Hiya,

New to the sport and have a recurring problem. I am riding a 29er hardtail and keep dropping my chain when riding on rougher terrain, usually downhill. It slaps about pretty hard as well.

I have looked up chain guides and the like, but note that they seem to work for one or two chain ring set ups, where I have 3. Also, I was wondering whether a chain tensioner might do the trick - or both.

I would appreciate any advice anyone has on what I can do equipment or set up wise to try and minimise this.
