RIM SPECS

Size 29er
Use Cross Country
Type Hookless
Tubeless Ready
Inner/Outer Width 23mm/28mm
Depth 23mm
ERD 593mm (not including nipple head dimension)
Weight 370+/-15g
Offset 2.6mm (asymmetric)
Weight Limit 105kg
Spoke Hole Angle ±5°
Spoke Tension ≤145kgf recommended
Tyre Pressure 20-40psi recommended
Tire 1.9" ~ 2.4" recommended

The rims use an easy to set up tubeless system complete with bead retention that still allows for quick tire changes. Of course you can still use tubes as required.

From all day epics and marathon events to hard charging short track XC racing, these wheels have a huge performance edge over wheelsets in this weight and price category. To achieve this kind of weight with an alloy wheelset, you have to make sacrifices to rim strength or width, stiffness, and build strength.

Scott 2018/09/08

Guys I’m after some rims for cyclocross. Do you have any rims for that type of cycling?

Michael 2018/03/19

Hi, I want to make some changes to my MTB (Scott Scale 920) so it loses some weight. My first change would be the wheel set . I am considering the XC923 rims. Do you think this is a good option? or what other rims would you suggest? I am 79kg. Thanks

LightBicycle 2018/03/20

Hi Mike, Are you going to use the same 2.2" tires? What kind of riding you do? Are you an aggressive rider? I want to know more details so I can provide a more suitable recommendation mtb 29er rims for you. Thanks, Lightbicycle

Corran 2018/03/01

Hi, I am looking for light 29er rims for cross country racing only. What wheels would you recommend? I am 51kg. Also, if I order some rims, how long will it take to be delivered to the UK? Thanks, Corran

LightBicycle 2018/03/02

Hi Corran, Building on your request, I have two rims for you. XC923 (2.6mm offset) and RM29C06 flyweight version. Here are the comparison and quotation for your ref. Thanks, Lightbicycle

Simon 2018/01/08

Hello, I am a cross country like rider - 61kg. I ride rocky trail with enduro like trails - I am not an agressive rider, but the trails are. What rims do you suggest between XC923 and RM29C19 ? Regards Simon

LightBicycle 2018/01/08

Hello Simon, Thanks for your inquiry. According to your info, I think you can go with RM29C19. This one is a bit stronger than the XC923 and the weight is very similar. It is also slightly wider which will help with more air volume (comfort) for long distance races. Thanks, Lightbicycle

Michael 2017/11/21

Hello All, I have two questions. Do you think the XC923 or RM29C06 would be okay running a 33mm CX tire? How strong are the Flyweight rims? Can they still handle Condition 3 mountain bike riding/racing? Thank you for the help! Michael Ybaben Portland, OR

LightBicycle 2017/11/21

Hi Michael, 1. We recommend our XC923 to run 1.9"~2.4" tire, and RM29C06 to run 1.9"~2.3" tire. 2. The max weight limit of our RM29C06(flyweight) is 100kg, which is suitable for non-aggressively riding and normal weight riders. May I know your weight please? Then we can check if it's strong enough for you. Thanks, Lightbicycle

Hello There are also the xc923 as flyweight. Regards Kai

LightBicycle 2017/07/20

Hi Kai, Thanks for your massage! Currently, we have no XC923 rims with flyweight version. So far, we have flyweight RM29C06 rims(280 /-15g). Is it okay for you? Thanks, Lightbicycle

Thank you for my wheels! They're beautiful, well built and light weight. Do you provide replacement decals? The ones I ordered and received are not as compatible with my overall color scheme as I had planned (metallic orange would be unbelievably perfect). Thanks Rob

LightBicycle 2017/05/15

Hello Rob, Happy to hear that you like our wheels. Thanks for your support. Yes, our newest stickers are easily replaceable. For orange sticker, only the attached one is available. Or would you like to replace the stickers in other color? Thanks, Lightbicycle

Stephen 2017/05/06

Hello What is the spoke length required to build the XC923 rims with the following hubs: Front - Cannondale Lefty 2.0 (32H) Rear - DT Swiss 350 (32H), 6 bolt Spokes - J bend (DT Comp) Nipples - Brass (DT Pro) Regards Stephen

LightBicycle 2017/05/08

Hello Stephen, Due to the complexity and variations with calculating spoke lengths, we cannot guarantee the spokes will be the perfect length for your wheels. For this reason it is best to confirm the spokes length with your own builder. If you like us to calculate the spokes length for your reference, please let us know the following details. Thank you. -XC923 rim with external nipple hole or internal nipple hole? -The rear wheel building is with 6mm offset or normal building? - Do you have a spoke lacing preference? 2-cross or 3-Cross? -the rear hub axle size -the nipple length Thanks, Lightbicycle

ESF 2017/01/11

Is there a rider weight limit for these rims?

