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.

Yes, it will fit. The only problem is that the twin antennae at the rear of the trike will prevent full closure at the back. Otherwise, a good fit.

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.

I tried to measure mine while on the boat and I ordered one that was too short. Thank goodness that the dealer that Amazon hooked me up with, Bryan Outboard Inc, exchanged it for just the price of shipping. I highly recommend taking it out of the boat, since you will have to anyway, and measure it and order the correct length the first time.

If your BMX has a one piece crank, this should work to convert it to a 3 piece crank set then you can use pretty much any bearing style you want. Just make sure the outer housing, Bottom Bracket, is around 2.25" and this will fit inside of the BB. Tighten the bolts down relatively tight and start putting in your 3 piece crank. You can always start with a donor 3 piece to save some money before going all out on bearings and what have ya.

My nephew outgrew his so I know longer have them. However, I measured the size of the pedals on his bike (that they were on). The pedals are 3x3. My guess (so don't quote me) is that the pedal blocks were about 3 inches wide, 4 inches long and at least 2 inches thick once placed on the pedals. My nephew is small for his age. He used these blocks on his trike from about the age of 2 1/2 until he was 4.

The hub is ISO threaded (1.375" x 24 tpi). It should work with most any threaded freewheel (italian, ISO, or british, which are 1.378", 1.375", and 1.370" respectively, all 24 tpi).

68mm is the case length, 103mm is the spindle (axle) length. you BB shell will determine your case length and threading (English is most common). Your crank arms in relation to your chainline will determine your spindle length. http://sheldonbrown.com/bbsize.html provides a table with most of the common crank sets listed. Find your crankset and under length you will find the applicable spindle length. Sugino messengers (RD 5 Bolt) and old dura ace are the only ones that run a 103 spindle length. Most of the single speeds I've seen run a 107-108. Sheldon Brown (RIP) is your "Go To" sorce for all of these sorts of questions.

I really don't know if it will fit it, I used mine on a home built trike and the horn button shorted out the first time I used it.

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.

All these hub have a standard size do a search for trailer hub specs on the internet and most will give dia depth and bolt patternsJim

@HankCostello: Your spindle is part of your bottom bracket. 133mm is quite long. So, continue use that BB, unless its worn out. The Shimano Alivio crank is JIS square taper. Your spindle will have to also be JIS if you want to use the Alivio crank.If you want to replace your BB with a Shimano: I used a Shimano sealed UN-55 Bottom bracket 68mm in mine with this crank. The ISO threadeing are either 68mm (standard) or 73mm (oversize) The UN-55 bottom bracket is available in 107, 110, 113, 115, 118, 122.5, 127.5 mm spindles when ordering.

i'm not sure, but what i did was measure the inside dimension of my rear frame where the hub bolts on. my frame was slightly smaller than the hub, so i bent my frame out, which is not neccisarily recommended, but i bent mine out with a 2x4 against the frame's post. it only needed about 3/8". i have a steel frame. other materials might not bend. also measure the hub on your current wheel, because i had to respoke my wheel with a different length spoke which was tricky to measure correctly. i would suggest doing a lot of research on the internet. there is a bike shop out of boston that has good resources on the subject. i don't remember the name, but it seems like the shop name was someone's first name. i hope that helps.

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.

Yes it would matter. The length of the device is spelled out, and take a quick measurement of your wheel spacing to ensure you have the proximity you need to make it work for your application

I'm not familiar with that model and can't find specifications online. I'll share how I found the one that fit my machine. 1: Look on the sidewall of the tire and there will be a series if numbers that show the tire size. 2: Measure the width of the hub. Measure the inside distance between the fork arms. (May have to remove wheel to do this.) 3: Measure the diameter and length if the axel bolt. . Sign on to Amazon and search for "Marathon tire- flat free". That should bring us a list of all sizes available and hopefully yours is there. (You will want a centered hub. If the hub axel diameter is larger than the axel bolt you can get bushing to fit. Hope this helps. I'm not familiar with that model and can't find specifications online.
