Hi Sir, Our rims are predrilled professionally and rim spoke wall thickness is strong enough. No need to use nipple washers in wheel buildings at the standard procedure. Thanks, Lightbicycle

Hi Jakob, So good to know that your WR29C06 still works well since 2017. The rim brake surface special material and resin system supposes to put on the rim before molding. You can not use a disc rims on a rim brake now. There is not special brake surface on these mtb bike wheels. So my suggestion is, buy a new set of wheels that made with rim brake. It would also take a lot of effort to convert a rim brake bike to a disc brake bike as well. So buying a new set would be the best option. Thanks, Lightbicycle

Hi Tom, The flyweight version of 29er XC rim RM29C06 (27mm wide) is USD158 (UD, matte, 32H) each. For the flyweight version, our recommendation usage would be for the front wheel of a CX bike (or gravel bike). I would also have to point out that the rider weight limit of this particular rim is 90kg. If you are heavier than 90kg or riding a bit aggressive, the rim won't be a good choice. Normally, we recommend using the flyweight version for the front wheel and the standard version for the rear wheel. Riding with 55psi is totally ok for rim RM29C06 as our recommendation tire pressure is under 60psi. Max spoke tension is 135KGF. Please do not exceed 135kgf while wheel building. We also email you the spoke tension chat we normal use for your reference. Thanks, Lightbicycle

Hi Tchell, Since you are not doing aggressive riding and not a heavy rider yourself, we recommend using the flyweight version on the front and the standard version on the back. Are you looking for building a complete 29er XC wheelset from us? or carbon fiber bike rims only? Thanks, Lightbicycle

Hi Chris, Few questions for you before you place the order. Let me learn more about your riding condition to make the proper recommendation. 1. What is the tire width you use? The recommended tire width for RM29C06 is 2.0~2.2". 2. Are you an aggressive rider? You are not a big guy, so as long as you don't ride aggressively, The flyweight is ok. 3. Do you ride rocky terrain often? Then we can check whether flyweight version 29er mtb bike rim is strong enough for you. Thanks, Lightbicycle

Hi sir, RM29C06 flyweight version is for light XC riding. Could you kindly tell me what kind of riding you do? Are you an aggressive rider? I need more info to tell whether the flyweight version is right for you. Thanks, Lightbicycle

Hi Roger, 40psi is the tire pressure we recommend to you that keep tire safely on the rim and make sure your rims at their best performance during riding. Normally, nobody would ride over 40psi during riding. 70psi is the tire pressure we used on lab when testing the rim mounted with an inflated tire. 70psi is the max tire pressure. We highly NOT recommend run with high pressure. Thanks, Lightbicycle

Hi sir, What kind of riding style will you ride on RM29C06 rims? Do you ride aggressively? Normally, RM29C06 flyweight is for racing only. While normal training, it is better to use standard version for daily training. Thanks, Lightbicycle

If you like to place the order through our website, you can leave a massage that “you like rims without decals” when you place the order. Then we will see it and send you the plain rims. When you checkout, there is a message box for leaving message. Thanks, Lightbicycle

Hi Kevin, Thanks for you inquiry! Currently, we do not have this rim in hook version. Do you ride road or road disc? May I know your tire width and your weight please? What about your usually tire pressure? Then we can check which is the suitable and lightest rim for you. We have RG922 hook(29mm outer/22mm inner). It should be okay for you. Thanks, Lightbicycle

Hi Rob, Sorry for the late reply. We were on National Day vacation from October 1st to 7th. We are just back to work today. How much tire pressure will you use? Then we can check whether RM29C06 rim is okay or not for your cyclocross riding. It is hookless design, it is better to make sure the tire pressure is less than 40 psi while riding, to preventing from tire blowing out while riding. Please check our RG922 gravel rim profile as attached. It is 29mm wide and 28mm deep, with hook design. It can hold tire pressure that is higher than 100psi. Thanks, Lightbicycle
