Sunlite Threadless Repair Bottom Brackets

Product worked as expected, arrived earlier than anticipated.

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.

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.

We got a well worn low cost mountain bike with a thrashed bottom bracket. $35 at auction. Low cost/quality, but kind of cool features like a full suspension, so kind of fun to save and throw parts at it that were worth way more than the restored bike. Ok wit that because it was an educational experience.THE REMOVAL OF THE OLDThe whole crank assembly was loose on the square taper and the bottom bracket bearings were very loose. As I started to take it apart, the pedals were very easy to remove. Then it got difficult. The normal tools and techniques would not work. I wound up tapping out the adjustable cup by smacking the edge of it with a chisel to unscrew it. The fixed cup was even worse. Normal tools wouldn't break it loose. Even the 5/8" bolt/nut/washer stack trick didn't work. Even applying an Ingersoll-Rand *impact* wrench to that 5/8" washer stack didn't budge it. I then took a Dremel cutoff wheel to the fixed cup. I cut a vee to relieve stress. But not much help. I finally made a half dozen toe-holds for my cold chisel and was able to able to tap it out. Slow progress with each hammer whack for the first couple of revolutions. Next couple of revolutions it made reasonable progress with each hammer whack. After those difficult first four revolutions it was finally finger loose.After all of that trauma in getting it out we suspected the worst and inspected the threads and the first couple of threads were pretty galled. Even though I could have tried deburring and removing the first few threads I didn't want to risk a new bottom bracket cartridge on those janky threads.I saw a handful of YouTube videos that highly recommended this product. I lightly flattened the burrs and rough edges on the faces of the bottom bracket shell of the frame with a file and then cleaned everything with brake cleaner. We used red Loctite on the threads of the new cartridge and torqued it in. To be fully transparent, I think I gave it a little extra torque after the wrench clicked because it seemed kind of light. *It went in so quickly and easily!* We'll let the Loctite cure and then install a new low cost 1x crankset from "Action."Very happy with this purchase. It allowed us to save the cool fully suspended aluminum frame. Will report back once we have a month or three on riding it.

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.

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!