LightBicycle 2017/01/12

Hello ESF, Thanks for your inquiry. The max weight for XC923 rim is 105kg. But it is an approximate estimate. May I know what your weight is? What is your riding terrain normally? Do you ride aggressively? Thanks, Lightbicycle

Davis 2016/10/04

I would like to lace these to my existing sunringle pro sl hubs. Do you provide a way to calculate or can you tell me the proper spoke length for use with your LB rim when I order? I will need 28 hole rim.

Light-Bicycle 2016/10/10

Hello Davis, Sorry for the late reply. We were on National Day vacation during Oct 1st ~ 7th. Regarding spokes length, it will be great if you confirm with your own builder. Because different builders and lacing pattern will use different spokes length. Or please let us know the following and we will calculate the spoke length for your reference. • Hub manufacturer name and model • Hub size as attached picture showed • Front and rear axle width • Straight pull or J-bend? • If you are using nipples with larger heads (double square, Squorx, or hex head for example), then we need to know this as the spokes are 1-2mm longer. Thanks, Light-bicycle

Marcus 2016/09/09

Hi, Do you have a single speed 142x12 hub option available for builds? In which brands do you stock them, Hope Pro 4, CK, DT preferred. Cheers, Marcus

Light-Bicycle 2016/09/09

Hello Marcus, Thanks for your inquiry. Currently, only Hope pro4 32H rear 135mm single speed is available, not Hope 12*142mm single speed hub or DT single speed hub. Does that work for you? Thanks, Light-bicycle

Hi, I just received 4 rims from you guys (they look amazing, especially the custom graphics - thanks!!!) and wondered if you could help me with spoke lengths, please? I need to build up 4 wheels as follows: 1) Lefty 1.0 front hub / 3 cross, 32 hole / 29er XC923 rim 2) Lefty 2.0 front hub / 3 cross, 32 hole / 29er RM29C06 3) DT 240s Rear hub / 3 cross, 32 hole / 29er XC293 rim 4) DT 240s Rear hub / 3 cross, 32 hole / 29er RM29C06 If you could give me an idea of the spoke lengths I'd need, that would be brilliant, many thanks and keep up the great work. Jim

Light-Bicycle 2016/09/02

Hello Jim, Happy to hear that you like our rims. Please let us know the following and we can calculate the spoke length for your reference.

Is it possible to get 2 of the lightest rims sorted out to get some rims close to the 355 g (370 g - 15 g)? What is usually the lightest weight of the XC923 then?

Light-Bicycle 2016/07/29

Hello TR, Thanks for your inquiry. I checked our order system, and the lightest rims in stock currently are as below. XC923, 32H: 367g & 372g XC923, 28H: 380g & 381g Is it okay for you? Thanks, Light-bicycle.

Aloysius 2016/07/07

I ride most XC and occasional light trails. I am considering between the RM29C06 and XC923. Which is better and why? Also there is a big difference in price between the two. Is it only because the XC923 is newer?

Light-Bicycle 2016/07/08

Hi Aloysius, RM29C06 and XC923: • Both rims feature angled spoke holes, a modern u-shaped profile, have a bead lock and work with or without tubes. • Our XC923 asymmetrical rims will have more even spoke tension than our RM29C06 which results in a more durable wheel build. The low tension spokes will be at higher tension compared to a traditional rim which results in less wheel re-truing. • Both rims come with a 1-year warranty. The XC923 rims have a 2-year crash replacement policy at 25% discount, and the RM29C06 have a 1-year crash replacement policy at 15% discount. • For asymmetric rims, they are manufactured by our leading workers in the production line. We have set up a special production line for asymmetric rims only. All the workers on this production line are the best in our factory. Thanks, Light-bicycle
