One 10 yard roll of tape will be included.

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 XC745 (RM650BC15) will give you the smooth rolling traction you’ve always wanted.


Typically, stock alloy plus wheelsets 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 rims! 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.

Would it be possible to get a custom wheelset built with these rims laced to DT350 fat bike hubs?


LightBicycle 2018/10/31

Hi Kdubs, Yes, we can build this 650B wheelset with DT 350 fat bike hubs for you. Pls make sure you are using 2.8~3.1" tires to build the wheels. Thanks, Lightbicycle

Is there anyway to ask for the lighest weight of these rims to be used for a wheelset build. I am 110 lbs so do not want a heavy rim. 450g -455g is OK but would not want to get something 470-490g.


LightBicycle 2017/07/20

Hi Jill, Thanks for your inquiry! Okay, We will try our best to pick up the rims less than 460g for you. Does it work for you? Thanks, Lightbicycle

Hello, what is the spoke hole offset on the offset rims?

If I place my order can you please send me rims that weigh 430g or less? I'm willing to wait


Light-Bicycle 2016/11/02

Hello Ben, Thanks for your inquiry. RM650BC14 (50mm width): weight under 455g, $200/pcs I double checked with our engineer, and we only can manufacture the rims around 450g ~ 455g. If the rim at 430g, it is not strong enough for your riding and will affect the rims strength. Thanks, Light-bicycle

Hullo, is possible to buy two rims RM650 BC14, one rim with 24 holes and an other with 28 holes ? thank you very much Fabio


Light-Bicycle 2016/09/01

Hello Fabio, Thanks for your inquiry. It is okay to order 2pcs RM650BC14 in 24H/28H. For drilling pattern, center drilling as attached picture is more popular. Does that work for you? Thanks, Light-bicycle

Your 50 mm 29er rims are great with 3.0 tires on my krampus. I'm not sure why folks are unhappy with that width


Light-Bicycle 2016/05/27

Hello Sandy, Thanks for your support. We are so happy you are enjoying the rims. It would be great to see a picture of them on your bike! Happy Trails! Light-bicycle

I wish these were 40 ID. These rims are too wide for the optimal 2.8" plus tires.


Light-Bicycle 2016/05/26

Hello Matt, Thanks for your inquiry. Our 650B plus rim is with 50mm outer/ 45mm inner width. Don’t worry, it can work well with 2.8’’ tires. The recommend tires width are 2.8’’ – 3.1’’. Thanks, Light-bicycle

Nicol 2017/01/11

"650B plus rim is with 50mm outer/ 45mm inner width" -- is this the standard size for 650B plus?


LightBicycle 2017/01/12

Hello Nicol, Thanks for your inquiry. Yes, our 50mm wide 650B plus rim is the standard size. The recommend tires width are 2.8’’ ~ 3.1’’. Thanks, Lightbicycle

I am interested in the RM650BC14 but with a 40mm internal and 45mm outer. Can you tell me when / if this will be made? Thanks in advance Tony


Light-Bicycle 2016/05/19

Hello Tony, Thanks for your inquiry. Currently, only 40mm and 50mm outer width rims are available. Rims profile attached for reference. We will discuss with our engineers, and will let you know once we have a plan to make the 40mm internal and 45mm outer rim. Thanks, Light-bicycle

Cam 2016/07/08

Hi there, I would like to buy a 37-41 mm internal width 27.5 rim for my plus bike. The 45mm and 33mm internal rims are not ideal for 2.8" tires. When will you be coming out with such a rim? Keep up the good work! - Cam


Light-Bicycle 2016/07/09

Hello Cam, Thanks for your inquiry. Currently, we don't have the 37mm~41mm inner width rims. We might manufacture this kind of rim in the future. But it's hard to tell the availability of time frame. The most similar rims are 33.6mm inner rim(AM733) and 45mm inner(RM650BC14). Is it OK for you? AM733: 2.3''~3.1'' tires RM650BC14: 2.8''~3.1'' tires Thanks, Light-bicycle
