Can I run an oval or elliptical chainring with my chainguide?

While it is technically possible to run an oval or elliptical chainring with your TRS or LG1 Chainguide the chain retention capability of the guide is diminished. This is is due to the gap which opens at the slider location as the narrow part of the ring passes thru the slider. 

One should also note the max ring capacity of the chainguide will not be the same as when running a round ring. A guide with a 34t max capacity may only be able to accomodate a 30 or 32 tooth ring depending on the profile of the ring.

I got a new frame with a different ISCG standard, can I replace just the backplate of my current guide rather than the whole thing?

For most of our guides the backplate is the bulk of the cost of the guide, so we don't offer replacement backplates for all guides. Check your guide's service parts diagram to see if backplates are available for your guide. In some cases it may make sense to get a new complete guide.
