New-Old-Stock Campagnolo (Campy) 53T Chainring (135mm BCD)...Second Quality

Description: New-Old-Stock Campagnolo (Campy) 53T Chainring...Five-Arm Compatible...Second Quality 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...We have come across a few of these new-old-stock chainrings that have small tooth blemishes (i.e., small chips/flaws in the tops of a few teeth) and/or scuffs/scratches from not being stored properly. We have included pictures of the next chainring to ship and while we see some of these blemishes, I still believe this chainring is still functionally fine. Although, with the noted flaws/blemishes, we have elected to sell this offering at a discount from our first quality stocks. Please also note that while we have multiple quantities listed for sale, we will repeatedly update the pictures to reflect the next offering that will sell/ship. Original listing... This offering is for a new-old-stock 53T aluminum alloy Campagnolo chainring. The bolt-circle-diameter (BCD) is 135 mm and the chain guard pin placement is centered between two bolt holes, which means it will mount as the large chainring on most non-compact Campy five-arm double and triple cranksets. It’s a good quality chainring that includes shift ramps/pins, but it’s still one step below Campy’s Ultra-Drive chainrings (in terms of it's function and finish...with the latter characterized best as a somewhat flat/understated gray finish). As a result, we believe they are Veloce quality chainrings, but they will still function on other Campy cranksets (as discussed in more detail below). These chainrings are considered 9-speed compatible, but we noted the thickness of these chainrings at the bolt holes is almost identical to similar 10-speed chainrings. More specifically, when measuring the thickness with our digital calipers, both the 10-speed and 9-speed rings measure about 3.0 mm…...with no more than a 0.1 mm difference noted in the handful of chainrings we measured...so effectively the same thickness. We mention this, because we believe the rings will function equally well on a 9-speed or 10-speed drivetrain. These chainrings are also a suitable replacement for 7/8-speed drivetrains. Although, depending on the width of the chain you are using with one of these older drivetrains, you may need to insert some spacers to push this chainring a little farther apart from the adjacent (and smaller) chainring. We should also mention this 53T ring is stamped as being compatible with a 39T smaller ring, so this would be it’s ideal match. Having said this, our experience has been that other chainring combinations function OK (as long as such combinations are within derailleur capacities). We would still recommend the 39T match for optimal shifting performance, but other sizes will still function with this 53T model. As mentioned above, these chainrings are Veloce quality and although Campy makes better chainrings...maybe nothing is a better value. These chainrings borrow heavily from Campy's higher-end models. Their design/geometry is similar, as are the multiple pins/grooves that facilitate the upshift of the chain to this larger chainring, as well as set points of specifically designed chainring teeth to facilitate the downshift to a smaller chainring. We should also mention these are stamped rings (as opposed to "cut", like Campy's higher-end rings), so their final production/machining will not be as precise. This will initially result in more drivetrain noise (from chainring teeth/chain interaction), but this noise should dissipate over time, as these chainrings break-in from use. In terms of condition, all of these chainrings were bulk-packed, so expect some shopwear-type marks. Additionally (and as noted above in the listing update), this particular chainring is being referred to as a second quality (but still functional) offering and please keep this in mind when considering this item. Please also note that while we may have multiple quantities listed for sale, we will repeatedly update the pictures to reflect the next offering that will sell/ship. Supplemental discussion…five-arm vs. four-arm design… Campagnolo introduced the four-arm crankset to it’s top-end Record groupset in the early 90’s. The four-arm design was only available with the Record crankset until 2004, when Campy incorporated the four-arm design into it’s Chorus cranksets. As for other Campy cranksets, they were re-designed in 2007, except for the Xenon model, to incorporate this four-arm design. It’s also important to note these changes did not affect BCD specifications, as the newer four-arm cranksets use the actual crankarm as the "fifth arm" for the purpose of mounting chainrings...but there are other compatibility issues. More specifically (and as alluded to above), we‘ve noted the following differences between a four-arm and a five-arm chainring: Chain Guard Pin Placement: The pin that prevents the chain from jamming between the crankarm and the large chainring needs to be placed in a different location relative to the chainring hole placement on a four-arm vs. a five-arm crankset. On a four-arm crankset, the pin needs to be placed in direct line with a chainring hole, since the crankarm acts as the "fifth arm" for the purpose of mounting the large chainring. In contrast, the pin must be positioned half-way between adjacent chainring holes on a five-arm crankset for the pin to be properly aligned with the crankarm. Grooved vs. Non-Grooved Chainring Holes: On a large five-arm chainring, each of the holes is chamfered (or grooved) to allow for standard chainring bolts to mount flush. However, on a large four-arm chainring, the chainring hole directly below the guard pin is not chamfered, since a special chainring bolt (that is unique to the other four) will screw directly into the back side of the crankarm from a mounting point that originates at the back side of the smaller chainring. In other words the four-arm chainring will have four grooved chainring holes on the front side and one that is not grooved...and regarding the latter...the purpose is to ensure a flush mount of the large chainring to the back side of the crankarm. I am sure there are other discussion points that we have unintentionally omitted, but hopefully this expanded listing description is helpful…and as always…if you have any other questions, please do not hesitate to contact us.

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.
