New Old Stock Shimano Cartridge-Style (50-Series) Bottom Bracket...68x115 mm (Made in Japan)
Thank you for your interest in this item and please visit our store for other offerings. We have very reasonable shipping terms and combine orders to save money (for customers) on shipping costs. We also maintain customer friendly return/refund/exchange policies.

Product Description:

Listing Update...This offering is for a legitimate new-old-stock Shimano cartridge bottom bracket that was made in Japan. This is not to say the newer model 50 series bottom brackets made outside of Japan are an inferior product, but at the same time we do want to distinguish these bottom brackets as a true new-old-stock offering for those folks working on a project where this is a consideration.

This offering is for a new-old-stock Shimano cartridge (sealed) bottom bracket...model BB-UN52. Some of it's specifications include the following:

  • Cup type/size: English threaded...1.37" cups x 24 threads per inch (tpi)

  • Shell width: 68 mm

  • Spindle/axle type: JIS square-tapered

  • Spindle/axle length: 115 mm

  • Production locale: Made in Japan

Please note the spindle/axle length is fairly important, because Shimano made this model bottom bracket in several spindle lengths to accommodate a handful of different cranksets.

Our research further indicates this particular bottom bracket matches the specs of a few early 90's road cranksets. More specifically, the Shimano 105 and RX100 double cranksets from the early 90's (Models FC-1055 and FC-A550, respectively) require these cartridge bottom bracket specs. We should also note the early 90's Shimano 600/Ultegra double crankset (Model FC-6400) requires these same cartridge bottom bracket specs (although this particular crankset would have originally been matched with a better quality offering...i.e., a 70-series or 90-series model bottom bracket). This offering is still compatible (with the above mentioned 600/Ultegra crankset) and will provide optimal chain line, but we would still recommend a better quality bottom bracket, if available.

The square-tapered spindle ends are compatible with other vintage Shimano cranksets, but please check your crankset's spindle/axle length requirements before attempting to use this offering with another Shimano crankset...and we can try to help in this regard should you have questions). We emphasize this last point, because chainline has a direct impact on shifting performance, so even though selected Shimano crank arms may have the same square-tapered interface, if their spindle/axle length requirements are different from this offering, then there is a strong possibility that shifting performance will suffer...so please pay particular attention to spindle lengths when it comes to purchasing any bottom bracket.

One other note...the left-side adjustable cup is made from a resin/plastic, which is common for Shimano 50-series and below cartridge bottom brackets. We prefer the aluminum alloy adjustable cups found on Shimano's higher-end cartridge bottom brackets, so we wanted to be clear this offering is of inferior quality in this one regard.

As for condition, these units are new and in their original retail box.

Note to international customers regarding shipping...
We apologize to those that feel some of our international shipping charges are too high. We only charge actual shipping rates, but once an order exceeds a certain amount, we hesitate to use the least expensive US Postal Services First Class International service. We feel this way, because this service is not trackable or insurable...so more risk of loss. We prefer the US Postal Services Priority Mail International service for more expensive orders, because this service is trackable at USPS.com and insurable...so less risk of loss. Unfortunately, this service is more expensive, especially for smaller/lighter packages, relative to the First Class International service. We are sorry about these higher shipping costs, but hopefully our notes help to explain why this is the case.

Note to international customers regarding customs...
We also apologize to those that feel their country import taxes, duties and brokerage fees are excessive. As a small US business, we are required by customs' laws to declare each order as a retail sale. Additionally, the declared order value must be equal to total store purchases and/or winning auction bids (less any shipping costs, as these are not considered in the declared value). As a result, each customer will be responsible for paying his/her own country taxes, duties and brokerage fees, which will be collected upon delivery. Again, we apologize for these additional costs, but we cannot afford the penalties and fines that come with breaking customs' laws...so we have to strictly abide by them.
