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!

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.

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 wish i could say yes or no. Your model looks bigger then mine. To be honest since it was just one weight i never went to trouble of trying it on mine. I just bought some aggressive rear tire . sorry i am no help.

I am not familiar with that bottom bracket. My fist question is : is that a square taper style bottom bracket? That's what you need at the most basic level . there are other factors that come into play : straight road bike style chInstays or MTB style chainstays .can you replace the spindle on that bottom bracket if nessary? That might be the only way to decide the correct spindle for your bike and the sugino crankset. Or... Quick answer : take the whole thing to your local bike shop to see what they might say. I hope this helps. Perhaps there are some other amazon customers out there with experience with this bottom bracket? I am not familiar with that bottom bracket.

The hardware I received only works on straight forks. As in the Custom models not Classic. And you can't match it up with brackets that work, or I couldn't.

I running a 180 mm front and rear on my trail bike and my riding buddy's are running 203mm. Just need to get the right "shimano" adaptor for the rotor you are planing to run.

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

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!

Johnny, Don't have those dimenions as I have added saddle bags and not convenient to measure. However I can tell you that I matched up the front mounting holes and the rear holes were about 2" off. I marked and drilled those holes (on the sissy bar mount not the bike frame) out myself and it fit just fine. This was the best priced one I could find. Reasonable price for the quality you are getting. A heavier made bar would be a lot more expensive.

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.

You need two pieces of information to determine whether this Shimano gear cluster will work on your bike. First question: is the rear gear cluster on your bike a freewheel or a cassette? Look here (http://www.sheldonbrown.com/free-k7.html) to help you determine. I've looked at the Huffy mtn bike owners manual (http://www.huffybikes.com/pdf/ownersmanuals/7f448214-b108-4c48-93eb-972b6c9e4a17.pdf) and page 36 would suggest your bike has a freewheel. The Shimano you are asking about is a freewheel type gear cluster, so if you answer yes to the first question, then on to the second question. Second question: will the Shimano gear cluster fit on your bike? I am talking about the width of the gear cluster; measured from smallest gear to largest if you are looking at it from edge on. According to Amazon's listing, the Shimano is 1.7". Measure your existing cluster and then decide. Look at this (http://sheldonbrown.com/harris/freewheels.html#6) information to help you. Finally, if you decide to go for it, you will probably want to purchase a freewheel tool to help remove the old and install the new. You may also need to know how to readjust your rear derailleur (described in the owner's manual) if the gear clusters are somewhat different in spacing and width. Good luck

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.

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.

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

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.

Hey Will, just wondering if you bought this bike and successfully put 32's on the bike? I just saw my friends tires and 23's are way too skinny! Not to mention I'd bet you'd feel EVERY piece of dirt. I'd like to know before I commit.
