Different BB sizes and offsets can make this an expensive exercise (speaking from experience). This is one I would use the LBS - pay someone with experience to do it, or utilise their shelf full of different sized BB's - buy one with a "right to return" if its not the right size. Ideally take the bike in, they will probably give you the correct one first ...

There are a few of ways to find out what will fit: Research websites like Bikepedia and Norco.com and check the original spec. You've possibly done this already and found it's of little help. Pull the cranks off and remove the BB length and diameter will be printed on it. You're looking to take it off anyway. Remove everything and measure, this will be ...

I've had similar problems (clicking on the right side down stroke) before, and it is probably the bottom bracket. But the first thing to do is to check and make sure that you don't have a loose bolt/ nut somewhere. This could be in your pedal, the crank, or somewhere else in your drivetrain. If you make sure that everything is tight and it still doesn't ...

The front derailleur you are describing is called an E-Type front derailleur. This means that you have to be careful when selecting a bottom bracket to ensure that you get one that is compatible or you need to alter your chainline. In addition to a bottom bracket having: spindle length equivalent to current BB. 68mm shell English threaded square taper ...

TL;DR - Just about any square taper bottom bracket that has a 68mm shell and roughly 116mm spindle should work fine. You should be able to find one for very little money at either your LBS or online. As far as I can tell, the derailleur mounting to the bottom bracket doesn't make a lick of difference in selecting your bottom bracket. I've never actually ...

It appears that the BB shell is the 68mm English standard which means for very little money you can replace the bottom bracket and most likely crankset. A quick search on Jenson USA brought me this, which should come in a size that will fit your 820. If you'd like more details on the bike's specs for sizing, I'd recommend looking at it's page on bikepedia.

In principle it is doable. Normally sealed BB have 15 to 20 mm of thread at each side, so 4 millimetres of spacer wont make trouble regarding how deep the shell will thread in. Regarding symetry, it is even a possibility that you don't really need to intall the spacer, because what defines this is the chainline, that is, on a single speed bike, the front ...

Phil Wood make a sealed cartridge BB that can be shuffled 3~4mm off centre in either direction. I use one myself; the thread engagement is pretty solid. I see no reason why your spacer idea would be any different, in terms of reliability - try it! As long as you have at least 5 mm of threads fully engaged, and the BB and adjustable "cup" are torqued up ...

I think it's the single speed freewheel. I've just been through almost exactly the same thing with a brand new Cross Check SS. From day one I had a fast, regular clicking when pedalling, about 4-5 noises per pedal revolution. I could sometimes get it to calm down by pedalling backwards a bit. I was convinced it was the bottom bracket too, until I got the ...
