I have a CX bike that I mostly use for commuting, so about 500km per month. The bike has SRAM Rival 1x11 and has up to now been very quiet with smooth gear changes.

I don't ride in the rain or on very wet roads, and have so far limited my maintenance to to squirting on some some "Rock 'n Roll" wet lube on the cassette & chain every 3-4 weeks.

I've started to noticed that the drive chain is no longer as quiet as it was and there is just the slightest hesitation in shifting to the next rear cog on some gear changes.

It this a sign that I should completely degrease and clean the chain, cassette & RD cogs and re-lube?

Once clean, what is a reasonable frequency for applying wet or dry lube for my average usage (up to 500km per month)?

Another possibility is shifter cable wear, but the bike is only 5 months old, so I would hope this isn't the case!


Thanks for any advice!
