Bottom bracket installation requires specialized tools. So even if you are able to find the propper size BB you would still need to buy the tooling. That's not very cost effective for something you're only going to do one time. I would weigh out the cost of taking it to a bike shop against the price of a new bike. Good luck

No. BMX bikes typically use a different style similar to this: http://www.amazon.com/gp/aw/d/B000IQBBKO/ref=mp_s_a_1_1?qid=1417644028&sr;=8-1π=AC_SY200_QL40

No way for me to know...It is best to take it to a bike shop. They can measure it and suggest a replacement. It should run no more than 25-30 dollars and about 15 or so to install it. It will be worth your money to do this because if you do it yourself you will also need a bottom bracket tool so you probably have to spend about the same or a little more than if a bike shop does it for you. Call around and get 2 or 3 quotes.

My first suggestion is to read all the previous answers on the UN55 before you attempt to replace your bottombracket assembly. If you can remove the spindle, look to see if the specifications of the spindle are embossed on the spindle itself. For example, my Shimano spindle has specifications of 68 - 122.5 embossed on it, the smaller number is the bottom bracket bearing tube width and the larger number is the actual spindle length. Then select the UN55 sealed bearing BB that is the closest to your measurements.

This crankset comes with a hollow style BB. There is a special tool that has the correct tooth profile, but I just used a strap wrench to tighten the cup in place. Its always a good idea to chase the BB threads with the correct tap, or have a local bike shop do it. After maybe 50 off road miles, I had a breakdown, but from my rear derailleur. While I had the bike apart I noticed the cranks were turning smoothly, but not freespinning, like there was some seal friction, so it may be wiser to either use a torque wrench to adjust/tighten the BB cups. Shimano always gives very specific instructions, so thats a plus. This crankset comes with a hollow style BB.

Bearings weren't the problem. The trucks don't turn as sharp as you'd like. I told myself it was the length of the board which made the turns wider since it's pretty long, but I enjoy turning on my friends 43 incher. Don't get me wrong, it's not a bad board, I loved it. Just needs breaking into

I first started with a bearings upgrade, which totally changed the feel of the board, then I threw on a set of Gullwing Sidewinder II Trucks, I don't recommend those trucks in particular due to having two kingpins, and the board has a big disadvantage with wheelbite with these trucks, and a bit of speed wobbles. I suggest a set of Paris' or something of the like.First, I'd start with bearings, and just work from there:)

This crankset does not come with a bottom bracket cartridge. The cartridge is a separate item that can be purchased on Amazon. I use this crankset with a 110mm BB Cartridge. But, you could use it with most any cartridge spindle length probably. I use a 110mm to get proper alignment with the rear cog set on my bikes. I remove the chainrings from this crankset and make a singlespeed crank out of it for my own purposes.

No you did it right, this is one of the flaws with this system it really is not that good. I returned mine and got a heavy duty one that has a top and bottom bracket to go around the linkage as to not fall and rest on the linkage, I would return if I were you it is not a good product and made my steering much worse

Bushings. It used to use bearings but the service tech told me that they switched about a year before I bought it. It's the weak link in an otherwise really good machine. The bushings are cheap plastic material that I had to get changed twice.

I fully agree with this statement. I purchased this bike for the frame, fork, seat post, stem. I have had to upgrade the crankset, handlebars, seats, tires, tubes, peddles. They are not of quality. I now have to upgrade the bottom bracket as the bearings just shattered.

Where to buy parts for the mongoose 3.0 . You can buy parts just about anywhere amazon , ebay i've gotton parts at both places

@Austin the bearing were about the same quality as the reds bearings. Really the only difference was that they were yellow instead of red. Also the board came with yellow moranga wheels instead of yellow stims. Lastly, the bushings were garbage, but overall I like the board. It takes a little while to adjust to, but still good for tricks and pretty fun

Hi, i would assume this is on the front wheel bearing, and i hope that the other bearing on the otherside is still good? If so i would measure the inside bearing diameter because thats crucial when the bearing sits on the bearing race, from what i can see, yes that bearing would work, but imNot 100% on that answer cause i cant see the wheel myself.p.s. most bearing diameters go by the metric system, mm it could be for instance 21mm diameter accross. I hope this helps.

my son says the problem with these bearings is they make his skateboard go too fast. They are great. I used to own a Skate shop. Bones bearings are by far the best bearings you can buy.

I think it depends on how old the bracket is. We had to buy a new one at Dick's for $40. My guess is, you're better off just buying a new one.

I've had mine for about 2 months now and it hasn't cracked. It's great for beginners but I highly recommend getting better bearings, I put Bones Reds on mine and it's great. You also are going to want to fix the trucks because they are off center making it so all but one wheel touches the ground. Once you tune it, it's pretty good.

Actually, the bearings are very good. The quality of the entire thing is good. My son rides it constantly & he's never had any problems with it.

You have to use the hubs that come with the kit. The bearings are bigger and the stub shaft itself is also larger so they're a lot stronger than stock, and the hubs are really strong too. The front and rear half shaft assemblys are also the exact same with the Tekno kits so you parts interchangeability which is nice. I've been running mine for about 4 months in Afghanistan with the castle SCT setup on 3S with 6in. tall tires and the Tekno 17mm hub conversion and have only broke one front half shaft because I was running a rear locker on the street. If you are still running the stock size tires even on 3S, I don't see you ever breaking any half shaft parts. These are tough. You have to use the hubs that come with the kit.
