest and most durable finish we’ve ever created. From a lengthened fatigue life to more robust interlaminar bonds, ExoTek raises the bar in performance and aesthetic.

EcoTek : Built from the highest grade of steel, we’ve engineered a completely new series of molds and developed a process that delivers a near flawless product. More time is taken through the layup and assembly process so that no post-production finishing is required. This new process is more environmentally friendly because it requires less heating cycles, no sanding, and no painting.

BlackTek : Rims featuring BlackTek come out of the molds as a finished product. Traditionally, rims are wet-sanded to remove imperfections like excess resin and then sprayed with a clearcoat. BlackTek rims come with a factory finish and the outer carbon layer is never disturbed after the curing cycle is completed. This is the most hard wearing and scratch resistant finish we have ever produced.

Flyweight: Our lightest construction method uses an exclusive unidirectional prepreg with a very low fiber areal weight. A variable thickness nipple bed reinforces key areas around the spoke holes, eliminating excess material. A blend of Toray T-700 and T-800 offers the weight saving benefits of T-800 carbon without compromising the strength or stiffness of the rim.

AeroTek: Our latest aerodynamic profile decreases lateral wind resistance and is both more stable and faster in a crosswind. A wider profile allows for larger and more efficient tires to be used without an aerodynamic penalty. Traditionally a tire can form a lightbulb shape when mounted on a narrow rim, but the airflow is much smoother with our wider rims.

Tubeless : All of our rims are tubeless compatible with bead seat retention. In most cases a floor pump is all that is needed to seal our rims. The bead shape is tailored to each rim width to achieve the best fit. Our hookless and clincher profiles have a smooth radius to reduce the chance of a pinch flat.

Wider: The wide profile offers improved aerodynamics, better handling in crosswinds condition and faster riding.

For Non-Pro Series Rims: From the date of purchase, 3-year Standard Warranty.

For Pro Series Rims: From the date of purchase, 5-year Pro Warranty as standard and an upgraded optional lifetime Premium Warranty with minimum charge.

Crash Replacement: It is applicable with the same period as the warranty time range that you purchased for the rims with 10% /25% discount for Non-Pro series /Pro series.

Mike : Yeah fitted them up with 38mm Panaracer GravelKing tyres. The width of the wheels works really well with the bigger tyres. I haven’t done a proper ride on them yet but can’t wait to.

COMMENTS

Jay 2020/01/08

Hello, I am interested in a wr38 based wheel set for my gravel bike. The wheels would be used for gravel racing. Would a flyweight rim with 24 spokes, cx-rays, be strong enough for the abuse of racing? I weight 65 kg and commonly wear a 5 kg hydration pack. Also, I see that the flyweight rims are only listed as a global option. Could they be sourced for the North American office to be built with i9 torch hubs? Thank you.

LightBicycle 2020/01/09

Hi Jay, 1. Sorry that you missed the Christmas sale. We do offer a 5% returning customer if you are interested. 2. What would be your idea wheel build this time? We do have DT Swiss hubs/I9/Onyx hubs for this wide road disc wheelset. Will you be interested? Thanks, Lightbicycle

Is the flyweight version suitable for my use? Using 28hole front/back hubs I weigh 86 kg Thanks

LightBicycle 2019/11/22

Hi Stan, The flyweight version of WR38 32mm wide road disc rims is okay for your weight, but we recommend the front flyweight and rear standard combo, which would be more durable. Thanks, Lightbicycle

Hi, On the WR38 disc, what is the maximum tyre pressure if running a 32mm tyre tubeless? Thanks, David

LightBicycle 2019/08/03

Hi David, For our WR38C road disc, the max tire pressure is 130psi recommended max. It is with hook design, can hold high tire pressure. Thanks, Lightbicycle

I would also like a hookless version of this rim. I am riding 40mm tyres at 35 psi

LightBicycle 2019/07/19

Hi Gavin, Currently, we only have hook version for road wide disc rim WR38 rims. If you like, we can make hookless version for you. It takes around 30 days, it is okay for you. Thanks, Lightbicycle

Is this rim available hookless? That would be preferred for a tubeless application.

LightBicycle 2019/06/25

HI Tyler, The hookless version of WR38 wide road 700C rim is currently not available. What is the reason that you want it to be hookless? How much tire pressure are you running with? What would be the target riding style? Thanks, Lightbicycle

Hi, Do these rims have a braking surface for rim brakes? Thanks

LightBicycle 2019/05/05

Hi Elliot, It is okay to manufacture these rims with rim brake. But is your bike and brake caliper wide enough for 32mm wide wheelset? Thanks, Lightbicycle

Do you stock these in the North America warehouse? If not, what is the lead time to get them? Thanks, Brian

LightBicycle 2019/05/08

Hi Brian, We don't have the Falcon Pro WR38 road wide bike rim stock in North America warehouse just yet. It would be faster if you order from the Global warehouse. Usually, the rims would take about 1~2 weeks to ship. another 7~10 days for shipping and delivery. Thanks, Lightbicycle

Érico 2019/04/28

Any chance they can be made for rim brake too? Do you have any plans of releasing a deeper version of the 30x56? Something like 80x30mm?

LightBicycle 2019/04/29

Hi Erico, What kind of riding do you do? Is it for non disc? The all-new WR38 road rim is with a wider section than normal non-disc rims. It's 25mm inner and 32mm outer. Will this be ok with your frame and caliper? Usually, calipers have limitation for the rim width. For deeper verson coming soon, it is 50mm deep, not 80mm deep. Is it okay for you? Thanks, Lightbicycle

Fred 2019/04/27

1) Will this work with tubeless tires? 2) Are you planning to release Falcom Pro rims in other depths? What about new tubular rims? Thank you! I'm ready to place North American order after these questions.

LightBicycle 2019/04/27

Hi Fred, Thanks for your inquiry! Yes, these new falcon pro wide road disc rims are okay for tubeless tires. You can use rim tape, sealant and tubeless tires. They will work perfectly. For falcon pro series, another 50mm depth will be ready in one week on website. For tubular version, how much tire width do you use? i will check with our engineer team. Thanks, Lightbicycle
