Hi I am going to replace all the drive chain on my Fathom E+ pro 11 speed soon as the chain has reached .75 wear and do get a bit of skipping on the small cog.At present it has the Praxis Wavetm 36T Cold Forged 4130 which is still OK but would like to replace with a 38 tooth. What is a good replacement as well as a chain that will not cost the earth.The bike has only done 420 miles and hope to get more mileage out the next.I have always cleaned and lubed the chain but have ridden in mudy conditions a lot due to lots of rain here in the UK.
