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? Thank you for...

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!

Not sure what to make of your question. This is a tapered crankset, yes, and it will fit on your tapered bottom bracket. It does not come with the bottom bracket (the tapered shaft that the crank fits on).

Hi Carlos; all the answers are good but I particularlly like Skips answer. I might add, Shimano UN55 is a square taper bottom bracket and the crankset has to be square taper also. Good luck.

I can't say specifically. you need to measure the width of your bottom bracket. many sizes are available

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

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.

I used this one: Shimano UN55 BB Square Taper Bottom Bracket (68x110mm)it is a 110mm length BB.

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

Well, let me see. If your Schwinn has a conventional crankset connected by a conventional bottom bracket then the Shimano UN55 should work. back in the early days, 1950's and before, Schwinn used to build bikes with a one piece crank. The UN55 won't work on that type (unconventional) of crank. If your Schwinn originally came with a 2 piece crankset with square taper BB interface, the UN55 is correct for you. Now keep in mind that the UN55 X 68MM is designed for a roadbike bottom bracket shell width. If you're dealing with a mountain bike it will be 73MM BB shell width. Also you will need to know the correct spindle length, they vary in length according to what is attached to the crank, drive side. Single, double or triple chainrings. Hope this helps.

I just realized which trucks you were buying. Any standard 70 mm wheel and bearing kit is great. Get a riser and bolt length depending on how you are mounting them and how thick the riser is. I would recommend a full kit that includes everythung. Bearings are standard sizes. Sorry I didn't read through before answering.

It should work fine. I put mine on a Venzo Scud 29er MTB that I built up. The Venzo has a 31.8 clamp diameter.

It has a lot of adjustment points. Three holes for the height on the bottom spars. At the top, the connecting arms are adjustable an the horizontal axis. It seem to me that it should work on most hard-tail MTB frames and wheel sizes (26, 27.5, 29)

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.

That's a mighty wide seat post. Most are thinner. Remove nut from the tightening screw. Must remove seat post from the frame and slip it up from the bottom. May need to remove the rubber washer/spacer. Apply nut back into the nut-sized depression. Tighten. You may have a very nice bike...and heavy-duty also with a frame that big. Good luck. I specialize in old Schwinns and Raleighs. Have fun!

Any 2.2 normal rim should work... I prefer beadlocks. I got axial rocksters for mine and i love them. They work well

Measure the diameter of the bottom bracket shell. If it is exactly 2", then bottom bracket bearing set should fit. I installed this bearing set on a 1990's USA Huffy bike and a 1970's USA AMF bike with no problems.

No , Bolts will come with the bottom bracket. Note: depending on your chain line of your bike frame to sprocket whether 9,10,or 11 may change the bottom bracket. Sunlite or listing suggested 122 mm but I need a 103 mm. trial and error !
