    Weird thing happened on the way up to mountain - need smart mechanics to weigh in

    So I bought a Sette Razzo about a month ago. It's been a great bike and I am loving it. Today I was cranking up this long 11 mile uphill grind (my 6th ride since I got it) and I noticed something really odd. The bike comes with Formula DC 32 hubs which are pretty loud when you are coasting. Here's a video ( not mine Formula Hub Sound, DC-32 - YouTube ). So I notice at some point along the climb, that when I coast I am almost silent. I can hear my freewheel spinning but no more loud freewheel noise. Nothing else appears to be wrong with the bike, shifting is fine, cranking seems fine. After I noticed I had another 2 miles of climb and didn't notice any mechanical problems. The pedals weren't jumping, shifting, etc... At the top I ran in to a couple of downhillers who work on their own bikes, they looked it over and didn't have any advice.

    I know it's covered under warranty, but I don't know for sure there is anything wrong. Is it possible the hub just "broke in " and is quiet now? I was riding with headphones, so I can't say that something didn't pop along the way and I just didn't hear it. I'm pretty savvy and do my own maintenance, but this has me puzzled.

    Thanks in advance for any thoughts.

    @customfab Absolutely. Just wondered if anyone had any insight regarding this issue, maybe what I should be looking for, etc...

    I have contacted both Sette and PricePoint in the event it's a warranty issue.

    No, hubs don't get silent after "breaking in," although they may get quieter. The buzzing noise is from the spring-loaded pawls inside the freewheel as they rub against the teeth of the freehub, which provide the engagement when you pedal. The only way I can think of a wheel getting silent is if it's overhauled and heavy grease is used in re-assembly or if the springs get soft. You could've also broken a spring.

    As customfab stated, you should really pull it apart. Here's a generic how-to service freehubs as I wasn't able to find anything for your exact model:

    Thanks - the direction helps. I've been out of riding for 15 years, so some of the technology is new to me.

    Heard back from the company - they have this down as a known break-in issue and it will get quieter. So I will still pull it apart, but he thinks it's normal.

    We shall see.
