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.

The XC924 (RM29C19) rims blur the lines between XC race and All Mountain. The 24mm internal width can handle narrower 2.1” tires, but can also mount up to 2.4” with confidence when the trail conditions turn nasty. Whether attacking the climbs on technical XC courses on the weekend, or shredding the descents on your local trails mid-week, this rim is equally at home.


This high-value modern U-shaped profile has become one of our most popular rims for trail riders. Oversized hookless lips, bead seat bumps and a sensible sub-400 gram layup design keep things competitively light and reliable.

Hookless: Carbon fiber flows continuously over the bead area to provide the best impact resistance and a significant strength increase compared to a clincher rim.


Manufacturing process: Our air bladders are made from a special material which produces smoother walls, result in a lighter rim, and are completely removed without harsh chemicals. They are removed through the valve hole with a unique process so that the rim does not have to be patched like traditional manufacturers use. This significantly improves the strength of the rims. Read More about our process


T700: Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.


Precise layup: Each rim carries its own layup schedule documents which are followed meticulously by the layup workers. Our Engineering team creates a unique fiber orientation which amplifies the desired riding characteristics for a given rim.


Angled Holes: Angled spoke holes allows the nipple to pull straight in line with the spoke for reduced stress. This results in fewer broken spokes and nipples.


U-Shape: U-shape profile spreads the force of impacts and creates a more robust product.


Bead lock: The small ridges on either side of the drop channel help secure tubeless tires in place. The bead lock makes it easier to seal up tubeless tires with a floor pump, and they are incredibly hard to burp.


Tubeless: While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.


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.

Alastair 2018/11/17

Hello there. I just wanted to know what the difference is between the XC924 and the XC925 rim. I am planning on building my own Wheelset. I see one is 24mm and one is 25 as the obvious differences and the 925 is assymetric. What is the difference between a symmetrical and assymetric rim? And will there be a noticeable QUANTIFIABLE difference in ride between a 24mm and 25mm rim? I currently ride 24mm wide on my American Classic MTB RACE 29. But with American classic closing parts availability is a concern and leaves me with no way of upgrading my current wheels to chimano XTR microspline. I am 65KG. Cross country racer in South Africa. So I often ride sections of the Epic route. I do feel I am quite an aggressive rider and don't mind pointing my Hardtail down sections that would make AM riders a bit squeamish. I plan on mating these wheels to a Trek Procaliber. If I use DT swiss's spoke calculator using the ERD you specify 28H XC924's should come out at around 1437g using 240S CL boost hubs with DY aerolite SPOKES. A tiny bit heavier if I use XTR M9110 hubs. XC925's in 28H but not flyweight (scared of breaking something if I go TOO light) come in at the same configuration as the above at around 1367g according to the DT calculations. Putting aero comps in the rear wheel puts it to 1407g. Now what would the difference be between the 924 and 925? Also should I build the rear as a 32H for a bit of extra durability or keep 28H but use stronger spokes for the rear like DT Aero Comp? I am trying to keep costs down though. Using the parts I've chosen the 924s woukd come in at around 11500 ZAR (820 USD) The 925s would be around 14000ZAR or bang on 1K USD +-. 925USD if I put aero comps on the rear wheel. So is there a significant difference between the 924 and 925? Also do you ship to South Africa?


LightBicycle 2018/11/20

Hi Alastair, XC925 29er rims belongs to our Recon Pro rims which use a completely new mold design and new manufacturing process that allows the rims to come out of the mold as a finished product (no sanding & painting needed). The rims come out from mold perfectly directly, without any defect to affect strength. The layers of carbon are not disturbed post-production which results in a stronger rim with a more scratch resistant finish. We use a new resin system with a lengthened fatigue life and superior consistency. The new recon pro rims are more durable and made in new dust-free production line. All of these improvements coupled with an updated asymmetric profile shape has allowed us to extend our standard warranty on these rims to 3 years with an upgrade option to 5 full years! Thanks, Lightbicycle

Hi Can you make the hole for schrader valve?


