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.

your handlebars go through the headtube which is connected to the deck. above and below the head tube are the headsets that hold the bearings in place. The clamp hold the handlebars to the forks, under the clamp you will find two nuts. First try tightening the bottom nut to see if it just came loose, it probably didn't. Second loosen the clamp and remove the handlebars, then loosen the locking nut, (the top one), then loosen the bottom nut. Be careful you will see a bearing in the top headset and the bottom headset if it all falls out, don't be surprised, if your handlebars cannot be fixed with just tightening the bottom adjusting nut then you will need to replace the bearings. You can get replacement bearing for about $20 a set at a place called urban gravity (www.ugscooter.com). I learned this the hard way if you don't keep the lower adjusting nut locked down with the top locking nut you can wipe a bearing out pretty fast, plus it comes with cheap bearings. hope this helps

I would suggest upgrading your bearings. You can get something faster. Skate shops or the Internet will have a wide selection to choose from. Research online about the various bearings that are available. You can pick them up pretty cheap or go all out and get high end bearings. You can also replace the wheels depending on what surface you skate on. My daughter has not done so but you can get a recommendation from a skate shop. I would definitely replace the bearings if you want to go faster. I hope this helps.

I Had a similar problem. The chain guard wouldn't let me mount the motor low enough to attach It to the bottom rail. I bought a new bracket from kingsmotorbike.com . They have just about any part you would ever need. You could possibly get a longer bolt from home depot . You may have to get creative . Goodluck

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.

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.

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.

This is from the seller's [Low Baller] storefront - Contact this seller Phone: 909-979-7392 Not sure if this was the one I used, but recently I received one that sounded like a bearing was bad, they were very helpful and shipped a new one very quickly. Good luck.

there should be a label on the bottombraccet itself with all the specs on it. if you cant find the info on the specialized web site the simplest is to remove the bottom bracket and take the info from there.

How new? My bearings went out after 1.5 years and still waiting on replacement- it went out in September! It sounded almost like a metal on metal grinding.

the bottom bracket refers to the axle that the crank arms attach to... the crankset comes with everything to attach it to your frame except the wrench to tighten it

I just got mine and I'm wondering if I should return, my drive shaft appears slightly bent and when I grind with nothing inside it scrapes ceramic on ceramic at one section of the rotation. :(

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.

The Mongoose 21 speed should be OK with this freewheel. The Mongoose normally came with freewheels as opposed to cassette and freehub. The freehub is notched and the cassette slides onto it. Freewheels are threaded and you will also need the freewheel removal tool. They are difficult to remove but if you google for "Sheldon Brown freewheel" you will come up with ideas on how to get them off. Hope this helps.

its supposed to be 1 year - I've purchased 4 so far & the first 2 went bad in a short period - I contacted the place i purchased them (Hub & Bearing Warehouse) & they NEVER, EVER responded or acknowledged my emails or calls - DO NOT BUY FROM THEM! - these last 2 thru Amazon - personally, if you are planning to keep your vehicle longer than a yr, I'd spend a little more & buy an assembly that has Timken bearings - JMO

I had bad luck with bones reds, had to return them twice because of some grinding issue, then got some super reds worked perfectly and runs extremely smooth especially if you clean and lube them on occasion. If you would want to go the cheaper route you have the possibility of getting a few bad bearings vs paying a little more getting better quality. as for which ones last longer I do not know.

Hey Roy, I'm not sure if there would be any brackets out there for that series now. It might have to be a custom job or something you'd have to retrofit with a newer bracket.
