I want to replace the rubber pineapple on my Schwinn Point beach cruiser with a quality sprocket hub adapter. I've looked it up on the thread search and most are about CB hubs. I need one for the type of rim shown. I've looked on SBP Venicemotorbike.Com and gasbike.net and am not for sure what to do. Any help will be appreciated thank.

These are fairly easy to install and I got one installed on my stingray wheel, much easier to install than the common rag joint that comes in the kits... just slip the 2 halves over the hub thru the spokes a d torque down just snug at first, install the sprocket and tighten just snug, you want it just loose enough to be able to slide it on the hub to set the chain alignment,then once you got it incline with the engine sprocket, just go back and torque everything down and you're done... much much easier than installing and setting up a rag joint, just be sure you get the right size to match your hub... you can measure your hub diameter with a set of calipers before you order.
most of these are pretty much the same and most the sprockets made for these have the same 3 hole pattern so its also easy finding sprockets from the same or different vendors. I got mine from pedalchopper's site but the stingray is a kind of unique size.

That measurement must be precise. Down to the thousands of an inch. Almost, or close enough, won't hack it with a hub adapter. It MUST fit your hub. Measure it then check what the sellers offer to match your exact hub diameter. Just a note, most hub adapters are made to fit a wheel with 36 spokes. If you have a 32 spoke rim, you're going to have problems.

Just my opinion, but shared by many, properly installed and maintained, the 'rag joint' sprocket adapter works just fine. It's a bit of a challenge to get it installed right but it can be done. Once aligned and tightened properly, the venerable 'rag joint' will go thousands of miles without a problem.

You need to start with a rim that is true and the spokes are tight. Trying to use a bad rim with loose spokes or a rim that isn't true will cause you problems eventually whatever style of sprocket/hub adapter you use.

Yup...and 36 spoke patterns can change.

 

[NeilJams]

I've got 36 spokes so there should be one out there of good qaulity that will fit. Pistonbikes has one for a MODUS hub, but they fail to mention what its made of. They sould give more info than just CNC fabricated.

 

[dtv5403]

I'm not positive, but fairly certain they are all made of 6061 aluminum.

 

[NeilJams]

Geez, most places add 30$ for the smaller multispeed hubs and like 10-15 for the sprocket that I want, all on top of the original 75 it cost. I'm kinda on a budget I'm mean if it was just 75 bucks I might could dig it, but thats abit more than the advanced pineapple kit at bikeberry. If anyone has recently purchased any type of CNC pineapples out there please share your experience with them. Im going to get the bikeberry pineapple and will update this thread after I have tested it out. Thank you everyone for your help it is always appreciated.

Instant shut down..lol bikeberry is out of stock and seems they've been out of stock for quite some time. This is starting to suck balls.

The rubber rag joints are not called pineapple anything.

The pineapple sprocket adapter was made by Spooky Tooth
out of aluminum and called a pineapple whatever because the
spokes fit into machined angled grooves that looked kinda of
pineappleish......

Bikebeery bought Spooky and sold off the last of the pineapples
and they have been out of stock for a very long time.

My hub size is 1.185". Will the 1.0" from the link below fit or will it be too small?

Pirate cycles sells the Manic mechanic adapter with sprocket for about $50. Contact them to see if they have the size you need. I've never heard any bad in my more than ten years in business about these adapters. I used one on a recumbent build and it was good quality and worked great. Hope this helps.

I don't think they provide a sprocket with the adapter, they sell it separately for $32. If they did I'd be able to choose the tooth count some where in the checlout area. It's on my list of options though because it fits my Modus hub.

 

[fatdaddy]

For $32 I'd center the sprocket on the hub and drill it myself using a less expensive sprocket. I think you can buy most sprockets for $10 or $12. That's what I did on that recumbent build anyway.
fatdaddy.

Jake's sells one that's built just like the MM adapter but it sounds like you can use a standard 9 hole sprocket. Problem is, The only one I saw was for a 1.5" hub. Did you measure yer hub yet? 1.5" is pretty much a cruiser coaster hub. Ya gotta find out yer size before you can start shopping for one.

Are you for sure the piratecycle adapter will fit a 9 hole sprocket?

I'm all for using my kit supplied 9 hole sprocket, but I'm unequipt to drill my own holes some purchasing one is my only option. I've emailed them to see if a sprocket come with the adapter. If not Ill just have to get a sprocket from eBay or somewhere more affordable. I've pretty much looked at all available options for a replacement hub adapter and piratecycle seems to be the best choice. Everywhere else seems to be charging for the hub size difference and sprocket or is a wierd measurement like 1.0". It would be nice if online shops would say whether or not it fits the standard 44t 9hole kit sprockets. I'll have to email them again to see if it fits a 9 hole sprocket. Thanks for the info.

Looking at your pics it appears that your rag joint is in good shape. My penny pinching brain says just keep it and use some threadlocker. If you are on a budget, like me, don't fix it if it aint broke. The rag joint can last thousands of miles. Just make sure it's all trued up and your drivetrain alignment is sound.

Just my opinion, and to be honest, I don't just pinch pennies... I beat the **** out of them.

And I share this opinion. Sprocket adapters are nice additions but far from essential. The rag joint can and will perform just fine if installed correctly.

I had the rag joint on wrong and it was eventually going to warp my wheel. I just bit the budget bullet and got this one:

I'm not happy I had to pay $10 more for the hub size I needed, but I wanted a hub adapter and this one was the best price with shipping and all the extras. Totally lucked out too as it was on sale for Memorial day weekend. Can't wait til I get it, I'll post some picks when I do.

 

[Chaz]

That is a good deal!

 

[fatdaddy]

If installed correctly the rag joint works great. Its just so much easier with a hub adapter. And my OPINION ( Just another opinion) Its just better to drive from the hub instead of the spokes. The rag joint works best with heavier spokes, I've seen 14guage spokes break with the rag joint. but I've ran rag joints on 12 guage spokes with no problems. (And yeah, good deal on that adapter.)

[Chaz]

Fatdaddy is right, the hub adapter is very convenient and you will never have to go through the frustration of having to remove and replace the rag joint every time you break a spoke on that side or want to try different sprockets. I'm definitely getting one for my new build.