LightBicycle 2018/09/12

Hi Avner, The rims are manufactured with presta valve hole by default, the valve hole size is 8mm upper/ 6.5mm lower. If you like schrader valve hole size, you can leave an message on the order. Then we can manufacture the valve hole size to be 8.5mm for both upper & lower. Thanks, Lightbicycle

Paul 2018/07/27

Hello! I'm building a set of wheels for a 29er hardtail. Front will have a 28H predictive hub for an RS1 fork. The rear will have a 32H Hope Pro Evo 2 hub. I'm 80kg and ride non-technical XC. I'm thinking the RM29C19 would be best? Thanks, Paul.


LightBicycle 2018/07/27

Hi Paul, We sent this 29er wheelset quotation to your email. Have you got it? May i know your weight and tire width? Then we can check whether this wheelset is the best for you. Thanks, Lightbicycle

Can you make these rim deeper around 40mm or more? Looking for a 29er or 700c rim that is about 24-25mm wide internal and 30-32mm external wide that is deep so I can use on my gravel bike. Thank you!


LightBicycle 2018/02/07

Hi John, Sorry to tell you that we don't have 29er or 700C rim with 40mm deep or deeper rims. But, we do have RG922 that specially designed for gravel. It's with asymmetric design. Thanks, Lightbicycle

Vern 2017/12/14

I am right at the weight limit of 120 kg. Can your rims be made for larger riders?


LightBicycle 2017/12/15

Hi Vern, We can add some carbon fiber to enhance the RM29C19 rim’s strength, with a heavier weight about 50g. We also have some wider rim like 34mm/35mm/38mm width for large riders. May I know what your riding terrain is normally? Do you ride aggressively? What the tire width you use? Then we will do some recommendations accordingly. Thanks, Lightbicycle

Eddie 2017/04/14

Can these rims be laced to industry nine staight pull spoke hubs? They have proprietary spokes that need a slightly larger hole drilled through the rim bed. What is the diameter of the hole drilled through the rim where the rim tape is applied?


LightBicycle 2017/04/14

Hello Eddie, Thanks for your support. Yes, our rims work with I9 hubs and spokes. Will you build the wheels by yourself or take it to your local bike shop for wheels building? Currently, The spoke hole on the rim bed is 8mm. Does that work for you? Thanks, Lightbicycle

Flo 2017/01/20

Hello, I'm a 65kg XC Racer. Which Rims would you recommend for me? Is it possiple to get a lighter example/version? I would use them in 29" and with Boost Hubs, do asymetrical Rims make sense with boost hubs? Thanks, Florian


LightBicycle 2017/01/21

Hello Florian, Thanks for your inquiry. According to your info, we’d like to recommend our 28mm wide 29er asymmetric light rims. It is designed for XC racing and strong enough for your riding. Also, the rim will work with the boost hubs. Thanks, Lightbicycle

Chuck 2017/01/14

Have a Giant mtn bike ,would love to up grade those rims.So if i buy these Rm29c19 will fit ?Do i just respoke these wheels with my hubs and spokes?


LightBicycle 2017/01/16

Hello Chuck, Thanks for your inquiry. For spokes, may I know your rim ERD? Then we will check if you can reuse your spokes. Normally, you need to get some new spokes, because the rim ERD is different, so the spoke length will be different. Our RM29C19 rim ERD is 589mm (not including nipple head dimension). Thanks, Lightbicycle

Hi, is the price quoted for RM29C19 $173 per one wheel or the set of two? Also, what would be estimated time from placing an order to delivery of just the rims versus fully built wheels? Thanks TS


LightBicycle 2016/11/22

Hello Tomek, Thanks for your inquiry. The RM29C19 rim is $170/pcs. The price is for single rim only. The delivery cost is $50 for two rims to USA by EMS. All pricing in USD. We have several UD matte 32H rims ready for ship and will ship within 2 business days. EMS delivery takes another 4-7 days to arrive. Thanks, Lightbicycle
