We include enough valves to cover your individual rim purchase. We use a lightweight black alloy anodized valve 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 vavle core is removeable so you can add sealant withoutn 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.

With a huge 45mm internal width and the ability to run anything from a 2.8” tire right up to a monstrous 3.2”, the XC945 (RM29C15) will give you the smooth rolling traction you’ve always wanted.


Typically, stock alloy plus rims are built with heavier spokes to make up for their lack of stiffness. With a vertically compliant rim and significant side stiffness, lighter spokes are used to reduce overall wheel weight. Upgrading to our plus rims can easily save more than a pound off of a stock rim! Breath new life into your ride and bring a new level of responsiveness, stiffness, and control.

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.


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.

Hi there, What's the best spoke hole drilling pattern for a Rohloff hub? What diameter are the spoke holes? Rohloff recommend a minimum 4.4mm. Thanks, Geoff


LightBicycle 2018/07/05

Hi Geoff, May i have your hub specs link? And what spoke gauge do you use? Is it 13G or 14G? Then we can check which spoke hole diameter is good for you. Thanks, Lightbicycle

Alex 2018/04/04

Hi guys - for the 29-plus rim with offset drilling, how much adjustment do you recommend for spoke length to compensate for the offset? A typical non-plus design would add/subtract 1mm usually. Thanks!


LightBicycle 2018/04/05

Hi Alex, Thanks for your inquiry! For RM29C15 plus rim, the drilling offset is +/-4mm. Please find attached rim drawing. The spoke holes are drilling with offset+4mm and -4mm. Please let us know if there is any other questions. Thanks, Lightbicycle

LightBicycle 2017/10/14

Hi Jesse, Sorry for the delay reply! Currently, we only have DT 240s/350s and Hope hub in stock. If you like "100mm aluminum nimbus isis unicycle hub", can you send us the hub link for our reference? Then we can check if we can get the hub for you. May I know your tire width and your weight please? Then we can check which rim is better for you and quote accordingly. Do you just want a wheel for your unicycle? Thanks, Lightbicycle

Hello, I want to make a custom wheel with 18 holes with dual drilling pattern, so 36 total. Can you do this for me? Thanks, Jason


LightBicycle 2017/08/16

Hi Chris, Thanks for your massage! In order to calculate the spoke length more accurately, could you please offer more information about the hubs & nipples that you will use? And then we can give you the spoke length accordingly. Thanks, Lightbicycle

Jason 2017/02/22

Why are the center drilled holes not in a straight line? Do the hole locations make the wheel weaker or heavier?


LightBicycle 2017/02/23

Hello Jason, Thanks for your inquiry. The 50mm wide 29er plus rim is much wider, so the spoke holes are drilled with center drilling which allow for better balance of tensions in a wheel build, resulting in a stronger, stiffer, and more durable wheel. It won’t make the wheel heavier but make it more reliable. Thanks, Lightbicycle
