Finish This is a required option.

Paintless: The "Finish" relates to how the rim is coated or painted such as matte or glossy for the most common applications. Our Recon Pro and Falcon Pro rims feature BlackTek and come out of molds as a completed product, with a scratch resistant and near flawless finish, eliminating the need for coating or painting. We name this kind of superior finish the paintless.

Crystal Painting: A fantastic painting effect designed by Light Bicycle.

Full Custom: This option offers custom finish such as Satin/Raw etc at no extra charge but subject to rim models with 3~5 days LONGER on manufacture. And custom color painting is also available with added 15g/rim and extra $20USD/rim as a start. If you select this option and LEAVE YOUR REQUIREMENT IN QUOTES IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed to finalize the details.

Rim Warranty This is a required option.

For Recon Pro Series ( MTB rim), Falcon Pro (road rim) and Drift Pro (fatbike rim), 5-year warranty is set as standard, and optional Lifetime Premium Warranty are kindly offered to purchase with minimum charge respectively.

5 Years

Lifetime USD +100/rim

Center Channel Hole This is a required option.

With Access Holes: This is the traditional method. Spoke access 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.

No Access Holes: No spoke access 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.

Currently, rims with 'No Access Holes' do not work with our carbon spokes.

With Access Holes

No Access Holes

Drain Hole This is a required option.

The two small drain holes located 90° to the valve hole effectively help evacuate both the water trapped inside the rim and the air leaking into the rim chamber caused by nonperfect tubeless tape sealing handwork that may risk rim explosure in an aggressive tire inflating.

It is the small reinforced layer prelaminated on the area where the drain hole is drilled later that makes the rim strength fairly ensured without any compromise of weight added.

Riders who ride in wet areas are suggested to order rims with drain holes.
More info about holes >>

With Drain Holes

No Drain Holes

Decal This is a required option.

1. Grey Laser Engraving (Falcon Pro) - Our laser engraving technology is eco-friendly and adds a snappy, polished aesthetic to your new rims.
Please note: Contrary to rims with any coated/painted finishes (matte, glossy and satin) as well as Crystal Painting, laser engraving could work with paintless rims only.

2. Full Custom - Add some additional personalization and go full custom with your rim graphics! Laser engraving is available in one colour (light grey) and starts at $5 USD per rim. If you select this option, LEAVE YOUR REQUEST IN QUOTES IN THE NOTES AT CHECKOUT. For example: "I need my personalized logo printed" or "Just text 'ABC racing' ". We will reach out to you once the order is placed to finalize the details of custom graphics.

Full Custom (Laser only) USD +5

Grey Laser Engraving (Falcon Pro)

Blank (No decal)

Valve Stem This is a required option.

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.

Information of tubeless rim tape

Apply Tubeless Tape: In Light Bicycle, a proprietary taping aid works with our wheel builders to guarantee that a solid taping craft at industrial-level is well implemented in order for you to ride carefree tubeless at any conditions.

You do NOT have to use any tubeless tape to run tubeless if you have chosen "No Access Holes" on the rim center channel.

Overview

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.

COMMENTS

Dave 2020/02/28

Can you please tell me why the WR38 disc (Standard) rim is $239 and the WR35 disc (Standard) rim is only $179? Why the big price difference? Thanks.

LightBicycle 2020/02/29

Hi Dave, The WR38 (32mm wide, 38mm deep) disc rim is from our Falcon Pro series, which is produced with a totally different technology and process (from the material, layup to molding). The WR38 is able to come out of the mold as a finished product. No post-production (painting, sanding, etc) applied what so ever. The scratch resistance ability is significantly increased. The rim is also stronger than traditional rims. On the other hand, WR35 (32mm wide, 35mm deep) is from our Falcon series, in which the rims are made with the traditional processes. It's also very strong, durable, lightweight, and the price is more friendly. If you are not a heavy/aggressive rider, the WR35 will be a good choice. Thanks, Lightbicycle

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

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

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
