SRAM X01 Eagle 12-Speed Rear Derailleur

The SRAM X01 Eagle 12-Speed Rear Derailleur ties the system together, driving precise gear changes across the entire cassette with a titanium spring and durable, forged aluminum body. The Roller Bearing Clutch, long revered for its nearly unbeatable chain stabilization, gets an update with a repositioned upper pulley and larger lower pulley to accommodate the extra chain length needed to run such a wide range of cogs.

SRAM GX Eagle 12-Speed Rear Derailleur Lunar, 52T

The SRAM GX Eagle 12-Speed Rear Derailleur harmoniously shifts through all 12 gears of your Eagle drivetrain without noisy chain slap or annoying ghost shifts holding you back on the trail. Borrowing shifting technologies from its pricier XO1 sibling, the GX Eagle 12-Speed Rear Derailleur is a low-cost alternative that retains SRAM's X-Sync 14-tooth lower pulley system, X-Horizon parallelogram design, and Type 3 Roller Bearing Clutch.

New-Old-Stock Zeus (3/32″) Alloy Chainring (52T and 119 mm BCD)…Heavy Shopwear

New-Old-Stock Zeus (3/32") Alloy Chainring (52T and 119 mm BCD)...Heavy Shopwear 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: This offering is for a new-old-stock (but heavily shopworn) Zeus aluminum alloy 52T chainring with a bolt-circle diameter (BCD) of 119 mm. This BCD sizing has been out of current production for a number of years and as we understand it, this BCD sizing is proprietary to the vintage Zeus crankset. As a result, we are guessing there are very few available in today's market (with this BCD), especially in new-old-stock (albeit heavily shopworn) condition. We have not had the opportunity to acquire many Zeus branded components, but we believe such components to be at or near top-end coming out of Spain. Some colleagues would comment they rival Campagnolo quality from the same era. I don't know if that is true, but I think most would agree vintage Zeus components would be part of the discussion. We also want to confirm this is a derailleur compatible chainring with the relatively standard beveled teeth that measure 3/32" thick...and we confirmed this measurement with our calipers...as the teeth clearly measure about 2 mm thick (or 3/32") at their base. Please also note these large chainrings appear to pre-date many of today's design features typically found on larger chainrings...so there are no shift ramps/pins and no chain guard pin...just the traditional beveled teeth. Lastly, I see front-side chamfered (grooved) chainring bolt-holes that will ensure a flush mount of the chainring bolts (not that this is a huge deal, but the feature does make for a cleaner cosmetic look). With respect to cosmetic condition, the chainring rates as poor...with heavy shopwear (scuffs and scratches, as evident in the close-up pictures to the left). Functionally, however, the chainring is new and unused, as the teeth show no visible signs of wear. I can also confirm the chainring pictured is the next one to ship, as I have a couple of these left in stock. Listing Update...this is my last one in this model/size/finish.

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.
