The free coaster has a clutch on the inside, so when the rider starts to pedal, the driver is turned. The process of this motion from the rider will cause the clutch to move towards the driver. In almost all coasters the clutch is made to not move forward with the driver by a spring inside the axel.
This spring plays a crucial role as its main objective is to ensure that the threads of the free coaster driver will pull the clutch in. When the clutch moves into position, it aligns to one of the many ridges on the clutch and the hub will begin to turn. When the clutch is in a ridge and the rider is pedalling, the BMX will propel forward due to the driver not being able to slip outside of the clutch.
This allows for the rider to ride the bike normally and leverage a free motion when the bike is not being pedalled. As the rider stops pedalling, the movement of the hub will then push out the clutch from the driver thread to disengage, leaving the driver to be left to glide over the threads as the hub and axel continues to move.
Some users complain about the slack on a free coaster and this is down to a rational gap in the clutch.
This is the slight movement between the driver hitting the closest ridge on the clutch. The reason why there is a greater amount of slack in because a normal cassette with take up to a 20th of a turn to engage, whereas a free coaster could take a 10th of a crank turn, thus causing a bigger delay in engagement.
As the wheels turn backwards, so will the cranks. This is a particularly easy way to understand the difference between a free coaster and a cassette. You want some slack in the crank before the hub engages You don't want to pedal backwards Bonus - You know enough about bikes that maintaining one won't be a hassle.
So with that, buy a cassette and go ride. Dude really I ride park and the year and a half I've been riding, I've ridden cassettes I first got my bike and it had a cassette and just rode it. My back wheel got loose not a great wheel anyway so I splurged and bought a Primo 7 series with a free coaster on it and had no idea there was a difference, a different name, etc.
I rode that for a few years. So don't get so distracted by what one website says, what options you think you might need. If nobody told you "This is different" or "This is better" you would never notice. BMX is very much a ride it and try it sport. You can't predict whether or not you'll like or hate a part or a specific arrangement.
What a Ride! If you're starting out, I'd go with a cassette. They're easier and make a little more sense when you're starting out plus the added pedal pressure control can help give you more confidence. Switch to a freecoaster once youre already rolling backwards. You really just have to try both for yourself to answer that question cuz everyone wants different things and the only way you'll find out what you like is by trying it personally.
Anthony Loves Subrosa. I learned how to ride on a freecoaster. I know i'm a freak. But I converted to cassette gang very recently. Just get cassette, less maintenance and more durable. Just get cassette, I also started on a coaster. I switched to a cassette eclat Dynamic v1 for a while and it tore itself to pieces due to shit seals, a driver bushing that was far too soft and ratchet ring teeth that were far too shallow. I found I was constantly maintaining it and bodging it back together.
After that completely shit the bed, I went straight back to a coaster and haven't missed the cassette once. My point is, not all cassettes are equal.
There's a few common misconceptions regarding coasters, they don't require any more maintenance than you should be doing to a cassette and if properly maintained, they're arguably more durable. You've made 2 threads on which hub to go with, but you still Sorry to reply to an old thread, but what do you mean by "maintaining one won't be a hassle"?
Unlike a freecoaster where you do not have to pedal backwards. Most of the noise comes from pawls on the freewheel hitting against the splines on the engagment surfaces which makes up the racheting unit. The reason this is desirable is that more pawls and engagement points means faster engagement when you start pedaling.
It is much easier to push with opposite leg quads and glutes to get the involved leg past the hump, rather than pull hamstrings and gastrocs. The fastest mile run backwards is 5 min Aaron is the head track and cross country coach at Bethany College in Lindsborg Kansas.
