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: This item for sale is a new Shimano Cartridge bottom bracket...model BB-ES30. Some of it's specifications include the following: Cup type/size: English threaded...1.37" cups x 24 threads per inch (tpi) Shell width: 73 mm Spindle/axle type: Octalink (V2) Spindle/axle length: 118 mm Production locale: Made in Japan Please note the spindle/axle length is fairly important, because we believe Shimano made this model bottom bracket in several spindle lengths (because this model bottom bracket was matched with a couple of different cranksets...depending on the spindle length) and this offering is for one of the longer spindle lengths. From what we can tell, Shimano intended this longer spindle to be used when a chain line of 50.0 mm was desired (measured from the center of the seat tube to the middle chainring on a triple crankset). We believe this chain line was usually desired when the front derailleur was mounted on an oversized seat tube...pushing the front derailleur further to the right. We also want to emphasize this bottom bracket incorporates Shimano's advanced Octalink technology, which resulted in a complete re-design of the bottom bracket to include a hollow (and larger) 22 mm pipe billet spindle/axle with an 8-spline interface to the crank arm...for greater strength and reduced weight. Additionally, it is important to note that Shimano designed two different Octalink spindle ends...a V1 design with each spline measuring 5 mm long x 2.2 mm wide (intended primarily for it's XTR, Dura-Ace, Ultegra and 105 Octalink compatible cranksets)...and a V2 design with each spline measuring 9 mm long x 2.8 mm wide (intended primairly for it's various Deore series, Tiagra and Sora Octalink compatible cranksets). Our research further indicates this model/size was intended for selected Shimano mountain bike cranksets from the first half of this decade. More specifically, it's compatible with Shimano's Deore triple crankset (Models FC-M510...beginning in 2002 when this crankset was updated to accept this 8-spline interface)...among others...so a bottom bracket designed for Shimano's base-level groupset among it's higher-end mountain bike components (although please 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 that this offering is of inferior quality in this one regard. Also (and as noted above), the V2 Octalink spindle ends are compatible with other 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 empasize this last point, because chainline has a direct impact on shifting performance, so even though selected Shimano crank arms may have the same V2 Octalink 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. As for condition, these units were bulk packed, so not in perfect cosmetic condition, but functionally they are new...having never been mounted or used.

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.
