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.

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.

With crank arms removed.If your buying a new crankset use the width recomended by the manufacture.68 mm most common size for BB

The only problem you >might< run into is clearance between the forks and the tire or between the fender supports and the tire, but honestly, it should fit. I've run 26 X 2.50 tires on my trike that came with 26 X 2.125 tires originally, and while the clearance between the forks and the tires was snug, they worked...and were a lot more comfortable at operating pressure. Hint: Keep your tires near or at maximum pressure for the smoothest ride. It's counter-intuitive, but that's how it is.

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

its going to make an old school crank, like a 1 piece design) adapt to a cartridge style bottom bracket, you decide the size of the bb, depending on the crank choice. hope that helps

I am not sure of this but I think that Kreg tools and Triton are in partnership. So you can check with Kreg and see if they can point you in the right direction.. Also I'm sure you know this but make sure plunge lock is off. Also if it gets to low your crank handle will not reach the fitting that it goes into and just spin around. Hope I didn't insult your intelligence by some of the simple suggestions.

I purchased this to use on a Tricycle conversion kit from Bicycle Designers. It was too wide to use on that. This conversion kit is actually a Sturmey-Archer 5sp hub. You can get the specs on the Sturmey Web site.

A Retrospec Crankset has a crank arm length of 165mm. No need to worry about pedal strikes!

In general it should work, its about the width of the rear fork and the dropouts. Since you've had a Nexus it should be good to go.

Sorry, I can't find a record of my Bottom Bracket order but would recommend checking out this page for advice.http://sheldonbrown.com/bbsize.html

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.

if you have the tools the simplest way is to rip out the BB and check the label that is on it. the few times i changed the BB it did not even occur to that there could be a difference. if all your screws on your ride are metric then the BB may be as well.but if you can check the label on the BB that be your best bet.

The size you need is determined by the size of your hubs not your axle. the bearing buddy is available in 12 different sizes from 1.781 inches to 2.717 inches. the most common are 1.98 inches on must wheel hubs. So, you must identify what the inside diameter your wheel hubs are where the grease cap is inserted to chose the correct Bearing Buddy. You can easily do this by prying off the existing grease cap and measuring the width of the portion of the cap that fits into the hub. If that is only one inch than the bearing buddy is to large for your use. I hope this info helps you, Alan

It will depend on your spoke lengths and if the flange diameter of this hub is the same as your current one. I found this calculator (http://www.prowheelbuilder.com/spokelengthcalculator/) to be the easiest to use, because it graphically shows you the measurements needed. I needed to buy new spokes and nipples for this hub(because the flange was wider than my old one) but it was well worth it.

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!
