  1. Thanks for this Mark First time I’ve seen all the actual specs

    • You bet Blane. Thanks too for letting me know it helps you. Makes doing this worthwhile.

    • any videos to mounting o-ring chain?
      received my light b x w/added pedal kit and I’m wondering if i can remove the pedal kit and install the o ring chain included without much effort. two rides in and i want to leave the pegs for a while without spinning the pedal kit bb spindle needlessly.
      seems ideal, then if I want to mount the pedal kit again I go back to the standard chain.
      amazing work on your site! your build and comments on quality of the manufacturing were major reasons that led me to buy. Thank You!

      • Hi Adam and welcome to the Sur Ron addiction! LOL Changing over to an O ring chain is no different than your non O ringer. On my Specifications page you can see how many links are needed depending on your sprocket size. If you need to remove links on my Gear I Use page I have the chain breaker I use there along with the O ring Master Link I’ve purchased. Hope this helps you.

  2. 107 links 48T + pedal kit, this must be wrong, the chain can not have an odd number of links

    • Thank you for pointing this out Roger. I obtained the information from the online resource supported by Luna here. I have removed the pedal kit link count from my site. Once I actually count it myself I will repost the correct link count. Thanks again.

  3. Wow Mark. Last night I finally opened up the FAQ and bingo, up pops †he torque specs I’ve been trying to find for months. Not sure why several Luna staff I’ve asked seem to have no idea such a thing exists… another wonderful surprise from your good efforts… as always, thanks!

    • Glad you find the site and information helpful. Thanks for letting me know John. Take care
