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!

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 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!!!

The 2th number in the total shaft length in mm. Take the old bottom bracket out and measure it or run the model number to get the specs. If it's a newer bike you might be able to track down the bottom bracket specs online. If it's a frame with no bracket to measure and you can't get the bike specs online "take it to a shop". Also you need a special tool to remove/replace the bottom bracket. Good luck buddy!

130mm BCD is the spacing. It did not work for me. I wound up getting a new crankset, which also required a new lower bracket with longer spindle. It all worked out in the end.

not sure. but if the hardrock special has the "brazed on" bolt holders on the frame, I would guess that it would work out. if there are no brazed on bolt holders, like my bike, then you have to use the extra smaller piece shown in the picture of the rack. that made it more difficult to install (had to buy extra bolts, as not enough were included) but it did work

This will fit a 68mm bottom bracket. It is a pretty standard size. It comes with spacers to adjust for the width of various bottom brackets. I can't find specs for your bike, but your local bike shop would easily be able to tell you. This is the cheapest place you will find this set.

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.

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

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!

The Bottom bracket is somewhat adjustable, but I'm not certain it will fit. It is one sweet crank set and worth research. Some of the vendors have different crank arm lengths; also worth looking into. I wound up with 175's which are fine but I'd have been better off with 170's. Have Fun!

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 really think it depends on your chainstay clearance, chainring and crank arms. What I did to figure that out was to use websites like this one: http://sheldonbrown.com/chainline.html to figure out what length bottom bracket best worked for my bike. If you are running a triple, you should be at 45 (I'm assuming you are because you specifically asked about a chainline of 45), but a double should be 43.5mm...and on and on depending on your bike and gearing. You can also adjust the spacers on the back axle as well, but this shouldn't be necessary if you know that your rear (sprocket end) is at 45mm, which is what you are trying to achieve (explained here: http://www.velodromeshop.net/index.php?p=page&page_id=chainline). Sorry, not an easy yes or no answer. Just check those sites out and do the measurements and you should be ok. Hope I helped...good luck!

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 !

The diameter won't likely be your problem. The length was the issue for me. It was a little too long, and wouldn't lock. However, I was able to grind part of the bolt off and get it to work. You might want to measure the space between your forks to get a better idea it it will work for your bike.

If your bottom bracket cartridge has a standard square taper JIS spindle - then it most likely will work. However, there is the possibility that you might have to change the cartridge to a different length (possibly shorter, like a 68x110) in order to get the correct alignment between crankset and rear cassette.

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)
