Saved my bike from the grave after I found the bottom bracket threads were gone. Use Loctite or it will come loose even when torqued. Working great after a few hundred miles.

Bought this to replaced the damaged bottom bracket where the internal aluminum threads were damaged beyond repair and was told it was junk. I did have to remove & deburr to allow for the installation which only took minutes to restore the bike. Excellent product, it replaced the original threaded 68mm x 122.5mm tapered square perfectly.

I was given a French bike without crankset or bottom bracket. I thought, no problem, because I have a lot of French parts (vintage French have a different thread pitch). I then learned the BB threads were stripped. I always wanted to try one of these, and it worked out great. The vintage bike forum said to be wary about BB thickness (internal diameter) being slightly off but this Sunlite part was very snug. And there was no need to adjust bearings like traditional cup and cone BB's, so double bonus.This is an asymmetric spindle, meaning the drive side is longer to accommodate the crank, but as it turns out, with the crank I had, I needed to reverse the BB so the shorter side went to the driveside. This was necessary to get the front derailleur range to work. Nevertheless, the result was excellent. Very smooth bottom bracket. Will definitely buy again if needed. One thing to mention, spindle lengths must match the crank and it differs depending on the model of the crank. My Shimano 105 crank needed a 107mm spindle and the closest Sunite offered was 110mm, which is why I had to flip the spindle.It saved the frame for me. Worth the price.

It is expensive, but it is clearly good quality, and will fix up any bike it fits in. Mine has not slacked yet with a few dozens of kilometers on it. Shipping to canada took about a week.

I received this package in Canada about a week ahead of estimated arrival time.It came in a box with a set of instructions. It was not overly oiled/greased, and it even had a tiny bit of corrosion on one of the square pegs. The threads weren't anything to write home about, but once you get them threaded they seem to stay put. The bearings are smooth and there is no play whatsoever. Overall, it was deliciously machined.HAVING SEPARATELY PURCHASED THE NECESSARY 2 BB removal/installation sockets and the square crank remover, I got right into fixing my vintage bike which has been broken ever since the BB threads went for good on the frame. I spent about $30 on the tools, but they are good for life.After removing my cranks, the old BB just slipped out without tools (haha). When I slipped this new one in as described in the instructions, it fit perfectly. There was 0 play before I even put in the non-driveside part (the smaller part).After hand threading the non-driveside in, I used a torque wrench around 45Nm and then gave it an 1/8th turn after reaching torque. Note the non-driveside part comes with a nice washer/collar which likely helps ensure a good torque.Probably not necessary, but I applied synthetic grease to the main body of the BB before installation, used copper anti-seize on the part where the drive and non-driveside join and the square pegs, and applied blue thread lock on the crank blots.I've put it through some vigorous riding and it has been solid so far. I will come back and revise my review of I encounter problems, but I think you won't be seeing any updates from me.

A while ago i bought a Mongoose Torment HD from Kmar that was on sale because the store was closing. Much to my dismay on my ride home it developed a thunking noise each time i pedaled. I rode it a few more times and the sound got worse, so i decided to look into it. Turned out that my bottom bracket was cross threaded, which caused the bearings to not sit properly in their races. That allowed the entire crank set to wobble, which under the pressure of pedaling made the noise.After much research i finally found the Sunlite threadless bottom bracket. It is literally the perfect fix. It went in so easily and well that I don't understand why bikes do not come with threadless bottom brackets to begin with. I dont see the point of these things threading to the frame at all.You do need 2 Shimano style BB tools, which are about 10 bucks a piece for the BikeHand ones, but after dealing with the stock bracket on the Mongoose and the ridiculous tools you need for that, and subsequently stripping/breaking the tools because the store had somehow torqued the bracket to the frame so hard that they had obliterated the aluminum threads on both sides of the bracket, I will gladly spend the extra 20 bucks for the ease of use the tools grant.It took under 10 minutes to install the bracket. It goes through the bracket hole in the frame, and the flanges on either side automatically align it so it is true. Its got sealed bearings so you do not need to worry about grease of any kind.It does come with the bolts that you use to tighten the pedals on with. I know the picture shows them but some reviews i read said they needed to buy those.That being said, the packaging this came in was atrocious. It comes in a single ply cardboard box inside a shipping bag. My bag was tatterd, and the box inside was even worse. The bolts had actually fallen out of the box, which was completely open on both ends from being crushed, and i was very lucky that they did not fall out of the bag entirely because it did have a couple small holes in it. Somehow the bracket itself was just fine, no scratches or issues.Overall, very happy with this bottom bracket. It is sturdy, the bearings are silky smooth, and its about the easiest thing to install.If you have a cross threaded or otherwise damaged bottom bracket definitely go with this as a cheap replacement!
