My square tapered bottom bracket (stbb) is 68/122.5. I have an old 1999 Specialized Hardrock that uses a VERY primitive looking stbb (like ball bearings, and couple of rings) that looks nothing like on the picture. Would it still work?

I had a similar setup before switching over with no problems... BEST move I made was switching from the old to the UN55 Shimano BB...

I put this one on a cheaper Huffy mountain bike with a solid straight shaft and a bearing set on either side! It was a great upgrade and worked perfect. Very simple to install and I think it should work on your bike with problem.

Sounds like you currently have an 'adjustable BB' and upgrading to a cartridge BB is certainly a move in the right direction,chances are it will work, and if not, send it back.....no biggie....good luck.

If you're talking about a square taper bottom bracket, no I believe you'll have to buy a bottom bracket separately.

I put the calipers on my bike post and it shows it to be one and one-sixteenth inches (1-1/16"); I had to use two of the three plastic shims that come with it to make the rack fit properly on the post. Without taking the rack off to measure the opening without any shims in place, it appears it should accommodate a post upwards of 1-1/4" thick. With all three shims in place it should probably fit a post as small as 1", or possibly just a little less. The three shims included should allow it to fit about any standard post, I would think, but not sure what acceptable standard post sizes really are.

A 113mm bottom bracket will potentially give you chain alignment issues. The suggested 110mm BB's are readily available and its suggested by the manufacturer to use that length.Thanks

the specs on that area a 44 to 48 tooth outer ring, the main thing is also its a 9 speed, I had a seven speed rear sprocket, didn't work for me, so be sure and check your rear sprocket. Then look for a 3 x ?, whatever you have, then you should be ok.

what does 1108495 2b21 fit most small block that have the staggerred pattern also have the other pattern

Pedal spindles come in two measurements: 1/2" and 9/16". It may seem similar but when you hold them side by side it makes a big difference. The good thing is that most Shimano cranks have 9/16" ports for pedals. This one should be 9/16"
1405580
9/16 is most likely referring to the size of the wrench needed to use this crank puller. I would recommend using an adjustable wrench with this crank puller. This crank puller should work if your bottom bracket is square taper.

I threw this very same Sunlite 103mm BB on an old Trek for the purpose of converting to single speed.Now depending on your frame..You may need a somewhat longer Spindle or BB.Or it could possibly be a Front derailleur adjustment issue.Good luck! Eddie

You need to make sure first that your bottom bracket supports square-tapered cranksets. Then also you need to make sure of how many speeds your bike has. This setup is pretty standard so if you can fit square Taper and have 3x8 speed then it will work

if you have the old style or AMERICAN style, that is NOT threaded inside the frame, punch out the races and use the TRUVATIV BB conversion! YOU WILL BE VERY HAPPY YOU DID! There are a TON of videos on how to do this, check out bikeman (I think that is his youtube handle) and you wont be let down! JUST MAKE SURE YOU INSTALL THE DRIVE SIDE PROPERLY AND LINE UP THE CONVERSION BEFORE YOU SEAT IT INTO THE FRAME! The screws to the conversion will pull it TIGHT but make sure it is in far enough to not strip the screws or adapter! THIS BB is one of the best values in the industry! I dont recommend any UNDER this model, even though they are VERY RELIABLE. THIS is a small price to pay and while you are there, I recommend an upgrade to your crank set to bring you an upgrade that will breath life into that nice HARDROCK! IF YOUR FRAME IS ALREADY THREADED, no worries, this should work!

Sorry - I don't have this tire to check, but Continential only lists 27 x 1 1/4 with ISO 630x32.The general rule for bicycle tires IS fractional sizes and decimal sizes DON'T MIX. It's a valid question - although I'm not aware of that problem with 27" size, I have definitely experienced problems with old 26" sizes even within the same inch size designations.I suspect someone that was unaware of the mismatch issues just used the decimal designation by mistake. Best to check the ISO numbers of the old tire ( that did fit ) if possible - look at the larger number, that's rim diameter. In this case you want 630-xx (for a 27" tire).

i put the Burly Slammer kit (B28-1000) on my 1992 HD 1200 Sportster and I love it!!! Here's the deal though, i had clearance issues with my back tire scrapping the bolts on the inside of my rear fender after i lowered it, and i was really frustrated with it. So, instead of trying to return it (since i tried them on and technically used it even though it didn't really fit) i decided to reverse the bolt heads on my rear fender strut brackets to where the heads are inside the fender rather than the bolt ends and i had to modify my rear turn signal mounting bracket as well. If i would have know this would happen, i probably would've paid a little extra and got the progressive ones instead...BUT, your bike is a 2001 which is 9 years younger than mine so i would think it's safe to assume the kit would fit your bike much easier than mine. My friend has a 2009 and he has the Slammer Kit as well and his fits perfectly with no mods necessary. The ride is much stiffer than stock, but it's not bad at all and really, if you lower your bike expect to have a stiff ride. it's easy to install if you have a couple of people to help and you're somewhat mechanically inclined as we installed it ourselves with no issues. If you're looking for a good price, DIY quick and easy, one size fits most, with a pretty good ride then i would recommend this product.

I am new to building bikes as well and am having a hard time figuring out what size bottom brkt to order.
1948489
I think so. That bike looks like it has 25.4mm handlebars (http://www.specialized.com/us/en/bikes/mountain/hardrock/hardrock-disc-se-26#specs), which is fairly standard for newer bikes.

You need to buy a longer BB to account for it. I'm going through the same issue. What I haven't seen a comment on is how this affects the non-drive side. Would you notice it when pedaling, especally if you "clip-in". This chart gives you the symetrical equivalent - http://sheldonbrown.com/bbsize.html . My 3T spindle would need a 130 symetrical BB.

Hey Gordon, I bought this as a replacement crankset for my Trek FX and haven't gotten around to taking the bike apart yet. All I can tell you is that it is for a square taper BB. Check this website. http://www.rivbike.com/product-p/cr1.htm
