I am getting ready to order new sprockets and a chain. Keeping factory gearing. What brand sprockets have you had the best luck with? Rubber damper on front or no? Staying with 525 chain...I ride through sand everyday, so looking for something that holds up better than factory for the chain. I clean and lube the chain once a week or more when it rains. Bike is used to commute about 1k/month.
