Does your frame have horizontal rear dropouts - if so, install a chain tug such as the Surly Tuggnut http://surlybikes.com/parts/tuggnut - there are several options on the market.

 

Then mess with the tension so that your chain only has about 1/8 to 1/4 inch of play.

 

You might also want to install a chainwatcher on your seattube to help prevent it falling off the chainrings. K-Edge and Paul make expensive ones... but I just use the Third Eye which costs like 10 bucks. Ugly but functional.

 

If you don't have a horizontal dropout then you need a chain tensioner or an eccentric hub. IMHO, chain tensioners are crap for CX racing.

 

Finally, this magazine ran a good story about SSCX rigs in one of its early issues. You should search that out.

thanks...if I go with a chain ring guard, do I order the same size as my chain ring (36t) or something bigger?
