I have a custom built Trike using a Nexus I.G. Hub. Can you tell me how to determine BB length I should use?

You can measure the bottom bracket length wise, they're usually about 120mm (5"about). Not familiar with trike measurements though.

There are a few things to consider.... first bb width on the frame, then the thread type which is critical cause if you mess that up your frame is as good as done. You should look up your frame online is the best advice i can give you there. And then lastly, you have to determine your chainline, this is going to be unique to your setup. Sheldon Brown has some great charts. Actually Sheldon's website prob has info for all these questions of yours, may he RIP. However these are things that you may want to check with at your local bike shop... shouldnt be more than 25 or 30 bucks for some knowledge and the correct part, here in TX at least.

Check your old one. 97.2% of the time it's written right on the bracket cartridge unless your builder really cheaped out. OR If it's a new build it's based on what the crank calls for. The paperwork with the crank will tell you what you'd need for a proper chainline.

If its a standard frame it 68mm.Its a Euro frame it 71mm.And the width is determined by the crankset.If your using your old crankset( peddels and gears)Just measure the length of the old one that's your width. With crank arms removed.If your buying a new crankset use the width recomended by the manufacture.68 mm most common size for BB

Look if the manual of your bike or the crank arm specifies the size, or if the size might be stamped on the existing pedal.If DIY no documentation available: Measure the hole diameter on the crank arm (at the inner side, opposite to the pedal) or take one of the original pedals off your bike and measure the threaded part, you'll need a caliper for that. (That's how I did :-)Hint: Clerks at (small) hardware stores and of course bike shops or fellow experienced bikers also could help with that.

I can't give you exact inches without going out and measuring it, but I closed it almost all the way for my Triton TS-17 Tournament bass boat. It could be made a good bit wider if you need that, but not much smaller. Works perfectly for my boat. The only gripe I have is I waited so long to put on these guides. Boy do they make driving onto the trailer so much easier, especially in cross wind or current.

The 2th number in the total shaft length in mm. Take the old bottom bracket out and measure it or run the model number to get the specs. If it's a newer bike you might be able to track down the bottom bracket specs online. If it's a frame with no bracket to measure and you can't get the bike specs online "take it to a shop". Also you need a special tool to remove/replace the bottom bracket. Good luck buddy!

Count teeth on the crank you have if its the same it will fit. the other measurement is the length of the arm. Just measure the distance from the pedal to the center of the crank.

Yes it will.....the drivetrain dimensions and measurements (hub spacing) on 90% of adult trikes out there are pretty much the same.

Pull off existing hub. Wipe off grease. Is spindle tapered? If yes, measure diameter at back end and front end......you could also measure diameter of inner bearing race. If rear is 1 - 3/8 and front is 1-1/16 then your good. That's it.

My wife is out of town w/ the truck. I seem to remember Trimax has a user or tech support forum. I'd go measure if I could, but maybe the forums can help.

Reba - sorry to take so long. The hub is approximately the same length as the tire width, I would estimate 3 inches. I will bring calipers home from work to get a more accurate answer if you still are interested, Hugh

the first number (68mm) is the width of the this cylinder that holds the bearings and the axle that the cranks are screwed on.the second number (110 or 113mm) is the measurement of the axle itself. to find out what that measurement is you need to rip the cranks off your bike. they have special tools for that just in case you don't know. with a "caliper gauge" you can then easily measure the axl. but if you so far that you unmounted the cranks then you might as well remove the bottom bracket(also with a special tool).on that BB itself there should be a label with all the measurement on it.hope it helped a little. the first number (68mm) is the width of the this cylinder that holds the bearings and the axle that the cranks are screwed on.the second number (110 or 113mm) is the measurement of the axle itself. to find out what that measurement is you need to rip the cranks off your bike. they have special tools for that just in case you don't know. with a "caliper gauge" you can then easily measure the axl. but if you so far that you unmounted the cranks then you might as well remove the bottom bracket(also with a special tool).on that BB itself there... » Read More the first number (68mm) is the width of the this cylinder that holds the bearings and the axle that the cranks are screwed on.the second number (110 or 113mm) is the measurement of the axle itself. to find out what that measurement is you need to rip the cranks off your bike. they have special tools for that just in case you don't know. with a "caliper gauge" you can then easily measure the axl. but if you so far that you unmounted the cranks then you might as well remove the bottom bracket(also with a special tool).on that BB itself there should be a label with all the measurement on it.hope it helped a little. « Show Less

easiest way: measure between the mounting holes, it should be 135mm. h stands for number of holes in rim.

I measured the center hub with a ruler with centimeters on it, since they were coming from abroad. I also measured it in inches and compared it with the description on the hub caps.

I have a Cobra out-drive, and the hub fits mine. You can use different sized Props, for optimal performance. I choose to use Aluminum, and buy more than one prop. Hope this helps

Hello Laura, The bottom bracket is reverse threaded so it does not come loose when pedaling. As far as the size wrench you need i'm not 100% but you could use a crescent wrench to loosen the nut. We do not manufacturer this bottom bracket so I do not know the exact size mm for the ball bearings.let me know if this info helps you at all. Thank you!

I bought this item and have installed it for my father-in-laws RV, but I'm unsure of what you mean by appropriate sized hub? Please explain and I may be able to help you.
