Hole Count This is a required option.

Please note that our valves are drilled for presta and spoke holes are made for external nipples by default.

Full Custom: This option (if provided here to choose) offers custom drilling for any other hole counts or special drilling (e.g G3/ 2:1 etc), most of which are at no extra charge. If you select this option and LEAVE YOUR TAILORED REQUIREMENT IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed.

Finish This is a required option.

Matte is slightly lighter and a more subtle finish (most popular). Glossy has a shine to it.

Full Custom: This option (if provided here to choose) 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 TAILORED REQUIREMENT IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed.

Weave This is a required option.

The layup schedule is predetermined for each model, but you can choose the outer layer for cosmetic appearence.

The rim strength & weight is virtually identical.

Matte UD is the most popular and has a subtle look.

The futuristic Hexa-Comb and Braided UD are smooth and looks great on deep rims.
More info about Weave >>

Full Custom: This option (if provided here to choose) offers custom weaves such as 3k twill vertical/ horizontal/ Braided UD etc with extra charge of $15USD/rim as a start but subject to rim models with 3~5 days LONGER on manufacture. If you select this option and LEAVE YOUR TAILORED REQUIREMENT IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed.

12K

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.

With Drain Holes

No Drain Holes

Decal This is a required option.

The new graphics are included and available in 7 colors. The decals are now easily replaceable so you can keep your rims looking fresh.

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.

Add Valve Stem USD +7 each

Tubeless Tape This is a required option.

Add Tubeless Tape: A roll of 10-yard-long tape is provided separately as parts to do the favor for those who treasure the dirt in the hand and are passionate in DIY stuff.
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.

COMMENTS

Austin 2021/03/19

What are the differences between the the AM431 and EN431?

LightBicycle 2021/03/19

Hi Austin, The EN431 is the reinforced version of AM431. If you consider yourself as an aggressive rider or heavy one, EN431 would be the better option for the rear 24" wheel. Thanks, Lightbicycle

Aleksandr 2021/03/06

Hello. What is the minimum pressure that can be used with hookless rims? I ride 35-40 pounds in my discipline with a lot of lateral pressure on the tire resulting in displacement. Will I have to constantly rip the tire off the rim without the hook?

LightBicycle 2021/03/06

Hi Aleksandr, For hookless rims, it is better to ride less than 40PSI to prevent from tires blowing off. The rims will be durable enough, we just worry the tires will blow off it is at higher tire pressure. What is your tire width? Thanks, Lightbicycle

Yaroslav 2020/09/13

Hi! I see that on the feature image it says AM431 400±15g. However just below in the table it says AM 430+/-15g, EN 480+/-15g Q1: why does weight for AM differ in the feature image and the table? Q2: what's the difference between AM and EN? Thanks,

LightBicycle 2020/09/14

Hi Sir, My apologies, it seems like an error on the "SPECS "section. The correct weight should be AM 400+/-15g, EN 450+/-15g. We already recover the correct data for this 24 inch bike rim. Sorry for the confusion. Thanks, Lightbicycle

Brett 2020/08/30

Greetings! I realise in this day and age that carbon tubeless rims are the number 1 choice for mountain bikers. Standards and wheel sizing is constantly changing. That having been said, I am seeking advice for a possibly one-off request for a set of carbon tubeless-ready rims – below are the specs: • 24" diameter • disc brake (no rim braking needed) • 32 standard spoke holes • 65mm external width • anywhere from 55 – 60mm (or more) internal width (whatever is possible) • Presta valved tubeless-ready (obviously) I understand that this is an unusual sized rim request, but I am really really really tied to my Surly 1x1 11th Anniversary Edition "sort of fat" fully-rigid 4130 chromoly steel bike, which I have ridden over 10,000 miles on since I purchased brand new back in 2010. Well, it has IMMENSELY heavy steel rims which are easily almost two pounds each. They have never caused me any problems, but they are simply impossible to set up tubelessly, and there is a lot of rotating mass to deal with. I have two sets of wheels with very nice carbon rims I purchased from Nextie Bike a few years ago, with over 10,000 miles on both sets of wheels and never had ANY problems. Nextie used to offer the 24" x 2.5" carbon tubeless rims but it seems as though they do not offer them anymore. Please let me know if it would be possible to have a set (2 rims) made, and obviously am curious how much this might cost since it would most likely be a one-off request. I thank you for your time. I am eagerly looking forward to your response. Thanks Brett Kelley

Hi Brett, Are you looking for 24" fat bike rim? Thanks, Lightbicycle
