Tube in a tubeless rim

Featured Replies

When you put a tube in a tubeless rim do you need a security bolt?

no, and theres probably no place to drill the hole, if you wanted to do that.

just make sure the tyre is well seated and the tube isnt nipped and you will be fine.

in theory you may loose some grip, in practice i doubt you'll notice unless you are very good and particularly well tuned to the bike/conditions.

I have got a front tubeless rim that I want to use (with a tube) - should I use tubed or tubeless tyre, and would I need a security bolt?
