Since a) original cottered cranks for this bicycle are rather difficult to find (especially in good shape), and b) it made perfect sense to "upgrade" the bottom bracket to a more modern bottom bracket and tapered square crankset, this seemed like a good choice. This is the second tapered square bottom bracket that I purchased. The first one, purchased at a local bike shop, had a 113 mm length and the chainline wouldn't line up once I put the new crankset on. So, I ordered this one (with a 103 mm length) from desertcart. Even with the 2nd day shipping, the price was less than I would have gotten at the local bike shop. This was the LAST piece I needed to complete the mechanical portion of the Nishiki rebuild, so I didn't want to wait for an extended period of time to complete the project -- which is why I went with the 2nd day shipping. The item arrived on time, as scheduled. When I first went to inspect the item, I noticed that the left support fastener was cockeyed on the bottom bracket (probably as a result of UPS's typically "gentle" handling ... ugh!). It wouldn't budge by using just my hands. So, I carefully screwed the left support fastener into the right side of the bottom bracket housing (pay careful attention to the thread direction!), and was able to apply enough gentle pressure to be able to remove the left support fastener. Be sure to apply a very thin coat of grease to the threads on BOTH sides of the sealed cartridge bottom bracket. Insert the right side first, and then screw in the left support fastener (again, pay close attention to the thread direction!), and torque both sides down according to specs (printed on the box). Then, apply your crankset and left crankarm, pedals, mount the chain, adjust the derailleur (if necessary), and your repair is complete. This sealed cartridge bottom bracket is very smooth -- being that it rotates very smoothly. The entire item is made of metal, so there are no plastic parts. Overall, this is an excellent product, and exactly what I was looking for to complete the rebuild of my Nishiki. I am very happy with this item. Oh ... and I now have a very roadworthy vintage bike to ride around town! Review: solid bottom bracket - UPDATE 9/10/2013 This bottom bracket is still holding up, I have had no issues to speak of with this part. I like to think I have put it through its paces. I have purchased other Sunlite products and have been quite satisfied. UPDATE I have put roughly 300 miles on this bottom bracket and everything is smooth since it arrived in the mail. It works just fine for my single speed commuter bike. After 300 miles there is no wiggle in the bearings and everything seems good! I am happy with my purchase! ## Features - Sealed cartridge ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003COD29C | | Best Sellers Rank | #1,129,904 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #734 in Bike Bottom Brackets | | Brand Name | Sunlite | | Customer Reviews | 4.3 4.3 out of 5 stars (140) | | Date First Available | March 17, 2010 | | Item Dimensions LxWxH | 5.5 x 1.6 x 1.5 inches | | Item Package Dimensions L x W x H | 5.6 x 1.7 x 1.3 inches | | Item Weight | 0.01 Ounces | | Manufacturer | Sunlite | | Model Year | 2012 | | Number of Items | 1 | | Package Weight | 0.34 Kilograms | | Part Number | 22386 | ## Images ![Sunlite Square - Comp Cartridge Bottom Bracket - 68mm, ENG, Square Taper, 103mm, Steel - Image 1](https://m.media-amazon.com/images/I/41yQqxpvz+L.jpg) ## Questions & Answers **Q: what do the dimensions refer to, the 68mm - diameter? what is the 103 the frame or the axil end to end? Thanks** A: I don't have th BB on me, so I can't put my calipers to it. But I believe the 68mm dimension is the axial length from the out-facing end of the threaded housing (the splined face) to its corresponding counterpart. The 103mm is the overall length of the unit, tip-to-tip. Hope this helps. **Q: Mine arrived without the cup (Threaded piece on other end). Do I need to order separately or is that piece missing?** A: you can if you wanted to hurt yourself. You should have received 2 pieces in total: the bottom bracket and the cup for the other end. **Q: I have a Raleigh Grand Prix circa 1970s model and was wondering whether I need a 103mm or a 113 spindle axle length?** A: did the 103mm or 113mm work for you? **Q: Will this fit http://www.amazon.com/Vuelta-815002110-Pista-Track-Crankset/dp/B004Z8BYCG/ref=sr_1_3?ie=UTF8&qid=1418576132&sr=8-3&keywords=vuelta+crank** A: According to the link you provided the "Vuelta Track/Fixie Cranks are designed to work with 108mm BB Spindle", this item is a 103mm BB. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what I needed! *by P***E on August 26, 2012* Rebuilding a 1973-ish Nishiki Olympic 10-Speed bicycle, the original crankset was toasted, thanks to a botched backyard repair job.

It was for my fixed gear bike that I use for courier work. The stock bottom bracket before this one only lasted about 2000 miles before I started to feel that dreaded crunch in my peddle stroke. I was vey pleased that for $15 dollars this one lasted nearly a year with just over 5000 miles logged on it. It may have been able to handle more if this wasn't one of the worst winters in Chicago. I would recommend this bottom bracket to anyone who is looking for a high quality, low price item. It is also very easy to install (with the proper know how of course) and comes with two crank bolts. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/1638792-sunlite-square-comp-cartridge-bottom-bracket-68mm-eng-square-taper](https://www.desertcart.com.sa/products/1638792-sunlite-square-comp-cartridge-bottom-bracket-68mm-eng-square-taper) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-04*
