Sunlite Bottom Bracket Set

April 2015 EDIT: WARNING, when you select the 65mm size and then click "Add to Cart" the WRONG ITEM is added now. It adds the "mini" bearing instead, which does you no good at all because it is the wrong size. Unfortunately this is still the ONLY bottom bracket for 1-piece American cranks sold on Amazon that isn't painted... so if you do decide to try to buy it please double check the item description in your cart before you pay for it!!! The actual item this ad is for is pretty good. The mini version I assume is also pretty good but it's just a different size that won't work if you want a full size kit. I luckily found that when I was ordering another kit for my brother's bike. ALWAYS CHECK YOUR CART BEFORE YOU PAY. So make sure you first select the 65mm size; that should add the correct product to your cart.I bought a Schwinn cruiser bike (and I will never buy Schwinn again) and every part was designed to the wrong tolerances or broken right out of the box. But I like the frame. So I've been rebuilding the bike with NEW non-Schwinn parts one piece at a time.The bottom bracket bearings were PAINTED originally, and the crank shaft was TWISTED. The bearings were rubbing unevenly because of the twisting, and they were not rolling smoothly because of the paint (which started to flake off and get stuck in the bearings, making them even less smooth than before) so I took them apart and junked them. Bought this kit as a replacement. It arrived in good condition and quickly. I have not installed it yet but the bearings seem to slide pretty well inside the cups, so it looks good.NOTE: Make sure your bike uses the right kind of bearing. There are five or six different types. This set is for the old-school American bikes with the one-piece crank that slides all the way through the bracket and then you screw the pedals DIRECTLY onto the crank. If your pedals are attached to two separate arms, then this is the wrong type of bearing for you.Another NOTE: To see if your bearings need to be replaced, remove the crank arm (w/pedals) and remove the guts of the bearings. DO NOT beat the cups out of the hole yet though; leave them in. Wipe as much grease out as you can. With the bike on its side, put one of the bearing rings into the cup, and place the cone (inner screw/cover) on top. Spin the cone with your fingers. If it does not spin freely, or if it wobbles a lot, then you probably need to replace the bearing. Remember to flip the bike over and check the other side, too. If you've never done it before, check YouTube for some how-to videos to remove and replace it, or take it to a bike shop.Ok, so this kit is designed for a 24 thread-per-inch one-piece crank. All the nuts here are threaded for that specific crank. There are other "TPI" (thread per inch) numbers but this will not fit those; the nuts won't screw on right. It's meant for cruisers and BMX bikes with the BIG bearing bracket hole. If you have another type of bearing in there already, then you can still use this as long as the hole is the right size (2 inches) and you have to remove ALL the parts from the old bearings... this probably will include taking a hammer and a punch or screwdriver to beat out the old bearing cups. The bearings are just exposed steel balls, but they are contained in a ring spacer so they're not so easy to drop and lose. When you're installing a bearing, make sure you use LOTS of grease. Really. In this case, too much grease = not a problem, but too little grease = bike won't work right.Pro tip: Can't find a 2x4 and don't have a bearing press? Build one for cheap! You will need a 6 or 8 inch long threaded rod. Each end of the rod will need a nut (you only need to screw one end, so the other end is allowed to have a fixed head) and two washers. The one that goes right against the nut is a 3 inch steel washer. The one that goes against the bearing should be a 2.25 to 3 inch rubber washer. You put one nut, one metal washer, and one rubber washer onto one end of the rod; feed the rod through the bearing bracket AFTER getting your bearing cups loosely fitted by hand; and then you put the rubber washer, steel washer, and nut onto the opposite end of the rod. Screw in the nuts to apply even pressure to both bearings and squeeze them completely into the bracket. You might need extra washers between the nut and the big steel washer to adapt from the diameter of the rod to the inner diameter (hole size) of the big washer, so the nut doesn't fit inside the washer.

I have a cruiser bike manufactured in the late 50s. The entire crank system (bearings, cups, crank, and pedals) needed replacing. I was skeptical, thinking the new parts would not fit well. Seventy years is a long time for a parts standard to remain unchanged. But apparently the standard for bottom bracket cuts and bearings has remained the same. This set fit perfectly. It took a hammer to get the old cups out. And it took a hammer to get the new ones in. But no deformation, and the new cups went into position without difficulty. The bearings spun as they should. FWIW, a new crank and new chain wheel also fit perfectly with this set: more unchanged standards. The crank fit though the cups easily for installation. After packing the bearings with grease, the process of tightening the bearing/cup set in place--not too tight, not too lose--took a few minutes. Everything is as it was before, without the wobble and grinding of the old parts. I've ridden since installing these and everything works fine.

I love sunlites products they are extremely high quality. I used this bottom bracket set to repair a huffy cranbrooks crank. The bearing and race that came with my bike were absolutely dry with no grease inside whatsoever. Literally bearings were falling out when I took it apart. Once I cleaned everything and knocked out the old bearing cups and lightly tapped in the new ones that came in this kit, I put a generous amount of red high temp grease and this thing is as smooth and tight as it can get. I’m super happy with this kit and I know and trust sunlites quality every time. I highly recommend this product especially if you don’t want to ever take you’re peddle crank assembly apart ever again.

I needed to replace the bearings, cones, and cups in a 1967 Schwinn racer bike. While the cups did fit the bottom bracket, and the bearings fit in the cups, but the cones, nut, and washer are threaded correctly, they are too small to fit on the old crank. Guess its the curse of old bikes.

Suspected this Sunlite Bottom Bracket Cup Set was exactly what I needed for the Pooboo W258 Incumbent Exercycle. And it is!!Had to be creative to strip out the worn Cups, and install the new ones from this Sunlite set.There are many install/removal tools out there, but I used another method. Worked beautifully. And the Sunlite repair kit is perfect!The bike now runs smoother and quieter than when I got it new two years ago. I ride it every day for 30 min. each morning. Several other family members have used it some too. So it gets a lot of use.Thanks SUNLITE, it was just what the doctor ordered!

The sunlight bottom bracket set that I ordered for my client worked perfectly for his bike. I noticed on his old BB set something just wasn’t quite right. Which at first I was never able to figure out what was wrong, but I then concluded that the parts were just worn out and not working like when My client first purchased it or when I first received his bike. So I ended up first letting my client know that his Bottom Bracket, Crank arm and chainrings all needed replacing. So I replaced everything and decided to just start fresh. Anyways this new BB set worked great. I didn’t use the bearings that came with mostly because they weren’t Hartford USA Bearings. So I used some used Hartford bearings I had and they worked out perfectly as well as using Park Tool PPL-1 Grease which really worked out. The BB went together without too much trouble just needed to tighten the cotter bolt a little bit more and it worked out great. Plus it looks great with the sunlite crank arm and Sunlite double chainrings. It all looks Very nice! I highly recommend this Bottom Bracket set of you have a Ashtabula crankset or an American 1-piece crankset.

The outer nuts were great keeper nut was fine,,some of the bearings fell out of bearing case had to put back in and bend spacer in place ,,not so percision,but still workable product
