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.

It will work on any length spindle ---- spindle length (axle length of bottom bracket) determines the chainline. However you must have a square taper bb for this crankset to fit. If your bb is Shimano , Truevative, Suntour, etc, you should have no problem. If you have an off brand bb there could be a pitch (slant of the taper) issue though.

For most instances the medium option will work. Shimano actually calls them long cage and super long cage. The long cage model is usually used on 29ers with triple fronts and 36 tooth rear large sprockets but a medium will work on a 42 tooth 1x conversion.

I actually just did a 1x10 conversion with 32 tooth up front and a 42 tooth in back. Still works flawlessly. Definitely start with a new chain though,narrow wide chain ring up front and One Up extended cog in back with the special mad 16 tooth cog that replaces your 15 and 17 tooth cog.

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

they sent me a 27.2 when I ordered a 26.8... they had told me it was indeed a 26.8 when I asked them BEFORE I purchased... they refunded my money... ask them before you buy it! I wanted one for my old diamondback ascent mtb.... i'll just keep riding the nice aluminum one I found elsewhere for now, besides, the weight is almost the same within a few grams....

If your bike has a bottom bracket with square taper JIS. If not, you will also have to replace the bottom bracket.

This fork in here is a 1 1/8 non tapered. it works but you need to look for the tapered version.

I think it's probably just the thing. My bike is 20" and all the stands I had before were cast aluminum and broke within a couple weeks. They cost >$25. This one is steel and cost a lot less and that was installed over six months ago. Good luck!I don't know what a 1 or a 4 means. I didn't pay attention to any size codes and don't know what I have, maybe I got lucky.(For once).

"bottom bracket must measure 123mm from one end of the spindle to the other end " AND the bottom bracket must have the correct offset, measure from the center of the bottom bracket to the end of spindle. Many bottom brackets are symetrical (same length on each side), some frames are not, resulting in one crank leg sticking out a little further on one side. Often this is not a problem.

The bearings consist of two sealed cups that thread into the bottom bracket on each side. The crank is attached to a hollow shaft that slides through these cups. This design is called Hollowtech II by Shimano. I'm not sure about the width, as it may work for a range of widths. I used this to replace a 68 mm English threaded BB on my 2008 Specialized Hard Rock XC Disk and it worked out well. It comes with plastic spacers that allow you to adjust the chainline (distance between the seat tube center and middle chainring). I believe all of the spacers must be used, but you shift the cranks side to side by changing the number of spacers under each bearing cup.

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 googled it and it says its a 68mm english bottom bracket. Depending on what crank your going to use will decide on what shaft length to use on your bottom bracket. Once again.... DO YOUR HOMEWORK!!!

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.

My husband says that if you have a three point mounting plate your shaft diameter won't make any difference. You have to order a jack with a three point mounting plate. He says you have three bolt mounting plate that holds that jack into the tongue. I hope you understand this better than me. I ordered it at my husbands direction.

This crank set is for a square taper bottom bracket. I bought an Avenir Octalink Crank Puller from Amazon.

I'm using my 12-30 with an Ultegra short cage, and it works just fine, this despite the fact that when I originally set it up the opinions expressed at the time said it would not work. I believe even Shimano had a company opinion that it was not appropriate to run that combo. That said, you are still at the mercy of "try it and see if it works." If it were me, I'd take the chance, but you have to make the final call. As in my previous answers about this set-up, I'd remind you to not give up if it seems it won't work initially. Chain length is critical in being able to keep the idler pulley from contacting the 30 tooth cog, and I think I may have messed with the stop screw as well. I wish you the best of luck!
