Greets!

Have an issue and hope someone can help me out. I got a Fit Flow Street, running 30 front with a 11 tooth drive in the back. I got the bike used but in great shape off CraigsList. Anyway... Two things are happening. Sometimes when I pedal hard I will hear a "POP" but nothing else happens. Other times I will hear another not as loud "POP" and it feels like it slips. It seems to be coming from the driver but I am not 100% sure. I had a standard chain on it and now have gone to a Shadow half link 2.

I have wanted to get a new driver ever since I heard the one on the Mirraco Blend LTD that is loud as ****. Do you think replacing it will do the trick or could it be something else?

PS I have no idea what kind of driver is on it right now.

Thanks in advance for any help.

Well, I dont know anything about anything but I do know that this is a pretty sweet pic. I'm pretty sure I can actually see you reflecting off the bike. Blue jeans white shirt. Haha, thats all I had to say.

That half link chain is crazy! I've never seen that before.

What the hell is the driver? The front chain ring?

Driver is the rear cog that inserts into the hub. My hub does this every so often to (and it's getting more frequent that the hub is getting older, it's an Odyssey Hazardlite). I recommend just taking your driver off, cleaning it and re-lubing it. It seems to help mine a bit.

Also, your chain is on wrong, it should be like this:

Don't get anything Mirraco, they have enough problems on their own without customers.


Your driver might have broken springs/pawls in it, take it to a shop to have it checked out. Some hubs just skip every once in awhile, Odyssey is well known for that.

The driver I wanted to get is made by SNAFU, its just on the Mirraco bike. Any thoughts? Any other recommendations for a loud driver?

I'd say Shadow, but I know better. Primo.

Get an odyssey, or kink driver. The hub is identical to the odyssey cassette without the odyssey logo on it. Anything that is compatible with odyssey's hub will work.

Cog, or freewheel? I've always just called them singlespeed or BMX freewheels. BMX terminology must be a bit different from road bike terminology. I'll have to research some of that.

FuzzyRyder

It's a driver. Basically a one piece driver/cog unit for a cassette hub.

hockeyteeth

When I hear cassette hub, I think splined freewheel with a cassette of cogs held in place by a lockring. The BMX driver is simply a freewheel screwed on to a hub, no?

KinetikBiker

I have a feeling you are talking about sprockets, not drivers.

FuzzyRyder

Cassette drivers just slide into place and are held in by a nut on the outside. a traditional cog an driver is the same, but the cog slides on sepaeratly and is held in place by a lock ring.

felixpdx

This is what I am calling the "driver". Am I using the wrong terminology? Could this make it POP and slip?



Thanks.

Damn, BMX components have gotten a lot nicer.

FitRider 921

Yep.

FuzzyRyder

Yes that is the driver. The problem could just be the pawls are worn out and slipping, or some of the springs may not be working. You can replace the pawls and springs, but I'd just buy a new driver.

cwt341

yea my bike does the same thing and sometimes it scares me because i dont know like if the chain is gonna come off or what not

sprintcarblue

thats the problem with any cassettes, once they get worn in they kind of go down hill. My odyssey cassettes have always gotten pretty grotesqe sounding before I do something about it. My geisha has been amazing, though, thusfar.

PS, i think on occasion is normal since sometimes the pawls dont quite get in the right spot before you pedal, so it catches a tad and when you pedal it slips to the next slot. If it is more frequent you just need to replace the pawls and springs.

PPS, If you want it to be loud, just remove the normal grease and put in a real light-weight grease inthere instead.

Think of it as a cassette, with only one cog. No more exploding freewheels. To change gearing, we can replace the cog just like a cassette.

Brain,

I have that same Haro 24 as well. Great bike!

Do fixed gear MTB's not use one piece drivers?

hockeyteeth

You mean single speed? I've seen SS MTBs converted using a multi-speed cassette and spacers on either side of the desired cog. You can also thread a ****ty single speed freewheel (like the one I posted a picture of above) onto an older hub or one of the newer flip flop hubs. Fixed Gear MTBs would use a track hub with a cog and lock ring. Or you could thread a cog onto a freewheel hub and loc-tite a BB lockring onto the hub to secure the cog. But that's waaaay ghetto.
